Thx for the hint. I have that turned off already (Settings > System > Display > “Use HDR: OFF”). But it’s still on when I start the game.
Also what is weird, I tried a lot of other games on my new monitor and not single one of them turns on HDR on my monitor automatically. In most games there is a separate option in settings to turn on or off HDR.
And regards the monitor menu, there is no option to turn off HDR in monitor menu nor in OSD Sidekick app that allows you to control monitor options through Windows.
Any other suggestion?
