4K is great if you're doing a 2:1 scaling, such as a 1080p effective resolution. Thats fine for 24", but too big for 27" monitors IMHO, they are much better suited to 1440p (QHD). Doing 1440p equivalent on a 4K display is a 1.5x scaling and can be not as good due to interpolations and the non-integer scaling.I would get the 4k for macOS, because fonts should look much better.
What is a good 27" monitor for the 13"?
The LG Ultrafine looks nice, but is too $$$. I think 1440 would be a nice resolution on a 27". Any recommendations or is the Ultrafine the only good option?
How is it at QHD /1440p scaling? IMHO 1080p equivalent is too big at 27" diagonal.I got the LG 27UK850-W the other day. It's gorgeous because it has very good color and multiple ports
Of course. Also viewing distance and other factors as well. I stated my opinion, which doesn't apply to everyone.It depends upon how old you are, and how your eyesight is.
Old enough to have been coding BASIC & assembler on Apple ][ (not +)computers before the IBMPC existed.How old are you?
