28" 4k panels are around 150 DPI, which is only 50% more than the "standard" 22" 1080p panel. 32" 8k panels, though, are going to be 275 DPI.

It is all personal experience, but my 21" 1080p monitors have awful pixelage that is very noticeable at standard view distances. Obviously, it has pitifully low DPI. Reasonable desktops (modern Gnome, latest KDE / Qt) now fully support DPI scaling, so there will be no problem going forward for people to use much more reasonable fidelity displays going forward because its not 2005 anymore, and we don't have to be bound by some awful fixed DPI in Windows that is incredibly low.
