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 ...
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 ...
Sometimes, you may get a black, green or distorted screen while playing a video on AOL Video. The quality of the video clip you are watching depends on the following two factors: The speed of your internet connection; The bit rate (speed) of the video clip
The bytes that comprise the Apple II high-resolution screen buffer contain seven visible bits (each corresponding directly to a pixel) and a flag bit used to select between purple/green or blue/orange color sets. Each pixel, since it is represented by a single bit, is either on or off; there are no bits within the pixel itself for specifying ...
That is, they have a fixed grid of pixels on the screen that show the image sharpest when running at the native resolution (so nothing has to be scaled full-size which blurs the image). In order to display non-native resolutions, such displays must use video scalers, which are built into most modern monitors. As an example, a display that has a ...
Some camcorders and digital microscopes employ separate color channel sensors (usually RGB = red, green, blue) sensors.. Pixel shifting may be implemented for one or more of these sensors by moving such a sensor by a fraction of a pixel (or even a whole pixel value) in both x- and y-direction.
Detail of a TFT display showing whole screen persistence artifacts TFT display showing persistence artifacts Image persistence on a BenQ GW2765HT IPS LCD monitor. Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display.
The screen-door effect (SDE) is a visual artifact of displays, where the fine lines separating pixels (or subpixels) become visible in the displayed image. This can be seen in digital projector images and regular displays under magnification or at close range, but the increases in display resolutions have made this much less significant.
