First of all i love the 5k screen on the new iMac. Easily the best screen i have ever seen. However, Its still blocky when reading close up. I like to put my elbows on the computer desk table when i'm reading emails and browsing internet etc, so i'm quite close to the screen, and the pixels are really noticeable. Will 8k solve this issue, or would a screen have to be 16k to have a pixel free viewing experience?
