I received my g7 one day last week on firmware 1009. Picture is superb but a lot of little bugs. Mine doesn't auto switch on when pc or xbox one x is powered up. Playing on warzone I randomly keep getting like a little frame on the bottom and right hand edge almost like it's, windowed. I checked and its always fullscreen. If I make a change to the resolution or frame size.. It goes... For a few minutes then comes back. If I select the xbox menu on pc whilst playing warzone... There's a delay, like it goes from hdr to non hdr and screen goes blank for a moment. I never had this issue on my acer predator. I've set the nvidia menu to 144hz 10 bit rgb. But in the monitor options it's always 240hz and in warzone its, set to 240hz even though I change it back to 144hz.. It'll go back!
What is your gpu?
