I have a dell 1920x1080 monitor and i usually have default windows screens like 1920x1200 ones and they work fine. I've been feeling like having something else on, like an elderscrollsonline desktop screen or a keep calm or just something else. I've tried 1920x1080 and 1920x1200 and they dont work, they're blurry. It's like a 3 year old tried to trace it with pixel art. any help is appreciated
