Windows 10: After updating to windows 11 my factory HDMI port no longer works

I have an Acer Swift. I recently updated to windows 11.The factory HDMI port on my laptop no longer works. I've tried finding the device in device manager and it doesn't seem to exist.It looks like Windows 11 is treating it like a USB port. No amount of updating windows 11 with all the optional updates, or updating drivers fixes this.I finally got rid of this issue of windows 11 constantly crashing my laptop, now I plug my laptop into monitor that always worked before.... nothing.Why is windows 11 such a terrible product? How do I fix this immediately?

:)

 

Windows 11 does not work with Monitor in Display Port, but HDMI ¿?

Thanks, but I've already followed that (obvious) steps...

It's curious:

- If I start the computer with 1 monitor using Hdmi cable, it works (shown windows 11 fine)

- If I start the computer with 2 monitors (1 using hdmi cable, 1 using display port cable), it works (shown windows 11 fine in dual screen)

- If I start the computer with 1 monitor using Display Port cable, it works until windows 11 loads... shown Bios/Post boot... but then black screen not showing windows 11. It's a Microsoft Windows matter. I do press Shift + Start + Ctrl + B (to reset 'graphics') the monitor does a 'flick' but continue without showing windows 11.

 

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?

 

HDMI port no longer working

I upgraded my HP Pavilion dv7 laptop from windows 7 to windows 10 and my HDMI port seems to have disappeared from the device manager. The port no longer works. I am trying to use the HDMI port to hook up a second display because I can no longer extend
my desktop to the second monitor through the VGA port. Windows 10 does seems to override the AMD graphics driver I downloaded from the AMD web site. The video card is an AMD Radeon 6300M series card. Everytime I boot the laptop, I get a code 43 error on
the graphics driver in the device manager. disabling and then enabling the driver removes the error message, but the laptop refuses to recognize a second monitor hooked up to it. re-booting the computer simply envokes the same series of error codes with
the same end result.

any help appreciated.
