I am not too picky about the display size but DPI. 190-220 is a good range.
If you want a 32" monitor it should be 6K. 27" should be 5K and 24" should be 4K. Unsurprisingly, Apple has this correct at every display size.
As a Mac user, I partially disagree. I like 190-200, but I definitely don’t like 220. Before Retina, Apple’s flagship desktop monitors were at about 100 ppi or less. The then revered 30” Apple Cinena had display was 101 ppi. However, once they went Retina, they went to 220 ppi. IMO 220 is too high with their chosen default text size, and they should have stuck with their previous text sizing but Retinafied, at ~200 ppi. This corresponds to 5K at about 29-30”, but even 32” would be OK. 6K is too high.
Actually, 5K 27” and 6K 32” would be fine if they offered more scaled resolution options, but for some stupid reason they don’t, so in order to get them, people have to resort to 3rd party software.
BTW, another reason high ppi displays are so necessary in macOS is because Apple has removed subpixel anti-aliasing from the OS, so now the OS looks bad with anything under ~160 ppi unless you drop all the way back down to ~100 ppi. This is not true on Windows. It actually looks half decent on lower ppi displays, because it has sub-pixel anti-aliasing. The biggest difference is with 4K 32”. It’s OK on Windows, but it’s terrible on macOS, at usual ergonomic desktop seating distance (20-25”).
