I have the S2725QE with the KVM switch and 27' is just so comfy as an all-rounder. It's also the lowest size where you can reasonably buy 4K from a mainstream manufacturer I think. Wish Samsung came out with the new-gen IPS Black (as Dell does with the S2725 line) finally since they own the technology, so I could avoid Dell, but eh.

I have a 28 inch 4k monitor specifically for my ps5, since i prefer 1440p ultrawide on the pc side, and the pixel density is definitely nice. For shits and giggles i tried to look as closely as possible at the screen and couldn't spot the individual pixels. Something i also like about it is that even games that don't run at native res still look like they are native when the ps5 upscales it. Either the upscaling is really good, or maybe it's just not noticable because of the smaller screen size. Either way it looks really good.

I want to someday switch to a 4k UW, but my current 1440p monitors are still so good that they don't feel "outdated" yet. Coming up on 10 years with one of them! 1440p, 165hz, IPS. It's been bombproof. And from Acer, of all companies.
