HDMI suddenly stopped working.

Q: HDMI suddenly stopped working.

I have a duel monitor setup where one was plugged into HDMI and the other into VGA. Both were running off of my NVIDIA graphics card (i also have Intel 4000 Graphics which came with my processor but is not in use).
When playing a game - my HDMI monitor just shut off. My VGA continuing to work.
I have tried many things such as reinstalling drivers but nothing has seemed to work. My Intel 4000 Graphics are failing to work also. I am yet to look inside of my PC to see if anything has moved out of place.
I've tried googling and I've found nothing of use. If anyone has a solution that would be great! - P.S I'm new to the forums

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Laptop: HP 15-R005TXOS: Windows 8.1 x64Laptop Purchased: September 2014TV: SONY KLV-40W562D About 1 week back, my HDMI output suddenly stopped working. On connecting the cable, there is no activity. I tried all of the available solutions includingPressing Win+P and selecting 'Extend Screen' or 'Duplicate Screen'Going to Device Manager and Disabling then enabling Intel HD driverTrying to update Intel HD Driver from Device Manager (It said that I already have the latest version)Plugging cable more tightlyKeeping TV switched on before plugging cableKeeping TV switched off before plugging cable, then switching onUpdating NVIDIA GEFORCE 820M drivers (820M comes with this laptop model)Trying both the available HDMI ports in the TVCompletely resetting my laptop to factory settings using HP recovery toolNone of the above steps worked for me. The 'Screen Resolution' window doesn't detect any other display, neither does Intel Graphics Properties window. There is no option on the 'Graphics Options' submenu which helps to select another screen (Graphics Options is shown in the right click menu). Below are my Graphics Adapter properties  I have ruled out any problems in my TV because I also have a RaspberryPi 2B, which works flawlessly with the same TV and HDMI cable. So, there is no problem with the cable and the TV. I have tried downloading compatible drivers from Intel's website but on installing, they give the following error when I try to install. NOTE: ...

Hi, I use HDMI output to connect to my TV a lot. One day I was using it without issue, disconnected the cable to move the laptop and when I reconnected it didn't work. I tried using (Win + P) and another dedicated keyboard shortcut (Fn + F4) to chage the display, neither would restore the TV display. I can still connect to a projector using VGA and I know the TV and HDMI cable are still good because they both work with my Windows 8 laptop and bluray player.

I'm just not sure how to start troubleshooting. I don't see display ports in the device manager and the graphics card says "This device is working properly." So where do I go from here?

Thanks in advance for any suggestions!

A:HDMI out suddenly stopped working. Don't know how to troubleshoot.

Do some quick checks on the cable. First you can think about if you have bent the cable in any weard ways. If so that could have damaged the cable. You are NEVER supposed to fold a cable as it can break the small cables inside of it.

Secoundly have a look at the pin's on each side of the cable, Are any of them bent? If so this could be the cause.

Suddenly my HDMI 2 connection with the LG TV has stopped working.

When I switch in Input to HDMI 2 it comes up on screen Connecting as usual but then reverts to no signal.

I?ve taken the lead out and in again but it still won?t connect.

I'm an oldie and nervous of this stuff.
I haven?t changed anything ? it was working earlier but just didn?t work when I switched as usual to HDMI 2

I have recently purchased a HP Pavilion 22bw 21.5 inch monitor so that I may hook my PS3 and PC up to it at the same time,(HDMI and DVI respectfully). Things have been working great so far until today.  I was installing a game onto my PS3 hard-drive and switched back over to my PC. After about 20 minutes, I switched back and the screen was blank. I restarted my PS3 and notcied that while the HDMI output was being detected(no out of signal range messages or any of that), the screen remained black and the monitor's native control screens were blinking. Switching back to my PC, and all was fine. I have tried everything I could on the PS3 end( reset it to factory defaults and everything) and still no dice. I hooked it up to our flat screen in the livinging room and it works like a charm. Plugging it back into my monitor after that showed no improvmenet. So, the PS3 seems fine, the HDMI cable itself seems fine as well. So that just leaves Mr. Monitor. I haven't had any trouble with it prior to this point and I am infact using my PC and monitor right now to type this post. Any and all help would be great appreciated. Thank you! -Anthony

Okay, this is the weirdest problem I've ever hard with computers. Here's what happened:

1. I had a few years old Pentium D 2,8GHz processor running on Asus P5VDC-X mobo. PQI 566MHz DDR2 and GF 7600GS 256mb PCI-E, 350W power.
2. I updated the mobo to Asus P5L-MX to support faster PCI-E cards. Everything worked fine, despite the processor ran too hot (58C on high use)
3. Because of the overheating I replaced the thermal paste but it had no effect on the temperature.
4. I thought I used too much paste so I replaced the paste again.
---
5. Bang, no video when I turn on the computer. I tried taking off everything part by part but nothing worked. It didn't work even when I only had processor and used the integrated graphics port. Tried resetting the bios too.
6. Nothing worked so I put back the old P5VDC-X and it worked like charm.
7. I thought it was logical that the problem was caused because of the mobo so I bought a new one, Asrock G31M-S.
8. No video... Did the same steps to this one too. It also had integrated gfx but it didn't work either.
9. The old P5VDC-X still works.

So I have no idea what's causing the problem. Is it the CPU? Mobo? PSU? RAM? I have no speaker on my case so I can't hear any beeps, but it won't start loading the OS from the hardrive and my USB mouse won't turn on. Tried using a differen't monitor too.

The main point is why it stopped working suddenly on new mobo's but still works with the old P5VDC-X? A... Read more

Two new motherboards tells us you made the same simple install error in both of them.
Tell us more about power supply, memory, cable.
Did you make sure the memory was correct for both new boards, and what is the memory on the old board. Would also like to know the power supply and other hard ware.
What happens with the most basic, simple install. Does everything light up?

If you used the same hard drive with the same Windows install on the two motherboards, that is the problem. Windows has detected that you have changed the motherboard and will not operate unless you reinstall Windows on the drive on each new motherboard... One install for each motherboard.
My guess is that you will be fine if you change hard drives or do reinstalls or repair installs of the Windows on the new motherboard.

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".========================...

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.

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.

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

Hey guys,

So I put together a new PC running Windows 10 Pro around 3 months ago and everything was working perfect till 2 days ago when my mic suddenly stopped working. I use a Steelseries Siberia V2 headset and the headphones work fine, but the mic is not picking up any noise at all. I tried plugging in both the back and front ports and my realtek always detects that a mic has been plugged in, but it simply won't work. I thought maybe my mic got busted so I also tried using an A4 Tech headset that I had lying around in the office but it has the same issue, the mic won't work. I looked around online for possible solutions and tried the following with no luck:
Ensured the mic was set as the default device and that its volume settings were maxed out.Tried disabling all sound effects (noise suppression, acoustic echo cancellation etc).Uninstalled all audio drivers and reinstalled the latest realtek drivers on my motherboard's webpage: GIGABYTE - Motherboard - Socket 1151 - GA-Z170MX-Gaming 5 (rev. 1.0) Uninstalled all audio drivers and reinstalled the latest realtek drivers on realtek's own webpage: RealtekUninstalled all audio drivers and let Windows auto-install drivers.I even uninstalled all realtek drivers and tried using the standard "high definition audio device drivers."

Not to be harsh, but when you get it working again thru what ever means you might have to do, make an image on a flash drive or what ever you choose and then, if the SSD has failed completely, install a new one and use the image to bring you back to the time of your last backup.

Good morning everyone, and a Merry Christmas!

I'm going to try to make this as brief as possible, while still including every detail I possibly can.

Today I received a few cool gadgets for Christmas that I wanted to install on my PC. I realized I was short on USB slots, so I tried to install a secondary set of USB slots. I plugged it in wrong twice in a row, due to me misreading my motherboard. After a few restarts, my computer wouldn't boot. I attempted to clear my CMOS, which didn't help. I then turned off my power supply's switch, then turned it back on. After I did this my PC booted, but I was fronted with a boot screen that said the CMOS settings were wrong. I was confused as to what this meant, and my options were F1 to Bios, or F2 to default settings and continue. After booting, my Razer Deathadder quit working. Now, at this point, I'm not sure why exactly I did this, but I reinstalled Windows. I am using Windows XP Pro -32 bit. After reinstalling all my drivers, I realized that NONE of my USB ports were working. My keyboard, mouse, webcam, nothing worked. I updated my Windows, BIOS, drivers, everything is new.

In the screen for Hardware, all my Root USB kits have exclamation points, and it says they aren't functioning properly. I have NO idea what the hell is going on, and if anyone has any ideas or comments, please please share them with me.

Hi,

I've been using the Microsoft Wireless Broadband router (MN-500) to connect to the internet. This afternoon, while I was away, the wireless connection was suddenly lost. The internet is fine, because when i plug my computer directly into the router (via ethernet), i am able to access the internet. However, the router does not seem to broadcast a wireless signal for the LAN.

I've reset the router, both manually and via the software and reconfigured the network. After this process, the Wireless Network sometimes appears momentarily in Windows...but the connection drops before it can connect.

All the lights on the router light up as normal and it indicates that both the wireless LAN and the WAN are working properly. I have no idea why I can't connect to the network wirelessly though...

Any thoughts?

My Acer ES1-111M HDMI has stopped working. It was working perfect until about a week ago. I believe it's due to a resent Windows 10 update. HDMI doesn't show anywhere in Device Manager. I tried going back to Windows 8.1 , but it didn't help. I reinstalled Windows 10 Clean Install and still no HDMI output. When I plug into my TV my TV detects a HDMI device has been connected but just flashes No Signal. I have tried every driver available including the test drivers from Intel.Almost 2 years ago I bought this to replace my HP laptop that had the exact same problem. When this happened on this Acer notebook I connected my HP to the TV Via the VGA/RGB cable. Now this Is where it gets weird. I got the HP connected and working with the RGB cable and out of curiosity I connected the HDMI cable to the HP and it made that happy noise saying it found the new device and for some reason started working. Since, I have read on the web that when this happens connecting the VGA cable first then the HDMI cable will force the PC to detect a non working port on the HDMI. Or possibly over the 2 years I've had this HP it received an update that restored the HDMI functionality. Problem is I can't test that theory on this ES1-111M because it only has a single HDMI output. I see this problem all over the web and wonder how many people don,t even know there HDMI port is dead because they never use it.

Hi,

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?

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.

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

My Acer ES1-111M HDMI has stopped working. It was working perfect until about a week ago. I believe it's due to a resent Windows 10 update. HDMI doesn't show anywhere in Device Manager. I tried going back to Windows 8.1 , but it didn't help. I reinstalled Windows 10 Clean Install and still no HDMI output. When I plug into my TV my TV detects a HDMI device has been connected but just flashes No Signal. I have tried every driver available including the test drivers from Intel.Almost 2 years ago I bought this to replace my HP laptop that had the exact same problem. When this happened on this Acer notebook I connected my HP to the TV Via the VGA/RGB cable. Now this Is where it gets weird. I got the HP connected and working with the RGB cable and out of curiosity I connected the HDMI cable to the HP and it made that happy noise saying it found the new device and for some reason started working. Since, I have read on the web that when this happens connecting the VGA cable first then the HDMI cable will force the PC to detect a non working port on the HDMI. Or possibly over the 2 years I've had this HP it received an update that restored the HDMI functionality. Problem is I can't test that theory on this ES1-111M because it only has a single HDMI output. I see this problem all over the web and wonder how many people don,t even know there HDMI port is dead because they never use it.

I've been running my xbox through this PC for months now and I havent had any problems, although I do need to bring up HP My Display in order for the hdmi to work correctly. I tried to connect my xbox one to the computer as usual last night but this time it said 'no signal'. I have checked to see if other hdmi cables would work (they do not) and I have tried the hdmi cable usually used for the PC on the TV and my xbox connects fine. I don't know of any recent update that may have caused something to go wrong, I can't get it to work.

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.

The HDMI connection to a video screen stopped working on this notebook.  The cable works with another notebook.  The problem might be associated with a recent Windows HP update.

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?

I have an XPS 13 that I wanted to use for work this weekend, the power adapter just stopped working. It's done this a couple of times in the past for a short period, but this time it's been for 6 hours or more.
I wasted over an hour on that *** "Dell.com" website trying to submit a support ticket or something, but of course you avoid wasting time and money for contacting customers.
It is still under warranty. What do I do????

A:XPS 13 adapter suddenly stopped working.

Hi,
Thank you for reaching out to Dell Community Forum.
Please boot into BIOS <F2> and check what is the status of the adapter is listed as.
Does the light on the adapter switch off, when it is not working?
Please private message us the service tag of the system along with your email id.
(Note: please don't mention the service tag or email id on the public forum as it contains your personal information).

(Be gentle with me I am a middle aged lady not all that computer-savvy!)

My desktop PC is connected by ethernet to my D-Link G604T and I give my paying lodgers free wireless acess on their laptops.

This arrangement has worked perfectly for three years.

Now, suddenly, I am connected to the Net but nobody can get connected from their laptops.

The ONLY thing that has changed recently is that I did a reformat on my PC. That's all I did, I didn't unplug anything, just the simple reformat one does by putting in the Windows disk. Can that have caused this?

I've restarted the D-Link, and tried unplugging it, to no avail. I'm not all that brilliant with computers so I am now at a dead end.

Can anyone help?

Hello,  I have an Envy17 and yesterday the touchpad suddenly stopped. No warning no nothing. It was working fine and then I closed the laptop for a few (did not shut down all the way) and the next time I opened it (bout an hr later) the pad was dead. Tried uninstalling and reinstalling the driver, numerous re-boots and installing computer/windows updates. Still does  not work. Have tried to double click the opper corner in case it was accidentally turned off but still nothing. When you go into settings, it says it is working properly. Anything else I can try?  ThanksLacyayn

l was typing a document yesterday and then suddenly the enter key stopped working closely followed by the "t, i, o, g, :, and UP keys.

Any idea what has caused this and how I can fix it? [trying to avoid buying a new keyboard... laptop user... sony vaio - vgn/c1z.]

Thanks.
 

A:Certain keys suddenly stopped working

Boot into safe mode or command prompt.

See if keyboard works. Or even in BIOS and see if the UP key works. Make sure its not a software issue (virus). if those keys still don't work... you have 2 choices:

1 - Buy a USB keyboard for $10~25 (cheap and easy)
2 - Order a new keyboard from SONY and install it yourself of pay a tech. Most likely will require taking apart the notebook.

A friend of mine is using #1.

A:USB ports suddenly stopped working!!

Tell us the brand and model of computer, whether a desktop or a laptop, and the location of the usb ports... whether front or back, or whether we are talking about a powered external hub, or a multimedia box in the middle of the computer which has a 9 in 1, 15 in 1, or similar memory card reader with USB ports.
Are the USB ports built into the case, or on a pci card slot on the back of the computer.
Generally, USB ports do not fail. There are a few times when they do because any electronics made with chips, thyristors, and printed circuits can fail. But USB ports are among the most rare of failures... except when you are using multiports.
On inexpensive USB connections, they all share one connector... If you have four or five ports on one connector to the motherboard, then those in use will reduce the power that is accessible on lower quality units.
