I use a 24" 1440p screen. On a 1080p monitor (or 4k at 200% scaling) there isn't a lot of width left if you turn it, and if you go for more pixels than 2560x144

I use a 24" 1440p screen. On a 1080p monitor (or 4k at 200% scaling) there isn't a lot of width left if you turn it, and if you go for more pixels than 2560x1440 (at 100% scaling) the text gets too small on a 24".
