You'd need an 8k screen (or something a little bit less, but 8k is touted as the next big res after 4k, so we will stick with that) at 27 inches to hit 300 PPI.
Except you are nowhere near the point of distinguishing individual pixels at 300ppi from the normal viewing distance of a 27" which - due to your natural field of view limitations given you don't go to extreme neck/head nor eye movement - is close to its diagonal.
But even without your field of view limitations, your visual aquity
is limited, thus the resolution you can actually see, or at least the "norm" for normal vision 20/20 can see, is limited to way lower than 300ppi - again, for normal viewing distances a 24-27" is subject to. For a smartphone that you often bring a few inches from your nose, sure, 300 ppi is nice.
You could stick with your 300ppi screens...guess with the same exact logic you believe all prints have to be 300dpi too (cause the 300 p/dpi is a printer's rule originally)...and that a 32in x 24in poster print is a severe lackluster if its is not reproduced from a 70MP digital file...or that a 48 sheet billboard (240" x 120") requires a shy off 2,600 MP (yes, 2.6 Terrapixels). Guess what: far from it. The resolution we can actually notice, is tied to our distance from the subject.
According to the visual acuity formula given in the wiki above, the 1800p 15" rMBP @ 227 ppi is nearly perfect, as a person with 20/20 vision cannot really distinguish higher resolution beyond 15"/39cm.
A 1440p 27", tho "just" 109ppi , appears just as perfect as the rMBP past 32in, and at around 3K (~1650p vertical) it would be nearly perfect at 27".
Yes, a 16:9 screen 27" @ 1800p is better than the average eye can see at its diagonal, and a 2160p is even better.
Sure, the elitists in OCN have to have 240Hz and 300ppi or nothing.
Much like full AA or nothing.
Good, whatever rocks your boat. just don't elevate your preference and misconceptions into general needs.Edited by pcfoo - 4/1/14 at 10:07pm
