Close-up of an LCD, showing a dead green subpixel as a black rectangle. A defective pixel or a dead pixel is a pixel on a liquid crystal display (LCD) that is not functioning properly. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels, [1] while hardware companies tend to have further distinguishing ...
The signals from multiple lines are overlaid, showing shaded areas instead of a single curve. A scan line (also scanline) is one line, or row, in a raster scanning pattern, such as a line of video on a cathode-ray tube (CRT) display of a television set or computer monitor. [1]
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by ...
Motion blur, refers to the reduction in clarity when people track moving objects on a display.This is the result of the display not showing the frame for an infinitesimally short amount of time: your eyes are "tracking" an object that is in fact stationary, resulting in it looking smeared/blurry.
In past years, certainly up to the late 1960s, cue marks were applied to the composited camera original negative, but no longer. Cue marks are now applied to the printing internegative, only, and these marks appear to be black, because the mark is made on a negative image, suitable for release print making, only.

Hence the picture will have thin black bars down each side. 704 is the nearest mod(16) value to the actual analogue line lengths, and avoids having black bars down each side. The use of 704 can be further justified as follows: 625-line analogue video contains 575 active video lines [14] (this includes two half lines). When the half lines are ...
Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.
