That chart should really be zoomed to about 1/5 its size... it goes up to 150 inch? Who has displays that big?

The X axis should go from 10 to 60, the Y axis should go from 1ft to 30ft, max.

As it is, it's not all that useful for figuring out what the density limits of a desktop monitor are. (Average desktop monitor sizes occupy maybe 1/12 of the X axis!)

Well with a 4K display your able to sit closer to larger ones because you will not detect the pixels as easier. I know many people think you want more distance with a larger set, but with 4Ks they are just fine, as long as don't move your eyes to much to see the entire screen.

That is a very nice chart.

But gee, one length (viewing distance) is in different units than the other length (screen diagonal size). Hilarious.

What does "full benefits" mean?
