If you look at the Steam hardware survey, most users (as in, > 50%) are still using 1080p or below.

In part though that's not because all those users can't afford >1080p because some of them can it's that insanely high refresh rate monitors and esports players often use 1080p at >300Hz - even the ones without still use 1080p because driving up the frame rate drives down the input latency.

Whether it matters is a bigger issue, 30 to 60Hz I notice a huge difference, 60 to 144Hz@4K I can't tell but I'm old and don't play esports games.

I don't think this is contra to my original point. Nearly 50% of all users are running at greater-than 1080p resolutions, and presumably power users are overrepresented in the latter category (and certainly, it's not just the ~2.5% of Mac users pushing the average up)

FWIW, I didn't mean to reply to you in an argumentative way. Just proposing an answer to this:

I still see 1080p fairly often on new setups/laptops, basically, although 1440p and 4K are becoming more common on higher-end desktops. Then again, 1440p at 27" or 32" isn't really high dpi.

Writing this on 1280x1024 because it still works fine

The 5:4 aspect ratio is weird, especially in this era of everything 16:9, but it's a second monitor so usually only has one thing open
