You vs the Guy She Tells You Not to Worry About

Banana for scale but, also, the desk is 6' long and the little monitor is 43" (and will be re-purposed elsewhere).
Only too short of a viewing distance.
Yup, that TV is going to look like shit from a monitor distance. I honestly wouldnt go above 32" unless it's an ultra wide, or you're legally blind.
My viewing distance is 36" to the center of the screen and the pixel pitch is only 0.66 arc minutes, or about 1.5x the resolution of 20/20 vision. My vision is (corrected) slightly better than 20/20 and I can't see pixels from where I sit. I can see jaggies in single pixel lines which aren't dithered (i.e. AutoCAD), but I have to look for them. 8K may be useless for couches, but on a monitor it's pretty fucking glorious.
