laptop connected to HDMI tv was working now keep getting no RGB signal

Q: laptop connected to HDMI tv was working now keep getting no RGB signal

I have a Toshiba satellite L305-S5875 I have it connected to my Vizio HDMI HDTV to watch netflix with. It has been working fine except for the past week. When I unplug the laptop to skype and then plug it back into the tv when I am done I get a, "NO RGB signal" message from the tv. I don't know why it is doing this, I have been able to use system restore to get it working again, but it is no longer working. Any ideas?

A: laptop connected to HDMI tv was working now keep getting no RGB signal

Try this:

Hold down the input button on the right side of the Tv. This is the bottom button
With the tv off, press and hold the bottom button (input)

When the TV powers up and you see the input menu, release and press the button
to change the mode to your preference.

Hope that helps.

Okay, so over the holidays I received a brand new Hisense television and I was watching movies and tv shows on my laptop on the big screen through an HDMI cable for a few weeks. Before that I was doing the same thing with the big screen in our living room for months. I got up one day and wanted to plug it in but I kept getting a message saying no signal. I had had it plugged in the night before and it worked just fine. Yes, I checked to make sure it was on the right setting, HDMI 1. I also tried plugging it in the other HDMI slots on the tv and it didn't work in those either. It is doing the same thing to our tv in the living room and it just doesn't make any sense. The only thing I can think of is that my computer has some kind of driver that just needs to be updated or something but I have no idea which one. HELP PLEASE!

I've recently purchased a Samsung T23A750 monitor and to my disappointment when I try to watch a movie the built in speakers are not functioning. I have a Sony Vaio Z216GX connected via HDMI to the monitor (HDMI-DVI) port. I can definitely see the video, but no audio is playing from the speakers. The built in speakers are not at fault- I did a self-diagnosis of the monitor and the speakers seem to work fine. I also set the monitor as the default for the audio and even when Win 7 says its functioning properly, the speakers still don't work. Conversely, setting the default to my PC speakers work fine. I'm sure its not the HDMI cable- I used the same one to hook my pc to my tv with everything working fine. Any ideas??

I bought a new HDMI cable yesterday, hooked it up to my laptop and TV and it worked just as expected. I unplugged the cable went away a few hours and when I came back to use it again and the TV was receiving no signal, Black screen with no sound. The laptop recognises the TV and says the connection is working properly but the TV shows nothing. The cable works between my Ipad and TV so it definitely looks like a setting issue on the laptop which is strange as I haven't changed anything manually between it working and then not. The TV is on the correct input and I have set the laptop to duplicate on a second screen. Tried a few things like changing the resolution and refresh rate but no luck.

Any ideas are appreciated. TIA

Hello I own Asus u81a-rx05 laptop.

Today I wanted to watch a video stored in my laptop on my tv so I hook up the hdmi cable to the tv and my laptop.

My laptop detects my tv but no image is displayed on my tv.
It worked before but i dont know why its not working now...

Latop detects the samsung 1080p tv 60hz.

"no signal" is displayed on my tv even if i change it to extended display or just projector(copy whats on my laptop screen)

I'm 100% sure that the cable is not the problem because i tested on my ps3.

Any help would be nice. THANKS!

Hi All,

I just set-up my new Asus computer with an Asus monitor. It seemed like a straight-forward task. I hooked up both the VGA and HDMI cables to the nVIDIA graphics card slot in the back of the tower.

I keeping getting this message "VGA No Signal". I tested the VGA cable by using it on my old computer. It works fine. I used my old cable on the new monitor and same message.

If I remove the HDMI cable from the graphic card slot the monitor works! I figured once I had Windows 7 set-up it would take the HDMI cable but no such luck.

Is there something wrong with this new monitor, the graphic card slot or I just missed something.

Also, I find the system is very slow to start-up even though the computer is much more powerful than my six year old computer.

Thanks, ms

Hey There,
For about 2 years I have connected my laptop to my tv with an hdmi cord and it worked beautifully. I used extend display and configured everything with the Nivdia Control Panel. About 2 weeks ago the TV stop detecting the signal from the laptop. I bought a new hdmi cord thinking it had somehow broke - but the new cord still didn't work. The driver was already up to date so uninstalled and reinstalled it. I have done this several times and still there is no signal. The device manager detects the card and says it's functioning properly. The mobility center says the display is connected and the Nvidia Panel shows the Sony TV. But the TV is blank and say no signal - any suggestions? I'm not a computer genius but can figure things out if steps are given just not sure what to look for anymore.

System has two HDMI ports and one DVI. The DVI supports a monitor and HDMI is advertised as supporting two monitors. Neither of the HDMI ports are working. Contacted HP support and was told to return for warranty work (1 day old tower). Returned to store for replacement contacted HP support with second tower and was told same, return for warranty work.

I have an Elitebook 8530p that I am trying to connect to my TV so I can view online TV on my TV screen. I can stream the online TV and watch it on the laptop ok, and I can connect the laptop to the TV with HDMI cord and I see the picture on the TV too, but as soon as I push the play button and it starts to stream the Laptop freezes. This happens on both TV's in our house with different HDMI cords which leads me to believe it is an issue with the laptop (not the TV's or cords). I have tried pushing the Fn + F4 buttons to clone it but that makes no difference. I have tried changing the display settings but I don't really know what I am doing! Another post said to choose full HDMI setting but even though the laptop has a HMDI port it didn't appear to have that setting. Is it too old?

A:Laptop freezes when connected to TV through HDMI

The problem is most likely the video card driver, so yes technically your laptop is too old, but luckily you can save that geezer! If updating the drivers doesn't work then you can try changing resolutions.

Solution found here:
a. Click Start, and then click Control Panel.

b. Click System and Maintenance, click System, and then click Device Manager.
Note If Control Panel is in Classic View, double-click System, and then click Device Manager.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

c. In Device Manager, expand Display Adapters, right-click the display devices, and then click properties and under the driver tab click on Uninstall.

d. When you are prompted to confirm that you want to remove the device, click OK.

e. Restart the computer.

After the computer restarts, the drivers will be automatically installed. Check after this procedure. Also check if you have any exclamation mark or cross marks alongside the display devices listed in device manager.
You can update the drivers using windows update. Refer to the below mentioned link and use the steps provided accordingly -

You may also check if there are any updates for the drivers at the manufacturer website. You may even install the latest drivers from the manufacturer... Read more

I have connected my HP Laptop with Windows 8 to my TV through an HDMI port. I watch netflix and youtube. A couple times a day the sound will just quit working. I check the audio and it says it is still hooked up to the TV. The only way I can figure out how to get it working again is to restart the computer. This has never happened while audio was playing, just when it is not in use for a little while.

Any help would be appreciated.

Recently my hard drive went out and I had it replaced with a solid state drive. The problem I'm having now is when I hook up my Samsung Smart TV through an HDMI cable (also tried a new cable with same results) I get wavy, scrolling lines on my laptop that go away when I disconnect the cable. The lines don't show up on my TV and this didn't happen before having my computer repaired.

The Staples tech wants to charge me again for diagnosing it after paying over $270 for a diagnostics and replacement of the hard drive. He said it's not possible for it to be a problem with the new hard drive so it would be another charge even though it didn't do it before having it repaired and my computer reformatted. I'm concerned I'm going to burn something out if I keep using it this way but I also don't want to pay more if it's something simple. He said it could be the motherboard or graphics card but I'm not sure whether or not to trust him. I'm a senior with little technical knowledge.

I want to use an HDMI cable so I can watch Xfinity programming that's available online only. I can live with it doing this as long as it isn't hurting my computer. Any help or suggestions is greatly appreciated.

Hi, new here. After searching for information on my problem I could not find a single thread with the same issue.
Having said that, here goes.

I just bought a new TV and attempted to connect it to my laptop via HDMI. I have used both the laptop and the cable with other TV's in the past with no problem but when I connect the two the laptop powers off as if the power has been cut. It will not boot when the two are connected and only happens when the TV is on. The laptop will boot into safe mode but it seems that HDMI out is disabled in safe mode so I cannot test it. I have checked and my graphics drivers are current. Hope someone can help! Thanks.

More Information: I have since exchanged for a different TV (Different Brand) for an unrelated issue and it doesn't work with this one either, same issue.

Hey guys, I'm actually new here, so I am not sure if this is in the right forum page, but I need help. I have had a problem with my HDTV and laptop for a few months and finally decided to start a thread for help. The problem is that the HDTV is blurry and fuzzy when connected to my laptop via HDMI. However, I realize this is an overscanning issue, because in the AMD Catalyst Control Center, whenever I set the scaling for overscanning to 0%, the fuzzy text and screen is fixed, but the edges around the screen like the taskbar are cutoff the edge of the screen. I do not think my TV has an option for "Just Scan", but maybe you guys can find something I can't. Here is the manual:

I messed up display settings for when I attach a TV via HDMI to my laptop. I set the system to display only on the TV (OK, not a totally stupid idea) and then picked a resolution the TV doesn't support (that was TOTALLY stupid!) When I disconnect the TV, laptop display works as normal. As soon as I connect the TV, laptop screen blanks and TV goes to Invalid Format. I have tried to change display settings through the control panel with the TV disconnected, but as soon as I plug in the TV, it goes back to the bad resolution on the TV and no laptop display.

Is this stored in the registry somewhere? I want to reset the flag telling the system to display only on 2nd display.

Please help

Last year i bought a monitor that is hp la2405x because it has 1920x1200 resolution which i need because i need it to play online poker. I would connect my laptop to the monitor by vga cable. I noticed that the monitor would keep on going to sleep. Example i would be on the computer for few hours or play poker for few hours, then this message would show up. Then my HP monitor screen gets the no signal and then go to sleep and when im playing, i have to wait like 1 minute or so, then hold the power button on my laptop for a few seconds then it turns off.

A:Monitor No Signal or Going to Sleep When Connected To Laptop?

Does this mean this is 100 percent my laptops fault then? Does anyone know what i can do to fix this issue? Does anyone know why is it that if you wait 40 seconds then press/hold the power button, after few seconds it turns off then you press it again, then it shows RESUMING WINDOWS but if you do this too quickly after the no signal, then press/hold the power button basically turns off the computer, then powering it on again makes you start windows as oppose to resuming windows which takes much more time?
Its very annoying when playing poker and many tables and this happens b/c im going to be sitting out tables due to this.
Another thing i notice is let say im on the computer most of the day but not playing poker, the monitor would go out once a day maybe or not at all. However when im playing poker all day, it will happen at least 1 time a day, sometimes 2 or 3 etc. Rarely does it never have the no signal.
Of course when im on the laptop only and dont connect it to any monitor, i never have this issue.
Does this mean its my laptop and probably the overheating or using too much electricity on the computer? The vga is plugged to my laptop so it isn't loose. Im really confused at this and i basically cannot play poker if this happens as there is going to be at least 2 minutes downtime each time it happens.

Problem started a little over a month ago on my HP laptop running Windows 7 64bit.

When I connect the laptop to my either of my TVs through an hdmi cord everything works fine. Videos run smoothly and the audio is in sync as if there's no problem.

If I try to watch a video on just the laptop though the problems start. If I try to play anything (songs/videos) in Windows Media Player then it says "Windows media player encountered a problem while playing this file".

When I play a video on YouTube the video runs smoothly but there isn't any audio to go with it.

If I go to control panel - sound - speakers and headphone properties and try to play a test sound it says 'failed to play test tone'

Attempted to update the IDT High Definition Audio CODEC driver but windows said it was up to date. Same thing with the Intel(R) Display Audio driver.

A:hp laptop audio and video problems (unless connected through hdmi)

Are you leaving the HDMI cable connected to the PC when you try to us the PC's sound (IDT)? Generally, when an HDMI cable is plugged in and detected the sound automatically switches from the "Speakers" (the IDT) to HDMI as the default audio playback device and thus no regular PC sound.

Hey guys,

For the past few years I have been running a HDMI cable to my TV. I also have a DVI going to a monitor. I have it so when the HDMI is in, the screen is automatically on TV, if HDMI is out, it will go to monitor - ease of use when watching films on larger screen. Zero issues up until now.

Now though, the HDMI to my TV has 'No Signal'... But it is recognising that there is a HDMI source as when it isn't plugged into my PC it says 'No Cable Connected'

Seriously stressed out over this!

I have tried:

- Other HDMI cables
- Different HDMI ports on my TV
- Plugging HDMI into the back of my Xbox One's 'HDMI IN' port
- Updated my ATI drivers
- Booting with just the HDMI plugged in, no DVI

So PC folk, is this a Graphics Card issue, HDMI port issue, PSU issue, or hopefully simple settings issue?

Specs below:

AMD Radeon HD 5700 Series
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (8 CPUs), ~3.4GHz

A:DVI TV to HDMI Laptop Not Working - Help!

I have an HP dv3 series entertainment laptop.
When I first got my 32' polaroid HD TV about a year back, I began using an HDMI cable with the laptop to display it on the TV. It was simple really. Plug-n-play mostly. Just had to switch the input on the tv to HDMI-1.

In any case, last night I had no problem using my laptop with the HDMI to TV and it worked this morning also. However, last night I accidently pressed something on the remote and suddenly the tv's aspect ratio or resolution changed and my laptop's desktop was all out of wack! The icons were smaller and words were harder to read. Its like they all got shrunk down in size. So I goto my laptops resolution settings and changed it and then changed it back to the previous. NOW I cant even get my laptop to display on my TV!

My girlfriend has the same laptop as I do and when I plug her's in, it works just fine.
My xbox 360/PS3 both work with the HDMI.

I have used both cables on the laptop, 360, and PS3 and the only one that wont work is the laptop.
It just says on the TV when I plug it in "Not Support".

Please help! This is madness!

I'm sorry, I'm somewhat technologically impaired. I've been connecting my tv to my laptop via HDMI cable for several years and it's always worked fine. Today when I tried, the screens just turned back. My TV stopped saying no signal as if it recognized the computer, and the computer screen went black as if it were switching to the TV, but neither of them actually worked. I tried to go into my display settings to connect to a projector which I have had to select in the past, but it says no additional display was detected. When I tried to tell it to do it anyway, the laptop screen started turning on and off every few seconds so it was black, then back to my desktop, then black again.

The really wonky part is that when I tried starting up the computer with the HDMI cable already attached, it showed the windows startup and password screens on the TV as if it were working properly--but as soon as it loaded up the desktop it started turning the screen on and off again until I disconnected the HDMI.

I haven't changed any settings on my computer recently--the only new thing I've installed are some games off Steam. Something crazy's going on with my computer that has never happened before, could someone please help?

Verify the screen resolution and refresh rate.

Aside from that, try manually updating or reinstalling the laptop video drivers. The drivers should be available from the laptop manufacturers website (and are the only recommended drivers which should be used).

For some reason, when I tried to connect my laptop to my HDTV with the HDMI cable today, it did not work. Normally, as soon as I plug the cable into my laptop, my display immediately switches to the TV, but now my computer is not even detecting an additional display, or the HDMI plug. It was even working fine yesterday, but today, nothing. I have tried uninstalling and re-installing the graphics processor, setting the computer to second screen only, using a different cable, different TV port, all the usual stuff, but for some reason my laptop just will not detect the HDMI cable.

Here's the basic information for my computer:

The computer is an HP Pavilion g6 laptop. Thanks!

I've always used my HDMI cable to hook up an extended display of my laptop on my TV. Lately it will often not work. I typically end up figiting with it, unplugging and plugging back in the hdmi cable, turning the tv off then back on, closing my laptop and reopening it, etc...

Hi and thanks in advance for any help.
I am very confused with my problem, because I can not nail down where it comes from. I lost the connection of my laptop named above to a Panasonic TX28DTM1 TV. The most confusing is that I had achieved a fully functional connection using a scart (TV) to S-Video (laptop) cable and I have been using it for a while. Suddenly it stopped working and I can not get it to work again ever since.

I had not connected my laptop to TV in a while and when I tried to do it recently I realised the TV was not visible to my laptop, although I had sorted this problem in the past. When I had managed to get it working for the first time windows plug and play detected a new device (TV monitor) and automatically found and installed appropriate drivers. So when I found out the TV was not recognised from my laptop I did again a search for new hardware; windows detected it again but could not find any appropriate drivers. As I could not find any drivers from various Panasonic support web-pages, I decided to uninstall the "Unidentified new hardware". I was planning to upgrade to Windows 7 so I hoped after my upgrade Windows 7 Ultimate would detect the new hardware (TV) again and find the appropriate drivers. My upgrade was smooth and posed no problems, but checking for new hardware does not detect anything new now.
The only change between the last time I achieved the connection and when it stopped working was that I tried to address a conflict of my gra... Read more

I have tried different resolutions and different recovery rates, but to no avail. I know that the connections are good and that the TV input mode is the correct one.

I have just built a PC with the ASUS M4A88T-M motherboard which has Radeon HD 4250 on board graphics. OS is Windows 7 Pro.

I have installed all the motherboard/graphics drivers that were supplied on the CD, but I cannot get any video or audio output from the HDMI slot.

I know that there are sometimes issues getting the audio through the HDMI cable but there is no video signal either. The VGS & DVI slots are fine, and also using a DVI-HDMI cable works, but then I have to use separate audio cables.

Do you have to enable HDMI within Windows anywhere ?

I have tried two different TV?s with no signal on either, so it seems to be a PC issue.

Any help appreciated.

You can try to download the latest drivers from here:ASUSTeK Computer Inc. - Motherboards- ASUS M4A88T-M/USB3

Failing that, You can try to exchange the motherboard (for OEM Windows 7 to activate the replacement board must be the SAME model), or look into getting a video card

Hello everybody. First of all, I'd like to say that I am not very technically savvy, so I apologize for any ignorance on my part. I posted this issue and a follow up on another forum; however, that forum seems to be a little on the dead side, so I decided to ask you experts. For that reason, I am splitting this into the two days I have spent trying to figure this out (to no avail).

Day 1:

So basically, I've been connected up to this 37" Emprex HDTV for a few days (nothing great... use the nice Samsung for the PS3), with no problems... well, ok, one problem. While fine at first, yesterday the computer decided to stop picking up the HDMI audio, with Windows 7 listing it as "unplugged." I tried uninstalling, reinstalling, and rolling back the drivers as well as installing new ones (Realtek... not sure if it had anything to do with anything, but it was worth a shot) to no avail. That was only the start of the problems however.

This morning, everything (except for the audio, of course) was peachy. A few hours ago, however, the TV decided to just stop reading the HDMI signal all together. No video, no picture, no nothing. All I get is a blue screen that says "No signal." I've tried numerous cables, unplugged and replugged countless times, uninstalled and reinstalled all the drivers, and nothing. VGA works though, so that's what I'm using now. By the way, the problem occured after I had moved the TV to a new spot, so it's n... Read more

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Win7.

Also, when I connect my laptop to my TV via HDMI (Also on Win7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

Spent a while on google trying to find a solution, but unfortunately I couldn't find one. Thanks for any help on this.

A:PC To TV via HDMI. No signal.

Hi there
What do you get on your MAIN PC when you press the windows + P key. It should be settable to display on 2nd screen only.

It should allow you to switch monitors. The monitor probably isn't being recognized since your PC is set to display on your main screen only (by default).

Ensure the TV is switched on and the input set for HDMI. You'll probably have to change the resolution - laptops seem to work fine --desk tops seem to be different -- probably because of the difference in the graphics cards - especially built in ones.

Laptops recognize when a monitor is plugged in -- this isn't always the case with Desktop PC's so try it with the WIN +P key with the TV switched on of course and the HDMI cable plugged in.

If you DO get it to work don't forget to re-set the screen back to PC display before disconnecting or at the next boot if you don't have the TV plugged in you'll end up with a nice blank screen.

Whenever I plug in the HDMI cable, the Monitor Model (Acer K272HUL) and the correct max resolution (2560x1440) is being shown on screen of the Laptop (Screen resolution window).
Also, when selectimng the HDMI port I use on the monitor, the monitor does NOT say "no cable connected" which it does at all the other ports. So, seems that the principle connection between the Laptop and the Monitor works, but no signal is sent ... ???
After a little while, the monitor also says "No signal".
Now, I found on the web that the max. resolution of that monitor on HDMI seems to be 1920 x 1080 @60 Hertz, so I changed the resolution to that values but with no luck. Also reducing the repeat rate to 50Hz (by going to "advanced" and select it from the "mode" Button) does not help - monitor stays black.

Hey there @jim1200, Welcome to the HP Support Forums! It is a great place to find the help you need, from other users, HP experts and other support personnel. I understand that you are having trouble with connecting a display to your computer and you are getting no signal. I am happy to help with this. Does your computer have a discrete graphics card installed? If so and if you are trying to use the two HDMI ports on the back of the motherboard of the computer instead of an HDMI port on that video card, then that is the issue. If a video card is installed, the integrated graphics adapter is disabled. Try using the HDMI port on the back of the video card itself. If this is not the case let me know, but if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

I have recently hooked up two Samsung Syncmaster 2243s to my HP Compaq laptop at work (waiting on an email for the specific model for the Compaq and Nvidia Quadro video card). Unfortunately, the second monitor says "Check Signal Cable" and will not display anything. Here's how I have it set up:

The first monitor is hooked up to the laptop on the VGA port and works fine. I have used extended display with my laptop screen and Syncmaster with no trouble. I hooked up the second monitor to the HDMI port in my laptop with a DVI-HDMI cable. At no point (eg. when restarting) does the monitor show anything but "Check Signal Cable".

I have updated my drivers (windows and Nvidia) and tried removing my display adapter and restarting, forcing the computer to reinstall the drivers. I have rebooted with the second monitor attached and unatatched with no luck.

The key point is that the computer recognizes the second monitor (with the Nvidia control panel I can turn off the laptop screen and set both monitors as my extended display - second monitor still says no signal although the first monitor, which works, behaves as if it were part of an extended monitor). Further, the second monitor works normally, as it was used on a previous laptop via VGA. What could cause the "no signal cable"? I did buy a second DVI-HDMI cable with the same result. Any help would be most appreciated.

typically, dual monitors is not done with VGA, or if so, is implemented using a 'Y' cable.

I've just recently had to rebuild my HTPC with a newer version of Windows 7. I have been using an ATi HD5450 card in my setup for over a year now with no problems.

However, with this new build I've put on, I am now not getting any signal to my receiver from my HTPC. However, as soon as I turn on my TV, I get a signal to the receiver!! So I can get audio but always have to have the TV on, which is not how I remember it working before.

I am no nearer to finding out why all of a sudden there is no signal from my PC to receiver. I have carried out a few tests that Yamaha have advised me to as I thought the issue was with the receiver but it looks like a problem with the Windows 7 and codecs.

I've just checked and I am running the latest drivers for my card as well.

My Dell XPS 15 9530 from 2014 no longer seems to be able to connect via HDMI to TV or projector since I upgraded from Win 8 to Win 10. It worked before. I get "no signal" on the second screens.
Spent half a day already on this, googling and trying the following:
* Updating to the latest Dell drivers, Windows updates, and Nvidia updates.* Disabling either of Intel (HD Graphics 4600) or Nvidia (GT 750M) graphics cards* Rolling back to older versions of display drivers* Trying different HDMI cables* Running Dell's diagnostics tool* Lowering screen resolution* Restarting everything
But nothing works.
The external screens don't show up in Screen Properties. Pressing Fn+F8 brings up the four choises (Duplicate etc.) but nothing happens when I click any of those options.
Some posts I found via googling seem to suggest that Win 10 simply isn't compatible with HDMI in some laptop/graphic card/CPU configurations. Can this really be the case, or what can I do?

I've tried 2 TVs (Samsung HL67A750A1 and LNT2653HX) and they both give the same 'No Signal' error. For 8 months this setup has worked without an issue with both of these TVs.

The original issue started with the ATI 4650. The PC would still display without issue, but it would randomly freeze and then a few days later the motherboard started giving a diagnostic error code that the video RAM check during POST failed and the computer would no longer boot.

I installed an ATI 4870 I had and the computer booted fine and no more lockups. I was glad I finally figured out the issue. But then the next day the LNT2653HX LCD said 'No Signal' when turned on. A reboot/reconnect cable/re-seat video card, etc wouldn't help. I connected the PC to the HL67A750A1 and received the same error.

Both TVs will work fine with another PC and XBox 360. I installed the 4870 in the other working PC and immediately received the 'No Signal' error. I placed my 5870 back in the working PC and while it wouldn't show POST, it did display once Windows 7 booted (interestingly when I connect through my Denon Receiver, the PC will show POST on the HL67A750A1 - just not when directly connected).

The bad PC with the 4870 will boot to Windows and I can even connect to it through RealVNC and gain access to the file shares. When looking at the display properties, it only detects a VGA connection (the RealVNC I assume). I installed Powerstrip and the EDID information it is pulling from the registry is... Read more

Alright, this is the second morning this happened and I'm getting a little worried. Basically, I turned the computer on and the LCD TV that it's connected to doesn't pick up its HDMI signal. What I have to do is take the plug out and put it in another TV, get a signal there, then put it back in my main TV, and then it picks up. I haven't installed any new hardware or software since I started having this problem, and I haven't changed any settings. I've just been playing minecraft. The TV doesn't give me any problems otherwise.

I'd appreciate the help.

I just started having this problem on both of my laptops, Toshiba Satellite and an HP, and I have exactly the same problem on both of them. Both of them loose the signal as soon as windows starts loading so it has to do with windows 8 since I get a signal just before windows starts loading. I have tried to go to the display settings and on both of them will not detect my HDMI TV. I don't seem to be able to find a solution to this and it looks like there are quite a few people having the same problem but no solutions. Any ideas?

The last time I used my computer was last night and all was well, when I went to bed I put my computer to "sleep" like usual and went to bed. I get up this morning and "wake it up" and i'm getting a "no signal" screen on my TV. So I look at the display on my receiver and the HDMI logo isn't lit up like it should be. I restart the computer to see if that helps, as soon as the boot logo screen comes on the HDMI logo lights up and I can see the display normally all the way until the logon screen should come up, then the HDMI logo goes away and I get "no signal" again.

Now i'm in safe mode w/networking but can't get status of my video card due to being in safe mode. Does this sound like a classic case of a bad video card or am I jumping the gun? Any way, short of swapping out the video card, I can do some troubleshooting to confirm what the problem is?

A:No HDMI signal once Win7 loads

Have I finally stumped you guys? Normally you guys resolve my issues pretty easily.

Still in safe mode here, haven't figured out what the problem is. It can't be my HDMI cord though cause i'm still using that same cord ATM. Kind of thinking it can't be my video card either cause i'm still connected to the display via the HDMI on it. This is strange! I've been connected to my HDTV for months now, nearly a year, and all of a sudden this happens?? Baffling!

I still have my 22" display hooked up via DVI, i'm gonna restart my machine and see if I get anything to display on it once Windows loads......didn't try that this morning. If so, looks like I'll be getting a 24"+ monitor sooner than I thought cause my 22" is on the verge of going'll be fine for a while then the screen will get noticeably brighter for a few seconds before it blacks out. I can turn it off for a while then turn it back on and it'll be good to go for a little while but then it'll do the same thing.

I'm trying to connect my new PC with a LG TV (49UF7077), but the TV keeps saying "no signal" no matter what I try. The TV sees that something is connected though. And the Geforce control panel quickly and correctly finds the TV and its native resolution and other options. Windows correctly allows extended desktop and other options. I'm using the latest Windows 10 Home and an EVGA GTX 1070 with the latest driver, and checked and controlled new HDMI cable.

What I've tried:
* restarting everything
* resetting the TV
* trying different HDMI ports (although this TV clearly has one certain one which is "the right one" in terms of color support)
* disabling "hdmi ultra deep color" (something which the TV suggests as a fix)
* outputting to TV only (I also have the regular monitor on the DVI port)
* lower resolutions (as if the hardware wouldn't support 4K60)
* connecting a low end Windows 10 laptop using the same cable - WORKS!
* contacting LG support (they couldn't give a solution)

Any ideas?

Hey guys,

I got a weird problem here concerning an Acer computer (AM5811-E1512) and an Acer monitor. The problem is that whenever I boot the

computer while the monitor is connected with an HDMI cable to the right HDMI output (the one from the graphic card, ATI HD 4350), I

get a *No signal* message on the monitor UNTIL it gets to the *Choose a User* screen. At that point, the display appears and

everything is fine. I tested the same monitor/computer with a VGA and a DVI cable and both worked fine and were actually showing the

booting screens. I work at a small repair store so I was able to test the monitor on another computer of the exact same model using

the HDMI cable and everything worked fine. So does anyone have any idea of what could be wrong? The computer is running Windows 7 and

everything is legit. Im just trying to figure out what could cause a *No Signal* message on the monitor until Windows is loaded,

which is stopping me from accessing stuff like the BIOS and Recovery Options when using an HDMI display.

I havent been able to find anything similar on the web...

Thank you for your time

I have connected my Samsung Ultrabook operating on Windows 7 64-bit to an HP Compaq LA2450x monitor using the HDMI port on the Samsung and a converter to the DVI port on the monitor. The monitor is showing no signal for DVI and going to sleep. Consequently I have not been able to use the monoitor yet and am still working off the ultrabook screen. Do I need to change any settings on the ultrabook in order to create a signal? Is there something else I might be missing? I have switched both computer and monitor off and restarted several times without any luck. I followed the manual installation instructions for the driver and it seems to be correctly installed.

Sometimes this can be a "Handshaking" Issue. Try powering down the laptop and unplug the monitor. (never plug or un plug HDMI while hot) when you have the hdmi cable plugged in, plug power to monitor and restart, that may help.

At some point last week I removed the HDMI cable from my video card to use with another device temporarily. Later, after plugging it back in I could not get anything to show up. I later hooked up an extra monitor I had laying around through one of the DVI ports and performed a system restore because the system apparently failed to boot. I have been unable to get the HDMI out to work properly.

When the HDTV is connected with the HDMI cable, both the TV and monitor hooked up via the DVI port behave as if there is no signal (e.g. displaying "no signal"). The DVI monitor does not go blank until what I assume is the Windows login screen shows up. At first all sound would stop too because I had set the HDMI out as the default sound device as well, but chaning to a different default sound device and plugging in the HDMI monitor no longer stops audio. I booted up in safe mode and the monitor plugged in via DVI port does not lose signal, but the HDMI monitor still shows nothing. I wasn't sure what do to from there.

So far I've tried uninstalling and reinstalling the driver for my graphics card, buying a new HDMI cable, and toying around with the card's settings in the Catalyst Command Center (although I barely did anything there).

So recently just rebuilt my setup with some newer components and had it running for couple of days then i went to load up Dead Rising 2 and HDMI signal drops now i have no signal whatsoever.

Have tried diferent cables, different monitor, vga cable, pushing graphics cards in, clear CMOS but still nothing.

New components are not the issue as i was playing Dead Island Riptide yesterday morning for 7 hours straight and pc has been running for couple of days, all i changed was relocated everything to a new case and upgraded my cooling system with new pump, res, rad, fittings.

These are the main components Asus 27" 3D LED Monitor, Gigabyte-990FXA-UD3, Watercooled AMD FX8350, 2x Watercooled MSI GTX580, 16gb Corsair Vengeance RAM, MaxRevo 1500w PSU then all my pumps res etc.

Anyone have any views into why this happened? Also because of the state of my system its extremely hard for me to pull out cards and test them on thier own or test other cards as i have to drain my loop everytime i need to remove or replace a card, so i kinda want to avoid doing that unless all else fails it might be something im overlooking for monitors as this is the first monitor i've used (usually ran from a 32" led tv until recently)

Any help would be great.

A:Did my graphics cards just die? HDMI Signal loss

do you have the 27 and the 32 hooked up together?

if so it might have been directed to the 32 inch tv sometimes they not the Bigger tv as the main

Hello, I am pretty decent with computers but not an expert. I am having a little trouble with my home theater PC display flickering. My video card is a Radeon HD 6900 and the drivers are up to date. I have the HDMI out of my PC going to an Onkyo 7.1ch HT-R590 receiver and it's output going to my LG 42" TV. My OS is Windows 7 Ultimate X64.

The system used to work perfectly fine but over time the display started to flicker at random times. I tried to hook my PC directly to my TV and it works perfectly fine, so I am 100% certain the problem is in the receiver. I did a bit of research and it appears to be a problem with my receiver over heating. I placed a 120mm fan on top which helped some but the problem is still there.

Now, if I run my HDMI to my TV, I cannot use 7.1ch surround sound. (Even after playing with Audio Return Channel) If I run optical to the receiver, my video card only puts out 5.1ch surround sound for some weird reason. So I did the next obvious choice, I ran a DVI to HDMI to my TV for video and HDMI to my receiver for audio. I thought it would trick it into thinking there was two displays but this does not work, I do not get audio.

I was wondering if you guys knew of any utilities that would allow me to output audio on one HDMI stream and video on my DVI port. I did a lot of looking around and it looks like DMCA calls for HDMI to be encrypted and you can't separate the stream. Or would I just be better off getting a separate audio card to connect to...

A:Display flickering, need help spliting HDMI signal

No, as far as I've heard/read, you can't circumvent DMCA - HDMI either carries HD audio and video, or it just carries video and you have to output audio via toslink/stereo from your computer to your receiver.

Have you cleaned your receiver, ie: used compressed air to remove the dirt and dust? Have you considered sending it in for repair?

This was working fine before I had to format my computer. I'm about six hours deep in this it's killing me. I'll provide you with any info I can, but I'm far from knowledgeable about this kind of thing.

The problem:

My setup:
Windows 7 64bit. I have a monitor as a main display and a TV connected as an extended display. The monitor is connected via DVI. The TV is connected via HDMI. The TV is a PDP-R04. My graphics card is an AMD Radeon R9 270X using the latest drivers (14.501.1003.0). The cable works tested on other devices with the same TV. The TV works. The source settings on the TV are correct.

Things I've tried:
- rolling back to previous display drivers
- uninstalling display drivers in safe mode and re-updating
- resetting CMOS to defaults
- booting computer with only the TV plugged in
- changing the TV's resolution settings

I am attempting to connect them via HDMI cord but no signal is coming through. I tried connecting my laptop to the TV using the same cord and it works fine so the TV, and the cable are obviously functional. But the Lenovo desktop will not come through, all I get is a no signal message on my TV. I thought that the HDMI port on the desktop was damaged or not functional so I took it back to Best Buy and exchanged it for an identical model. But the same issue is happening. I ran through all the basic checks, everything is plugged in and on the right TV input setting, tried using all of the HDMI ports on the TV (which all work with other devices), tried swapping around the cord ends, and the computer is plugged in.

Hey guys,
So here's my set-up:
I've got to 2 monitor plugged in my computer (1 HDMI and 1 DVI) and I wanted to plug my TV as well (for watching movie and TV show). So I bought an HDMI splitter to split my off-screen signal to my second moniter and my TV. Seems to work perfertly except for one thing: I lost my audio that was coming trough my HDMI to either my monitor or my TV. Usually I use my headset but when I'm watching a movie or what ever I love to relax and remove my headset so this is a bit of an issue. Anyone else already got this problem? Did I bought the right thing (HDMI splitter)? Can an HDMI splitter even split audio?

Thanks for the help guys!

Most likely just the way that particular splitter functions. Audio and proper HDCP support vary by brand/model.

I've not used one, so I can't make any recommendations.

Hey guys,
I have done some searching but to no avail. I have tried everything I can find/think of with absolutely no luck.

I have a brand new Samsung LN46B750 which I have connected to my desktop for use as an HTPC. VGA works fine, but I would much prefer to use a digital connection. SO, I have an HDMI <> DVI adapter and a monoprice HDMI cable connecting my GeForce 6800 to the HDMI/DVI port on the HDTV.

I have tried 182.5 and the latest Nvidia drivers as well as the generic W7 drivers. It's all the same.

Everything works fine in the OS so long as I make it past the Windows splash screen. And unfortunately, that never happens. I believe that the problem lies in the auto adjustment of the screen when 7 starts loading. (If I boot without the TV connected, and then connect after the splash screen has loaded, everything is perfect.) Is there any way to disable the auto detection/adjustment of the TV and just have the OS always boot into 1920x1080 @ 60 Hz. I am really tired of the blank or black screen every time I reboot. This is a terrible bug with W7 or EDID and it needs to be fixed now Microsoft!

Thank you!

hi all - ive got a problem with my new viewsonic vx2753mh-led monitor. its got 2x hdmi inputs and one vga.

the vga works straight off the bat, but whenever I try and plug the hdmi in it just says no input signal detected and goes black

I noticed in device manager that this was installed as 'generic non-pnp monitor' so after jumping through some hoops i managed to install the driver as 'viewsonic vx2753 SERIES'
Anyway this doesnt seem to have made a difference. still no input through the hdmi.

I have tested to cord on my samsung tv and it worked fine so it can't be a problem with the cord or the graphics card....

just some general info that might be of use:

the graphics is integrated on the intel i5 chip

it has a dvi out, hdmi out, and vga out.

A:Viewsonic LCD monitor not recognizing HDMI input signal.

I have a Viewsonic which I'm also trying to run a media PC to connected via an HDMI cable, and I have noticed the exact same thing.

It was working fine for awhile, but recently I have been receiving an error on screen saying the "HDMI to DVI cable as experienced an error" or something to that effect. Note: I am using strictly an HDMI cable, not an HDMI to DVI as the message states (can't explain why I'm getting that message). I did the same thing you did, tested the machine using the same cable on another tv, and it worked fine on the other tv. What's strange is I can connect the cable box to the tv using the identical HDMI cable and it worked fine. Tried again using the same cable from the PC to the tv, and either 1) blank screen, or 2) shrunken screen with the aforementioned error which will go blank once I open Media Center.

Sorry, I don't have an answer, but it seems to me Viewsonic hasn't made a good product in terms of connecting media PC's, for some reason. Of course, my tv is out of warranty at this point. If you find an answer, keep me posted, I'll do the same.
