HDMI is a popular high-quality connection method for both video and audio output, so it’s no wonder that so many people are using it.

Speaking of HDMI, many Windows users reported that the HDMI port is not working on their Windows 10 PCs and laptops.

Here are some quick examples of how these issues can manifest:

  • HDMI won’t work on laptop
    • In most cases, TV fails to recognize your laptop
  • HDMI audio won’t play
    • Oftentimes, video is available but audio won’t play
  • HDMI image is too big for the screen
    • Fortunately, installing the latest graphics driver updates should fix this problem within minutes
  • HDMI video is choppy
    • This usually happens when a second monitor is connected via HDMI

The most common problem with HDMI is that audio or video is missing and in most cases, that’s caused by driver incompatibility, but there are a few things that you can do to fix this problem.

If there’s no sound, video is missing, or simply your HDMI port is not working on PC, follow the steps listed below to refresh your audio and video drivers.


How can I solve HDMI output problems in Windows 10?

1. Check your hardware

Make sure that the HDMI connection didn’t slip out. Unplug and then plug the cable again. To make sure that the cable is well connected to your HDMI port, you can also invest in some new HDMI locks.

Turn on your HDMI TV or HDMI speaker and only then boot your PC. Then turn off the TV or speaker, unplug the devices altogether, wait for one minute, plug them back in and turn them on again.

Now that you refreshed your HDMI connection, follow the steps listed below.

Before diving into complex troubleshooting steps, first check your hardware. Make sure that the HDMI cable is inserted correctly and all the connections are fully functional.

So make sure that the Show disconnected devices option is enabled so that your PC can display all the devices connected to it.


3. Update your drivers

I had the same issue with Ideapad 530S IKB14 + Windows 10. After installing a few times a bunch of drivers, the problem was solved after I performed 2 actions:
+1. Uninstall Hyper-V Windows feature: Start -> Turn windows features on or off -> Untick Hyper-V.
+2. Reset BIOS to defaults.
Not sure which one did the trick but now I can play movies on TV from my laptop. What a big achievement!
Hope this help.

This worked for me (mind you, there are many issues with Win10 and HDMI, so you may need to continue searching for the answer that works for you).

Locate the driver/GFX adapter in Control Panel -> Device Manager. Right click and disable it (don’t worry, the default driver will take over and you will not lose your display). Make sure your display is powered on and connected (something in the Skylark mobile CPU that recovers only if the display is connected – I do not know if it is necessary for other hardware) and re-enable to driver. Depending on the cause for loss of HDMI operation, you may now need to go to the “Project” and reconfigure for extended / duplicate / second screen only.

Windows 10, without my permission, keeps installing new drivers on the background and every bloody time the Intel GPU driver is updated, HDMI dies again. You will notice the GFX driver installation from a quick screen flash and generally you also get that Windows system sound when a new device is connected. Most of the time the laptop’s native screen auto-brightness gets screwed up as well and you need to to the display settings and toggle the auto-brightness off and on (maybe even twice, like just now, for whatever reason).

Sad state of affairs that you cannot prevent driver installations and especially that they cause this kind of issue. …and this may not even help you. It depends on what of the numerous Win10 HDMI problems you are currently fighting with. Good Luck!

Forget about it~!
If You want to use HDMI go back to windows 8.1. this is just another attempt at scamming You out of Your money….thinking You’re going to fix this, without a computer geek charging a fortune to do what, is going to take, You an hour to do, at most~!
Get rid of Windows 10 it’s a farce; it’s no improvement over, 8.1, but at least the HDMI hookup worked~!

i’ve tried the compatibility way and when i run the setup file od driver it say’s this computer doesn’t meet the minimum requirements for installing this device. and yet it’s allready installed wtf?

I tried the rollback idea and that fixed my problem. I have a amd display adapter and they updated in September 2016, I rolled back to the November 2015 update and it’s now working fine.

I constantly have issues, and have done all suggested steps above, but it only works for a little while, then stops working again. I found the quickest way to get it working is to go to Device Manager, sound devices, and disable then re-enable to AMD device. It’s a pain, and I have to do it nearly daily, but I haven’t found a long-term solution yet and this is the quickest short term solution.

Yeah, I was lucky to be able to get back to Windows 7. I use my laptop with VGA hook up to my 39 inch tv to watch netflix and youtube….could not believe Windows 10 would not detect TV. If I plugged in VGA and turned computer on,it would go straight to tv so I thought that was good enough but then my Netflix only had two large black stripes and I could not adjust resolution or figure a way to have full screen Netflix. Only took about 10 minuts to switch back to Windows 7 so I got lucky. Should not try fixing something that aint broken!!!

have your tv turned on and set to pc. have hdmi cable hooked to tv and pc. turn on your pc and give it a bit to start and it should go straight to tv disply…at least mine did. I could not get Netflix to play right so I switched back to Windows 7 and have all monitors detected with full picture controls!!!
