Screen burn-in. 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.
Close-up of an LCD, showing a dead green subpixel as a black rectangle. A defective 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 types.
TFT display showing persistence artifacts Detail of a TFT display showing whole screen persistence artifacts Image persistence on a BenQ GW2765HT IPS LCD monitor. Image persistence, or image retention, is the LCD and plasma display equivalent of screen burn-in. Unlike screen burn, the effects are usually temporary and often not visible without ...
This bit of marketing obfuscation is calculated as horizontal resolution × vertical resolution × 3. For example: 640 × 480 VGA is 921,600 subpixels, or 307,200 pixels, 800 × 600 SVGA is 1,440,000 subpixels, or 480,000 pixels, and 1024 × 768 XGA is 2,359,296 subpixels, but only 786,432 full-color pixels. ^ Apple Computer 1 megapixel standard.
Monochrome monitor. A monochrome monitor is a type of computer monitor in which computer text and images are displayed in varying tones of only one color, as opposed to a color monitor that can display text and images in multiple colors. They were very common in the early days of computing, from the 1960s through the 1980s, before color ...
Screen tearing[1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [2] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate. That can be caused by non-matching refresh rates, and the tear line then moves as the phase ...
The drawing on the upper right shows a moiré pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines. [4]
A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL ...
