This is COMPLETELY FALSE.
I am too tired right now to do the math for you but it's simple.
1/ For a 21inch screen the optimal viewing distance is 0.9 meter
2/ DPI at 720p is 69.93 and at 1080p it's 104.9
3/ The human eye resolution power is 3 minutes of arc
Do the maths
And 3 minutes of arc is ob the VERY LOW END, a normal eye have a resolution power of 1 minute
