At a comfortable viewing distance (i.e. one where the screen comfortably fits within, but nearly fills, your field of view), your eyes plain and simply cannot resolve a single 4K pixel, never mind at 8K. We don’t have enough angular resolution to do so. This page explains the problem nicely. To tell apart two pixels on an 82” 8K display, you’d have to be sitting just 28” from the screen, just a bit more than arm’s length! I can’t even sit that close to my 42” TV for very long. 8K really only makes sense when you want to come close and inspect some part of the screen. Perfect human vision simply doesn’t have enough resolution to make use of it from afar. When you consider that a typical TV is somewhere on the order of 10 feet (120 inches) from the viewer, it becomes clear that 8k is laughably unnecessary even on an 85” TV or 120” projection screen.

A debate along these lines was had with people arguing that 5K+ monitors make sense.  I said it is only the case if on a current monitor this checkerboard pattern:

is visible as a discrete array of pixels, rather than a solid grey colour.

For me, 1080p was clearly discernable, but at 2' viewing distance it's a solid colour on my 4K monitor.  So the real world upper limit is probably somewhere around 3K for my setup.  I don't have an unusual setup and I have normal vision (20/20) without correction.

I still stand by this, though others seem convinced that additional pixels beyond the eye's effective resolution carry a benefit.

Setting the scaling on software simply draws the interface larger, to compensate for the higher resolution. Suppose the dimensions of a character such as the letter o is 10 pixels by 10 at 100%. If the scaling is set to 150%, then it will draw the letter o at 15 by 15 pixels.

I see an array of discreet pixels on my 4K. Viewing distance is 32".

Isn't that what stuff like Cleartype is all about? They draw at the 15x15 virtual scale and map that to the 10x10 actual pixels.

My recollection was that Cleartype used subpixels, I never cared enough to look into the details though.
