Are you talking about MacOS being optimized for either 220 dpi (e.g.: 5K at 27") or 110 dpi? Many people are quite happy with 4K and 27"; that's what I'm using now. I monitor shopped last year and wrote up my experience in Nov. 2024:
Initial Thoughts on Dell UltraSharp U2723QE. Included are one or more links about the 4K vs. 5K at 27" issue. Some people are adamant that it makes a meaningful difference in text quality, for example, and some of us hardly notice a difference. So it's hard to give you a straight answer.
If you want a near 220 dpi display, and a 32 inch one, it's rumored ASUS is coming out with a 6K 32" display for around $1,200 in the near future (hopefully).
But whether you're looking at 27" or 32" displays, one thing I've noticed...I don't recall 5K or 6K displays offered at 120-Hz refresh rates. All I recall checking into had 60-Hz refresh rates, except maybe a Viewsonic (see below).
On the cheaper end of 5K 27" displays, ASUS has one for around $800 and Viewsonic for around $950; the ASUS has strong reviews, but it's USB-C DisplayPort Alt Mode (which should work fine) and the Viewsonic is Thunderbolt 4, and
per a Viewsonic page:
- 60Hz refresh rate, overclockable to 75Hz
Overclockable? A computer display's refresh rate? I've never heard of such a thing before, and don't know what's involved.
4K at 32" is lower dpi than 4K at 27".
If I were shopping right now, I'd be torn between a recent Dell release that's 27", 4K and 120-Hz at a great price, and that ASUS or Viewsonic (but that's a big jump in price).
If you want 32", Mac-recommended dpi (6K?) and 120-Hz refresh rate, I think something is going to have to give.
