Windows 10: My HDMI port doesn't work after 5th December 2018 update (Win10)

My problem is very clear. After the 5th December 2018 upgrade, my HDMI port stopped work. I can't switch between my laptop screen to the external one. The monitor and HDMI cable works with other PCs. I was trying to upgrade and even downgrade graphics cards drivers - no result. I'm sure that this is because of Microsoft update. Probably this version was installed: KB4469342. In the description, we can read "Addresses an issue that causes display settings to stop working when changing a multi-monitor configuration.", but in my case, something went wrong. This option was working, now doesn't work.

What may I do to fix it? Install the older version of the update? But which one? I'm looking forward to the new, better update for windows 10...

Please, ASAP


Regards,

HDMI Port Stopped Working


I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?

 

win10 HDMI worked then stopped working

hi

win 10 w ASUS P8Z77-M motherboard using on board video. very vanilla setup.

after win10 upgrade, it took me a while to figure out I needed to update motherboard stuff but finally got HDMI monitor working.

then today a giant step backwards.

I plugged in a mini USB hub and now HDMI quit working under windows. It works fine when running diags initially but when it transitions to windows, no more HDMI signal. so unplugged usb hub but now no HDMI in windows. this blows. i appreciate it was my bad
not to do all mobo upgrades prior to win10, but this is nuts.

So i am open to suggestions on how to resolve this. I'm shocked HDMI would have stopped working in windows.

THanks,

Mike
