HDR support for windows 11

Hi Nadeem. I'm Greg, 10 years awarded Windows MVP, here to help you.

I would contact LG Support which is included with the monitor purchase for at least the first year, during which they must get it working properly or repair or replace it under warranty.

Try these troubleshooting steps for HDR monitor display in Windows 11:

Hi, I've no idea if this is related; reading
KB5000842 CU Windows 10 v2004 build 19041.906 and v20H2 19042.906
it says

- suggesting at least that MS has been fiddling around in that area.

You might try uninstalling that update.
