I just ordered MAC and Macbook M1 and searching for best monitor solution.
While I don‘t have any of both, Dell Ultrasharp displays are really, really nice. I’m too looking for new monitors and this U2720Q is the one I’m looking for (two of them in fact) for My future Mini M1.
And yes, 4K is too low a resolution for a 27" IMO
Unfortunately, this is all what we have. Higher resolutions on the same 27 inch are almost inexistant except the LG ultrafine 5K Thunderbolt, and you cannot have two on a Mac Mini, which limits greatly the possibilitIes. Having 4K at 27 inch is totally acceptable And way better than anything you could find. Unfortunately, the Dell 4K 24 inch seems not to exist anymore.
Expect to run it scaled, thought. So you loose a bit of real estate. At 4K, you have two dimensions: 27 and 32 inch. The 32 inch will let you run it a bit less scaled, so you get real estate but text is a bit less sharp due to lower PPI. The 27 inch will have sharper text, but you’ll need to run it as a 1440p to be able to correctly read text on it. It’s not actually running at 1440p, but
text looks like a monitor on 1440p.
The other option is Pro XDR, which price is certainly overkill for any normal, non-Pro users.
Dell S2721QS is the runner up of the U2720Q. It would be my second choice. It‘s almost the same display, a bit less on the build quality but the price is very interesting. Since I tend to keep my display 8+ years, paying the extra for the U2720Q doesn’t really bother me. Decision is up to you.
USB-C and HDMI support is primordial, especially when running two displays or when you think to have another one in the future. This avoid requiring adapters.
