Problem with HDR mode HP Omen x27 240hz

HP Omen x27 240hz
Microsoft Windows 10 (64-bit)

Hi, I bought this monitor around 3 months ago and everything was fine till today when I switched on HDR mode half of the screen was green. When hdr is off everything is working fine I even checked gpu for artifacts but 30min test didn't show anything wrong. So it is monitor defect or might be something else? Below I attached 2 photos (1 hdr on, 2 hdr off) Thanks for help.

Hello @pjeruk 

I think this is the first time Ive seen this type of issue reported with those gaming monitors. Ill try my best.

I need to clarify a few things though.


When you say it worked fine 3 months ago, was the HDR working too or is this the first time you used the HDR option?

What is the monitor connected to and how?

If a PC, what are the specs?
