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:

I think that is a wise decision, windows had never been the quickest to take on new variations in technology - what I suggest is to set a reminder for six months from now to check the progress of HDR support. Of course with Windows 11 now "spooling up" it may be an idea to check it's support for HDR, as it's a free update and may have better support, but there is a downside as the systems have changed quite a bit between Win10 & Win11 as have the hardware requirements We have our own Windows 11 support forum at Windows 11 Forum
