HDMI output randomly stopped working?

Q: HDMI output randomly stopped working?

Hey,

Recently, when connecting my desktop PC to my TV over HDMI, all it shows is 'no signal'. It was working fine before then and I know it isn't the TV or the HDMI cable through testing. Has anyone got any ideas what's happened and how to fix this?

P.S: I would write some PC specs but I would need to be able to use a screen for my computer to see them so...

Preferred Solution: HDMI output randomly stopped working?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I have a Toshiba Satellite A305-S6898 laptop with Windows Vista (64 bit). For two years, I have watched movies on my TV via the HDMI connection. Recently, this stopped working (I had not installed anything new or updated the computer). The HDMI cable is definitely still good. My laptop could not connect with the external display. I tried everything I could think of including making sure the drivers were up to date (they were) and the handy reboot method. Nothing worked until I went into the device manager, right clicked on the graphics card and uninstalled and reinstalled it. Using this method, I got it to connect again for a couple of days, though I had to uninstall and reinstall every time to make it work. This has stopped working now too though. I am at a loss. Any suggestions would be helpful. Thanks.

Hello, I have been using this computer for 2 years without having any issue. I have it connected to my TV through HDMI. Since last Sunday the computer seems to have lost the HDMI output signal. I've tried it in 2 different TVs and it doesn't show anything, not even Windows loading..However if I plug it to an VGA monitor through its VGA port, it works fine. I've updated the latest Intel HDMI drivers (found a link in this forum) but it didn't work.Could it be a driver update issue? I'm using Windows 7, but don't remember a system update ultimately... I'm afraid it can be hardware related.. Cheers

Hey!

I have a Portege R705 and for around 2 years I've had a setup with two samsung Syncmaster 2443 displays, one connected by VGA and 1 with a hdmi to dvi cable.

I've never experienced any problems until one of the screens could not detect a signal anymore. Neither monitor can detect the hdmi signal and both detect the VGA.

I have proceeded to purchase a hdmi to dvi adapter and connect the dvi cable that was delivered with the monitor to my screen but without success.

I'm pretty much out of ideas, has anyone experienced something similar or has anyone got any ideas on how to fix it?

many thanks,

Matthias

A:Portege R705 - HDMI output has stopped working

It is somehow strange that you have noticed this problem for no reason.
Have you may changed anything, installed some additional software, update or anything that can be responsible for this?

When you test only one of these both monitor do you have this problems?

A:HDMI sound randomly stopped working

The HDMI is generated by the video card. If the HDMI is set as the default audio playback device and there is still no audio, its most likey a problem in the video card.

One thing you haven't tried, reseating the video card. Its a long shot but give it a try. Power off the PC before reseating (unplugging and plugging back in).

My laptop crashed when removing the HDMI cable... totally dead... had to pull the battery to get it restarted. Now unfortunately the HDMI output is no longer recognizing the TV unless there is a second VGA monitor connected. Does this sound like a hardware issue?

A:HDMI output not working.

Sure sounds like it.

But first, go to Control Panel > Display > Change Display Settings > and click the Detect button with the HDMI connected to the TV.

I have been operating under the assumption that you should never "hot plug" HDMI connections. Turn off the laptop and TV, connect the cable, then turn them on.

I've tried all the HDMI inputs on my TV, downloading the latest drivers for my video card and went through all the menu's on my tv looking for settings that might turn off the HDMI functions, but without any luck.

Your laptop might be outputting a higher resolution than the TV can display. You mentioned it was a DLP TV so its probably only 720p, so if you laptop is outputting 1080p it might not work.

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!

Test with a different monitor/TV. That will determine if its a PC or TV issue.

Hello everyone,
I have a bit of a problem here. My AMD HDMI Output Audio Device is not working even though its set on default on playback devices and the computer and monitor sound is on. Was wondering whats wrong here.
My apologies if there were similar threads about this, as I just made an account and didn't get to check them up. Although I did search google and there were few cases with people that were using NVIDIA, since I'm not using it I would like to know how to solve this.

My playback device for my HDMI output is an AMD HDMI Output. I just got a new Bush Smart TV after cracking my old LG. HDMI output sound worked perfectly fine on my old tv and it works fine on my other Samsung TV. However the soud only refuses to work on my new Bush TV.

The picture works fine and I can see everything perfectly on the tv screen, but the sound just wont work and only works on the laptop.

Whenever I test my AMD HDMI Output with this TV, I get the error message saying - This Device is being used by another application. Please close any devices that are playing audio to this device and try again.

I don't get this error message when connected to my other TV(s). Sound and Picture works perfectly fine, yet the sound doesn't work on my new TV.

Does anyone know how I can fix this problem? I tried to update my sound driver, but it's up to date, and I've made sure that it is the correct playback device selected. Nothing seems to work though.

Hi,

I have an HP dv6500 laptop with NVIDIA GeForce 8400M GS (HDMI output). I just bought a philips 8404 LCD TV.
When I try to connect the laptop to the LCD, nothing happens. I can't get any video displayed on the TV.
I know that both the cable and the TV HDMI port are fine beacuse when connected to the XBOX they work without a problem.
I can see the TV on the NVIDIA control panel, it is recognized as "Philips FTV", but when set to dual display nothing happens, and when set to use the philips tv only, the laptop screen goes black (as it should), but nothing on the TV.

I have the TV for few days now, weird thing is that one time (and one time only) I did manage to see the computer on the TV via the HDMI cable. I didn't do anything special - just clicked Fn F4 and it was there. but it only worked one time and I can't get it to work again (but at least I know the HDMI port on the laptop is also fine). When I connect the cable to the TV I do hear the "windows new item detected" sound on the computer, so there is a connection but no picture at all.

I tried re-installing the NVIDIA drivers but nothing helps.
Any help or suggestion would be appreciated...I waited for an HDTV for a long time and now I finally have it but without the PC link it's rather futile

I have a strange feeling that re-installing windows7 would solve it (as it does for most things ), but I'm trying to avoid this annoying lengthy process...

Cheers,
Idan

Hi everybody,I have an incomprensible problem with my X270. I use an external monitor in 4K with an HDMI cable (my dock don't have displayport). But the 4K output isn't working all the time. When I turn on the computer sometimes I only have 1080p resolution and I can't change it (for 4K, I can for less like 720p). But sometimes, it is working fine. Even if I don't change anything. For exemple, I do an update, restart my computer and after it, without changing anything, I only obtain 1080p. If I restart 3 hours later, I can have 4K. (I am on Windows 10)But, I also have Debian on my computer but I prefer W10 when I use my 4K monitor because Debian isn't perfect with 4K. But on Debian, the computer can offer 4K on the monitor everytimes. There is no problem to detect 4K on Debian. So I don't understand why it is not working with W10.Any of you have the same problem or a solution?

Hi guys,
I recently upgraded to Windows 10 from Windows 7 on my HP G60 125CA laptop. I never had this issue with Windows 7, but ever since upgrading to Windows 10, I can no longer use the HDMI port to use an external monitor. The problem is, the computer recognizes the external, as it makes a sound AND shows there's two monitors (the laptop and the external) in the Display Settings, but I get no signal on any monitor I use, no matter what HDMI cord I use. I've tried adjusting the resolution to 1920x1080 for my HDTV and that didn't work. I still get no signal. I have the latest NVIDIA graphics driver. NVIDIA GeForce 82000M G is the video card. I've tried re-installing, completely removing the driver, doing a clean install, installing an older driver and none work. I even tried extending, duplicate, show desktop only on 1, show desktop only on 2, etc.

If you guys could help, I'd greatly appreciate it.

Hi all,
 
For some reason, my HDMI audio output to my television stopped working about two months ago. I finally came across a solution this afternoon to fix it, but as soon as I reset the laptop, it reverted back.
 
First, some specs:
 
Laptop: MSI GT70
OS: Windows 10 x64 Home
Audio Driver: Realtek HD Audio v.6.0.1.7324
 
Seems like I've tried everything I can find on forums. Here's a rundown of everything I've checked:
 
1. Playback Devices -> Show Disabled/Disconnected Devices? Yes
2. Restarted Windows Audio Service? Yes
3. Device Manager -> Sound, Video, and Display Controllers -> Scan for Hardware Changes? Yes. (This was the fix this afternoon, is no longer detecting TV for an audio device after reset)
4. HDMI cable integrity -> verified.
5. Remove and reinstall audio driver? Yes
6. Remove cable from both laptop and TV and re-connect? Yes
7. Remove cable and restart laptop and tv? Yes
8. Repeat above step in various different ways.
9. Verify audio path on TV HDMI port is working? Yes, with a different laptop using same cable.
 
I didn't have this problem for the last two years I've owned the laptop. I've been to sever hotels with different TV's and it's been plug-and-play the entire time - until recently.
 
Like I said before, it worked briefly this afternoon again until I reset the laptop. Now the above steps I used to correct the issue the first time are no longer working. Does anyone else have any ideas?

the HDMI sound is most likely off your GPU but that series seems to not have a HDMI port so that is odd. If you can make sure your onboard audio is on in your BIOS and also run the tool on this page so that you can update all your system info for us. System Info - See Your System Specs

Ok here is the scenerio.

- Been using a 24" monitor and a 32" Monitor in conjunction for quite some time (couple years) with out a hitch. I think i had a power failure and came home to my 32" monitor not displaying anything (fyi, i had the desktops as duplicated on both screens, Each one are in separate rooms)

The 24" monitor is hooked via the DVI and the monitor is hooked up DVI to HDMI adapter and the HDMI goes to my stereo and then to the 32" TV.

Here is what i've tried.
- Remove and reinstall drivers
- Swap the HDMI cables
- I even tried a different video card (nvidia 550 ti)
- Even re-installed windows!!

On my stereo receiver (Harmon Kardon AVR 700) it flashes HDMI as if it doesnt have a signal going to it, if there was signal to it then it would just be a solid HDMI light.

I've tried resetting my Stereo receiver. No luck. Oh and I also tried all 3 of my HDMI slots available.

The ONLY way i could get it to work, is to plug the computer directly to the TV (using the same dvi to HDMI adapter and port on the video card) I know I can just bypass my receiver, but i dont really want to lol. As i use it as a HTPC A LOT!

Posting here is kinda my last resort as i'm pretty stumped at this. Keep in mind that everything was working fine up untill the power surge.

A:2nd video output stopped working......

sounds like you've narrowed down the trouble to your receiver...possibly something got fried during the power outtage. Are you using any kind of UPS / surge protection? Does the receiver work okay otherwise?

sounds to me like the receiver is the culprit.

I have started having an issue over the past week (config/drivers/etc not changed in months) where sound will randomly not be output by HDMI.

System config/specs...
Win7 SP1 all patches, nearly a stock install... only running WMC and XBMC.
Only 3rd part stuff installed are SpeedFan an ATI drivers. (problem occurs if Speedfan is running, or not)
system runs 16 hrs per day, auto shutdown at night.
Dell Optiplex, 6GB RAM + Core2Duo E7400, SSD - no swap file
HDMI is the default, and only sound device enabled (disabled all others in OS)

History... was working perfectly for over 2 years. One Win7 rebuild in that time. Updated video card once and drivers occasionally.
Symptom...
Approx half the time when I start up WMC or XBMC sound output via HDMI does not work. The other half of the time it works fine.
-- to get it working I can open Sound CPL and run "test". Sound will play through HDMI and all is fine usually the rest of the day, but sometimes it has the problem again if I don't use the system for several hours.
-- it never faults (stops working) while in use... only on initial XBMC or WMC startup... again system is always running hours before I start the apps.

Any ideas?

A:HDMI Sound randomly not working - test in settings gets it working?

This sounds like a problem with the video driver pack (also includes hdmi audio driver)
I would completely remove what you have now then download and reinstall the latest fresh again.
It could just be a glitch in the matrix so to speak.

My HDMI has stopped working, I was told to download all updates and I think I have done this... I visited HP.co.uk and dowloaded all updates after it identified my computer, but nothing appears to have changed. Any help greatly appreciated.  

A:HDMI has stopped working

Clive235 Hello;Allow me to welcome you to the HP forums!Anytime someone comes here running Win10 and complains about something suddenly not working, I immediately suspect Windows Driver updates.Unfortunately, Win10 automatically forces driver updates on all of us, without our knowledge, and without our permission -- and when this happens, a working PC is suddenly "broken".  This might have happened to you.You need to go into Settings, Update & Security --> Windows Update.Then, choose Advanced Options --> History to see when updates were last applied.  If you see any that include device drivers, those could be the problem. So, if you can, you should see if you can rollback the drivers that are causing the problem.  You do this by going into Device Manager, seeing if the appropriate device is still listed, and if so, trying to rollback the last driver update.And if that fixes the problem, then consider disabling future driver updates using the information in the link:  http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.h...Good Luck========================================================================I am a volunteer and I do not work for, nor do I represent, HP.---------------------------------------------------------------If my posts helped you, please click the Thumbs-Up symbol on my post to say thanks.If my posts solved your problem please click "Accept As Solution".========================...

i have a nice little set up with an HDMI plug near my vista laptop that connects to my HD TV some 30 feet away. this way i don't have to tote my laptop to the TV when i want to stream internet video. i set it all up about a month ago and everything worked fine until yesterday. now when i plug in my HDMI cable to my laptop and switch my video source over to PC on my TV it doesn't detect any video. i know that the connection is solid because when i unplug the HDMI cable from my laptop the option to switch to the PC source on the TV goes away. i recently updated vista with some "required" update but don't know what it was or how to resolve this. any suggestions?

A:HDMI out stopped working

You could do a restore to before the update. This ill remove the updates and you can find out if its due to that.

I'd try a second hdmi cable to eliminate the cable. Being that long it may have been damaged.

3rd, update your video drivers.

Hope something easy fixes it.

Hi. A few weeks ago my Z70-80's HDMI port randomly stopped working, no intermittence, no warning, just stopped. It was fine in the morning, working as intended. I then had to run some errands so I shut my laptop down. I came back a few hours later tried to project to second screen but nothing. Thinking it was software and/or driver related I've tried everything from rolling back windows 10 to updating GPU drivers, even the chipset got an update. Can a HDMI port just randomly stop working like that? VGA out is fine, just not the HDMI. If anyone has any ideas I might be able to try.... Thanks all.

A:Z70-80 HDMI out stopped working

I'm sorry I should have included some of the other things I've tried, save wasting everyone's time. I've tried a different HDMI Cable, different TV, updated Windows 10, even joined the insider program in the hope a beta version of windows 10 might fix it. But n luck with anything. Strangely though my tv will detect a hdmi source but displays 'No signal' it's frustrating

so I have a dell xps1530 with vista. awhile ago i used my laptops hdmi to my tv, the sound and everything worked fine. for some reason now i can't get the sound to default over to it. i know how to usually do it but when i hit make hdmi default audio nothing happens. the kicker is that when i hit 'test' on the hdmi the audio works through the tv, so the cord works and everything, my computer just won't let it become the default. i attached a hijack log if it helps

A:HDMI Audio stopped working

I searched many threads with similar titles but could not find a usable answer. I hope this post will have better luck.
My PC is connected from the graphics card to a Full HD TV via HDMI. This worked beautifully for 7 months with great video and audio via HDMI. Unfortunately it stopped working. The TV's HDMI ports and the cables work fine with other devices. On the PC I installed a new motherboard and reinstalled Windows. This is all working fine on a friend's display, including the DP connection from the graphics card. Sadly, however, the PC graphics card to TV HDMI connection is still not producing any picture or sound; not even the BIOS screen. The TV recognizes when the cable is attached (no cable vs. no signal messages) but no picture or sound results.

Some specs:
TV: Samsung UE32EH6030W
PC's OS Windows7 Pro - 74bit
Graphics card 1GB MSI Radeon HD 7770
Motherboard Asus H61MC
Processor Intel Pentium G850, Socket 1155, Dual Core, 2.90GHz
 

A:PC to Full HD TV via HDMI Stopped Working

I'm confused, did you replace the motherboard or the graphics card? If you are using a dedicated graphics card the motherboard would have little to nothing to do with outputting HDMI when a dedicated graphics card is installed. Does the second monitor show up in the AMD Catalyst Software? And even though the HDMI cable appears to work with another device, have you tried another HDMI cable?

Hi, my computer has stopped showing any signs of connection when plugged into my television. This is a major problem for me because I use my tv as a monitor. It was working perfectly fine, and has been for months, before I moved. Now I set everything up and it won't work. I tried using a different tv and a different hdmi cord to see if that was the issue but it still won't work. The tower wasn't damaged or at risk of being damaged in the move, I was very careful about that, so I'm not sure what's the problem. Thanks for any help you can offer me.
