I used to be in the '4k or bust' camp, but then I realized that I needed 1.5x scaling on a 27" display to have my UI at a comfy size. That put me right back at 1440p screen real estate and you had to deal with fractional scaling issues.

Instead, I bought a good 27" 1440p monitor, and you know what? I am not the discerning connoisseur of pixels that I thought I was. Honestly, it's fine.

I will hold out with this setup until I can get a 8k 144hz monitor and a gpu to drive it for a reasonable price. I expect that will take another decade or so.
