Uh, you're clearly confused. Human vision doesn't work the way you describe; screen size is irrelevant, it's distance from the eye that determines how small the pixel can be resolved.

Um, no. Screen size means everything, and the ability for an eye to resolve something is a function of it's size and it's distance. Not just one over the other.

I've asserted that the difference between your 10" and 21" distances isn't the significant factor, and I stand behind that.

Turn the resolution down on your 24" display from 1920x1080 to 1280x800 and tell me that "screen size doesn't matter."

Likewise, turn your 400dpi screen down to 200dpi on your 5" phone and try to tell me it makes any functional difference at all.

You've lost the plot.

Are you sure you aren't confused?


You've just increased the pixel size by 50% (assuming you meant 1920x1200 -> 1280x800). You can't make the screen size smaller, but you can definitely make the pixel size larger, which is exactly what I said:

20/20 vision means you can resolve 1/16" at 20 ft, or a pixel at 300dpi at 10".

The difference between 400dpi and 200dpi is approximately the same as moving your phone closer by half (5" to my eye!) I can absolutely see the difference. Are you saying you can't see the difference between a phone held up at 10" and a phone held up at 5"?

Once you bring an iPhone up to 5", you should be able to see the pixels, meaning your point is wrong; there is in fact a functional difference between 200dpi and 400dpi.

You've made my point for me.

On a large screen at 21" (to use your specs), DPI is *very* important.

On a phone, your variance of 11" from a 5" screen to a 24" screen isn't nearly as important as the pixel density. You're messing with the wrong variable.

And since no one uses a phone at 5" from their face, what difference does it make if you can see the pixels at that distance? You call that a "functional" difference? Only if you're horrifically short-sighted.

Your point would be made if you also said a 24" 4k monitor is pointless being that it is geometrically equivalent.

My point is that the difference between 400 dpi to 200 dpi is as big a change on a 5" screen as 200dpi to 100dpi on a 24" screen.

If you can see the difference on a 24" screen, you can see the difference on a 5" screen.

Apparent screen size, for example, is identical between a 24" screen at 4 feet and a 5" screen at 1 foot. Those are the distances where you can no longer "resolve" a pixel on a 1080p display.

Now while you don't normally hold a phone much farther or closer than 1', you definitely sit closer to your 24" display than 4', which means 1080p is woefully underspecced.

To get a similar "quality of life" out of a 24" display, you would need about a 4k monitor.

Are you going to now argue that you cannot visually appreciate a 4k 24" monitor? Because that is the "equivalent" geometry to a 5" 1080p screen which you say is pointless.

Me, as I've directly measured, can clearly see the pixels on a bog standard 1920x1200 24" display and can also clearly appreciate a 3840 x 2160 4k resolution.
