I have attached a screenshot of my LG 27UN850-W and you can see that the UI and text is not proportionally tiny or hard to read. With a 27" 4k monitor, you get 26,628 pixels per square inch.
#What you need for hdmi for mac 1080p#
With a 27" 1080p monitor, you get 6,653 pixels per square inch. Retina display is essentially all about packing in a high pixels per inch count. The concept above is exactly how built in Apple displays work. What VikingOSX said would be true with different display resolution settings, but that is not how Apple intended it to be set for a 4k monitor. Packing 4 times as many pixels into the same physical space results in much sharper text, lines, curves, etc. Double the horizontal (1920 = 3840) and double the vertical (1080 = 2160).īottom line, on screen, you have 4 times as many pixels making up the screen content, yet at the same visual size as 1080p. For each single pixel on 1080p, the 4k monitor displays four pixels, in a 2 x 2 grid.
If you double 1920 you get 3840 and double 10. Bear with me as this takes a bit (at least it did for me) to wrap your brain around. With a 4k display set in preferences to use its native "default for this display" resolution, what you see visually on screen with a 27" 4k monitor is exactly the same size as what you would see on a 27" 1080p monitor. I disagree with VikingOSX on this: " One consideration is that if you opt for a 4K display, everything will appear smaller on the screen" It is all I hoped for, and more, in that it solved the problem my previous monitor had with not waking up with my M1 Mac mini. To say that I have been pleased with the choice would be an understatement. After a great deal of reading and research, I purchased the recently released LG 27UN850-W.
