I wanted to go 4K, but went with 1440p instead. A happy medium for now.

4k has the benefit of being exactly 4x 1080. I run the games i can (like RimWorld, ONI, Factorio) in 4k and the games i can't in 1080 which is perfectly upscaled to 4k (each pixel is just 4 pixels). 1080 is a bit low res but i think it's better than bad upscaling.

It's a nice middle ground for me who mainly use the monitor for productivity and 2D gaming.
