> Your displays are high enough resolution that you may not notice the compromises being made, especially if you don’t get an opportunity to compare it with real fractional rendering, but the compromises are real, and pretty bad at lower resolutions. Pixel-perfect lines are unattainable to you, and that matters a lot in some things. And you might be shocked at how much crisper and better old, subpixel-enabled text rendering is on that same display.
Do you have a test case where I can see this in action?
Nothing handy, sorry. For comparable results, you’d need to use an old version of Mac OS X. Up to 10.13, I think, if you can ensure subpixel text rendering is active.
Sorry, what I mean is, is there an image or PDF I can bring up that will show me imperfect lines on these displays?
As for rendering of text, there is definitely antialiasing in play. Subpixel rendering is no longer used, but I don't think you need it at these resolutions anyway. I'm not even sure what the subpixel arrangement is of my display (is it neat columns of R -> G -> B, or larger R and B with smaller but more numerous G? At 250-some PPI, the pixels are too small to notice or care!). But, I agree that if I was using my old 1920x1200 monitor I would miss it.
