Yeah but that will always be the case, unless you get a 5K display. 4K with scaling looks pretty sharp to me (and sure beat the 2540 x 1440p display I replaced!).The problem with the 27” is the DPI is too low. Even the 24” is less than Apple’s retina standard @184 DPI
(though my old eyes can’t really tell). Apple’s retina is about 218 DPI.
