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 ...
Three distinct types of defective pixels are described: Type 1 = a hot pixel (always on, being colour white) Type 2 = a dead pixel (always off, meaning black) Type 3 = a stuck pixel (one or more sub-pixels (red, blue or green) are always on or always off) The table below shows the maximum number of allowed defects (per type) per 1 million pixels.
If you happened to watch Zack Snyder’s “Army of the Dead” this weekend, you might have noticed something was not quite right. You weren’t alone — quite a few Twitter and Reddit users ...
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.
Resolution The resolution of an LCD is expressed by the number of columns and rows of pixels (e.g., 1024×768). Each pixel is usually composed of 3 sub-pixels, a red, a green, and a blue one. Each pixel is usually composed of 3 sub-pixels, a red, a green, and a blue one.
Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect to report display lag. [citation needed]
As mentioned earlier, the insider builds of Windows 10 and later, as well as Windows Server 2016 and later, display a green screen. [26] [27] [24] Windows 10 and later (and Windows Server 2016 and later) also display an orange screen in an extremely rare case where a hardware issue with the GPU or a graphics driver problem is encountered.

Image persistence can occur as easily as having something remain unchanged on the screen in the same location for a duration of even 10 minutes, such as a web page or document. Minor cases of image persistence are generally only visible when looking at darker areas on the screen, and usually invisible to the eye during ordinary computer use.
