I have a 100dpi/40dpcm monitor at ~50cm in front of me. It is a 24inch/60cm monitor and I already don't really "notice" the borders of the screen at this distance (aka I have to significantly move my eyes to move my center of vision), but the more important thing is: I don't really notice the pixels while the 3D worlds and objects are moving, and to make it even better I can use some inexpensive anti-aliasing. Aren't the dpi/dpcm of "normal" 4k monitors hardly better ? And that said, I could push away my monitor to 70cm, that to embrace the whole screen in my center of vision and the pixels would be even less noticeable. I may only have to increase the font size. That's why instead of 4k, games should have a set of optimized and tested font sizes to choose from :)
