I also bumped into an article today. The "bad zone" is where fonts are too small or too big
Personally I own two 4k Dells 23.8" and find my fonts small. I was thinking about buying 27" 4k screens, but they are now also out of "comfort zone". But I will have a chance to test a 27-inch screen over weekends, to see if UI elements are more readable.
There are following settings that help so far:
Disable blurry fonts by enabling legacy subpixel antialiasing (
CGFontRenderingFontSmoothingDisabled
) and disabling font smoothing in Settings->GeneralIn System preferences->Accessibility->Display:
a. selectReduce transparency
(makes font more readable, as they are printed on paper)
b. IncreaseDisplay contrast
to 1.5
Use bigger fonts: TinkerTool and Command+J in Finder lists.
Adjust brightness/contrast of the monitor
B:30
C:60
at daytime, 0/40 at nightIn Preferences -> Display -> Color tab, select
Generic RGB profile
instead ofColor LCD
Regarding dithering, I believe it might come from the monitor itself (read your display specs, if it says 8bit + FRC, dithering will be added after video signal. I'm not sure if such thing can be captured using an external capture card. Maybe someone has a good Digital Camera with 50x zoom that can zoom into single pixels?)
