Hello there, I wish to play 1080p video in 4k resolution(monitor native) rather than 1440*1.5 in fullscreen mode on youtube. I have a monitor 4k resolution, my win10 setting is 150% scaling(recommended), the youtube viewport size is "2560x1440*1.5" with a "*1.5". When I change win10 to 100%, viewport is "3840x2160". This seems correct but the video quality is lower because it is not a x2 upscale from original 1080p youtube stream, but rather x1.5x1.33. Is there anyway for firefox to render video directly? I am aware I can change system scale each time to play video but that's not what I'm looking for. I guess since firefox is rendering text pixel perfect so it has a solution for this problem. Thanks

This isn't really something the Browser controls that comes from the O/S and GPU driver that controls scaling. I think you need to ask more help for this on a Windows forum since this deal with O/S and GPU driver issues. Youtube already has a scale optimizer when you use Youtube does that not work as well. I don't have issue running YT on a 2K monitor and GPU and Windows 10.
