Can't enable Game HDR option on Samsung G65B 27" monitor. I have enabled HDR within windows 10, and the monitor says it's working, Netflix also, but the "Game HDR" option for some reason is greyed out? I have tried new hdmi 2.1 cable, and DP which came with the monitor. Game mode is enabled, and I have tried all the options with refresh rate and can't figure out why it's not working? I have Rx 7700 xt 12gb gpu with Ryzen 5700x3d and 32gb of ram. Can somebody please help? Thank you.
