I moved from a 1080p monitor to a 1440p one for my main display and it’s actually really worthwhile. Not only is your daily computing sharper, but multitasking becomes easier because smaller windows are still legible.
IMO it’s a lot easier on the eyes when things are sharper, too.
1080p is still more than enough, but I think 1440p is worth it for a screen you’re using for hours every day :)
