[12] [13] The concept of optimal viewing distance, [5] which is based on physics and physiology, has become essential with the advent of UHD (Ultra High Definition ...
At this distance, the individual pixels cannot be resolved while simultaneously maximizing the viewing area. For more TV resolutions, see "The optimal viewing distance". [3] [4] The TV image is composed of many lines of pixels. Ideally, the TV watcher sits far enough away from the screen that the individual lines merge into one solid image.

Dot pitch may be measured in linear units (with smaller numbers meaning higher resolution), usually millimeters (mm), or as a rate, for example, dots per inch (with a larger number meaning higher ...
where is the distance between the screen and observer (e.g. in meters), and is the absolute pixel density of the screen in pixels per unit length (e.g. in pixels per meter). Based on Jobs' statement, the threshold for a Retina display is an angular pixel density of 52–63 PPD.
