The display device screen should have sufficient resolution so users can distinguish all display elements,
characters, images, and codes from the maximum viewing distance and angle.
Additional Information: One measure of display resolution is the number of pixels along the width and height of the visual display screen (e.g., 1024x600). For a given viewing distance, the more pixels along each dimension, the better the display screen resolution. For image and video displays, the screen resolution should be a minimum of 32 pixels per degree of visual angle. The modulation transfer function area (MTFA) is a more accurate measure of display screen resolution; it should be a minimum of 5. This value may be directly developed from microphotometric measurements; or, for monochrome visual displays, it may be estimated using a formula, which may be found in the cited reference. See IDMS (2012) for measurement information.5908, 3001
