Guess my vision doesn't. Simple test on my laptop 15.4" 1080p laptop screen. I can tell that 1080p is sharper than 540p at 1m distance. Can't tell the difference at 2m, let alone 3m.
540p created by downsampling to 960x270, then pixels quadrupled back to 1920x540.
Top left, bottom right are at full res, Bottom left and top right are at half res. (Obviously open full screen, it all looks identical at 960x540)
But true the old chart is too conservative, this new one is a bit over the top.
