HDMI Display Not working after current Windows 11 Update
I see that on my Surface Pro 6 the HDMI stops functioning on the current update.
I tried the Surface Diagnostic Toolkit and it once corrected the issues ( about 4 weeks back) but then the issue again resurfaced and the tool kit was of no use.
I then reset the device. The HDMI external monitor worked till the cumulative updates were applied and then it stopped again.

2022-10-18T01:44:47.087+00:00 I am experiencing this same problem, but no luck with the "hard" reboot mentioned above. The cord and external monitor haven't changed, but I did install a bunch of updates between it working and it not working. Anyone else have solutions? This is really frustrating...

2022-10-18T09:56:47.947+00:00 I'm having the same issue. Worked perfectly fine until the recent update. Tried new cables, different monitors etc. It has to be a Windows 11 update bug.

2022-11-25T19:32:59.083+00:00 I had a similar issue. After getting windows 11 updates, the colors of the HDMI display had been changed.
This is how I fixed it: link rgb-color-issue-in-hdmi-port-due-to-windows-11-update-for-amd-9e400c10ef13
I assume that the same process I have followed will help to resolve this issue
