I thought I was around 33% better than 1080p efficient is why playing 1080p content on a 1440p monitor looks horrible because the pixels don’t line up?

1440p has 1.33x as many pixels as 1080p both horizontally and vertically, so it has 1.33x1.33=1.78x as many pixels in total.

"4k" or 2160p has 2x as many pixels as 1080p in each direction, so 2x2=4x as many in total.

2160p has 1.5x as many pixels as 1440p in each direction, so 2.25x as many in total.

When playing content at a non-native resolution, both downscaling but also especially upscaling by a non-integer factor produces a slightly blurry picture.
