Bought this monitor recently and have some questions. So this is all running off a 1080 ti factory clocks. When I kick HDR on in Destiny 2 I get a FPS drop of 20-30 frames at 4K resolution. Not sure if that's normal. Second I tried to change the resolution down to 1440p and the result was 4 borders around the game instead of filling the entire screen. Desktop resolution change checked out fine. Any ideas?
