CRT screens display images by moving beams of electrons very quickly across the screen. Once the beam of the monitor has reached the edge of the screen, it is switched off, and the deflection circuit voltages (or currents) are returned to the values they had for the other edge of the screen; this would have the effect of retracing the screen in ...

A composite monitor must have a two-dimensional approximately flat display device with circuitry to accept a composite signal with picture and synchronisation information, process it into monochrome chrominance and luminance, or the red, green, and blue of RGB, plus synchronisation pulses, and display it on a screen, which was predominantly a ...
On two-dimensional display devices such as computer monitors the display size or viewable image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit's design. The main measurements for display devices are width, height, total ...
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 ...
CRT monitors can still outperform LCD and OLED monitors in input lag, as there is no signal processing between the CRT and the display connector of the monitor, since CRT monitors often use VGA which provides an analog signal that can be fed to a CRT directly.
Apple's manufacture history of CRT displays began in 1980, starting with the Monitor /// that was introduced alongside and matched the Apple III business computer. It was a 12″ monochrome (green) screen that could display 80×24 text characters and any type of graphics, however it suffered from a very slow phosphor refresh that resulted in a "ghosting" video effect.
The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal. It can ...
