There are some known HDR issues with certain

Read the reviews for this specific monitor, A significant number of people are having repetitive HDR issues

BenQ told me that the HDR issue is most often caused by firmware which makes me feel a little better.

When I turned HDR off, the Colors looked normal again and the monitor would try to emulate HDR.Luckily Amazon replaced the monitor for me without a second thought and the HDR issue resolved with the hardware replacement.

I tried other games like FF TYPE 0 and it look beautiful sincerely i recommend this monitor for hard core gaming :D

and it's nice and big thank u
