From my experience, yeah. 720P shouldn't be on larger than a 24-26" TV

Larger than that, and they should be using 1080P screens.

You also shouldn't be watching TV at 20 feet, unless you're in a movie theater. Then it's not TV though.

No it is, that's the problem.

See, with 1080p, you can't sit <5 feet from it, because it starts to look grainy and horrible.

So, you need a projector to thoroughly enjoy the experience.

A 120" screen from 10 feet away is almost perfect.

Use the Pythagorean Thereom to identify the a and b values of the monitor based on the 16:9 a:b ratio given c, the horizontal size of the monitor. Then identify the total amount of pixels in the entire monitor (i.e. 1920x1080=2703600 total pixels) and divide that by a(b) as derived from the above, as modeled by the equation (given that the aspect ratio is 16:9):

[horizontal length in inches(vertical length in inches)]/[(16b/9)(9a/16)]=pixel density per inch squared.

i.e. for my 23" monitor, the a and b lengths are approximately 20 and 11 inches, so my pixel density is 27036000/20(11)=~12000 though realistically using precise values it is around 9000 per inch squared.

Or just use this:
