But the increased picture detail improvement effected by the increased pixel density is not lost by those viewing from greater distances either. In fact significant image enhancement is noticeable as much as ten times the picture height from the display (assuming 20/20 visual acuity). To the normal human eye, the roll-off of the image improvement relative to distance is, of course, gradual and dependent on a number of image variables such as contrast, brightness motion content, etc.
