I’m using a 4K projector for gaming, and using a 21:9 ultra wide screen. I’m using a custom resolution in windows 11 to lock the screen to 3840x1620. All other games have worked fine, but Valhalla won’t display an ultra wide image. No matter what I try, it stretches the 3840x1620 image option into the 16:9 screen size above and below my normal screen. Please advise..
