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 types.
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.
In February 2009, Asus unveiled the 1000HE, using the new Intel Atom 280 processor, with a 10-inch LED-lit display at 1024x600 physical but 1024x768 virtual, 6-cell battery with an advertised 9.5 hours of battery life, 160 GB HDD running at 5400RPM, Bluetooth, 802.11n wireless networking, 1.3-megapixel camera, and revised keyboard similar to ...
During the POST, the BIOS must integrate multiple competing, changing, and even mutually exclusive standards and initiatives for the matrix of hardware and operating systems the PC is expected to support, although at most only simple memory tests and the setup screen are displayed.
Frame grabbers may be used in security applications. For example, when a potential breach of security is detected, a frame grabber captures an image or a sequence of images, and then the images are transmitted across a digital network where they are recorded and viewed by security personnel.
Camera monitor at a sports event. A camera monitor (or external monitor) is a monitor that attaches externally to a digital camera to aid with photography and cinematography. [1] Camera monitors typically have larger displays than the built-in monitors on consumer cameras, and are also usually brighter and able to reproduce color better.
Too much latency causes the monitor to overtake the software on occasion, leading to rendering artifacts, tearing, etc. Demo software on classic systems such as the Commodore 64 and ZX Spectrum frequently exploited those techniques because of the predictable nature of their respective video systems to achieve effects that might otherwise be ...
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
