VESA Mount Adapter
VESA (), formally known as Video Electronics Standards Association, is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989To retrieve the information, search for Entity Number C1645094. and has its office in San Jose. It claims a membership of over 300 companies. In November 1988, NEC Home Electronics announced its creation of the association to develop and promote a Super VGA computer display standard as a successor to IBM's proprietary Video Graphics Array (VGA) display standard. Super VGA enabled graphics display resolutions up to 800×600 pixels, compared to VGA's maximum resolution of 640×480 pixels—a 56% increase. The organization has since issued several additional standards related to computer video displays. Widely used VESA standards include DisplayHDR, DisplayPort, and Flat Display Mounting Interface.

Standards Organization
A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary function is developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise contributing to the usefulness of technical standards to those who employ them. Such an organization works to create uniformity across producers, consumers, government agencies, and other relevant parties regarding terminology, product specifications (e.g. size, including units of measure), protocols, and more. Its goals could include ensuring that Company A's external hard drive works on Company B's computer, an individual's blood pressure measures the same with Company C's sphygmomanometer as it does with Company D's, or that all shirts that should not be ironed have the same icon (a clothes iron crossed out with an X) on the label. Most standards are voluntary in the sense that they are offered for adoption by people ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Accelerated Graphics Port
Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards. Since 2004, AGP was progressively phased out in favor of PCI Express (PCIe), which is serial, as opposed to parallel; by mid-2008, PCI Express cards dominated the market and only a few AGP models were available, with GPU manufacturers and add-in board partners eventually dropping support for the interface in favor of PCI Express. Advantages over PCI AGP is a superset of the PCI standard, designed to overcome PCI's limitations in serving the requirements of the era's high-performance graphics cards. The primary advantage of AGP is that it doesn't share the PCI bus, providing a dedicated, point-to-point pathway between the expansion slot(s) and the motherboard chipset. The direct connection also allows for higher clo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

VESA Enhanced Video Connector
The VESA Enhanced Video Connector is a VESA standard intended to reduce the number of cables around a computer by incorporating video, audio, FireWire and USB into a single cable system. The intention of the system was to make the monitor the central point of connection. Although the specific idea did not find favour with computer manufacturers, it was evolved into the somewhat more popular VESA Plug and Display standard. A VESA EVC connector is capable of carrying analog video (VGA-based) output, video input (composite), FireWire, audio (analogue stereo), and USB signals. Pinout is somewhat similar to the newer VESA Plug and Display. It can be distinguished from a Plug and Display connector by the shell, which is shaped like an isosceles trapezoid similar to the shell of a D-subminiature instead of the "D"-shaped shell of a DVI Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG).

Coordinated Video Timings
Coordinated Video Timings (CVT; ''VESA-2013-3 v1.2'') is a standard by VESA which defines the timings of the component video signal. Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions. The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity. The standard was adopted in 2002 and superseded the Generalized Timing Formula. Reduced blanking CVT timings include the necessary pauses in picture data (known as "blanking intervals") to allow CRT displays to reposition their electron beam at the end of each horizontal scan line, as well as the vertical repositioning necessary at the end of each frame. CVT also specifies a mode ("CVT-R") which significantly reduces these blanking intervals (to a period insufficient for CRT displays to work c ...

Generalized Timing Formula
Generalized Timing Formula is a standard by VESA which defines exact parameters of the component video signal for analogue VGA display interface. The video parameters defined by the standard include horizontal blanking (retrace) and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity. Unlike predefined discrete modes (VESA DMT), any mode in a range can be produced using a formula by GTF. A GTF-compliant display is expected to calculate the blanking intervals from the signal frequencies, producing a properly centered image. At the same time, a compliant graphics card is expected to use the calculation to produce a signal that will work on the display — either a GTF default formula for then-ordinary CRT displays or via a custom formula provided via EDID signaling. These parameters are used by the XFree86 Modeline, for example. This video timing standard is av ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

LC Shutter Glasses
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image. Modern active shutter 3D systems generally use liquid crystal shutter glasses (also called "LC shutter glasses" or "active shutter glasses"). Each eye's glass contains a liquid crystal layer which has the property of becoming opaque when voltage is applied, being otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately block one eye, and then the other, in synchronization with the refresh rate of the screen. The timing synchronization to the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

VESA Stereo
VESA Stereo is a liquid crystal shutter glasses interface standard by the Video Electronics Standards Association (VESA) for stereoscopic 3D displays. The system does not drive the glasses directly, instead providing a basic signal and power to be used by other electronics either inside the glasses or in an external unit. The VESA Stereo connector has been extensively used in 3D accelerators as well as 3D DLP TVs. Technical Details The stereo-sync signal changes when the system is changing between showing images for the right eye and left eye. The signal is a TTL signal where the "high" state indicates the left eye should be exposed. No special software is necessarily needed to create the stereo-sync signal as it can be created from the Vertical synchronization Analog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by amplitude, phas ...

Digital Packet Video Link
Digital Packet Video Link (DPVL) is a video standard released by VESA in 2004. Unlike previous technologies, in order to save bandwidth, only portions of the screen that are modified are sent by the means of this link. DPVL also introduces metadata Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive ... video attributes support.

VESA Display Power Management Signaling
VESA Display Power Management Signaling (or DPMS) is a standard from the VESA consortium for power management of video monitors. Example usage includes turning off, or putting the monitor into standby after a period of idle time to save power. Some commercial displays also incorporate this technology. History VESA issued DPMS 1.0 in 1993, basing their work on the United States Environmental Protection Agency's (EPA) earlier Energy Star power management specifications. Subsequent revisions were included in future VESA BIOS Extensions. Design The standard defines how to signal the H-sync and V-sync pins in a standard SVGA monitor to trigger the monitor's power saving capabilities. DPMS defines four modes: normal, standby, suspended and off. When in the "off" state, some power may still be drawn in order to power indicator lights. The standard is: Reception By the late 1990s, most new monitors implemented at least one DPMS level. DPMS does not define implementation det ...

DisplayID
DisplayID is a VESA standard for metadata describing display device capabilities to the video source. It is designed to replace E-EDID standard and EDID structure v1.4. The DisplayID standard was initially released in December 2007. Version 1.1 was released in March 2009 and was followed by version 1.2 released in August 2011. Version 1.3 was released in June 2013 and current version 2.0 was released in September 2017. DisplayID uses variable-length structures of up to 256 bytes each, which encompass all existing EDID extensions as well as new extensions for 3D displays, embedded displays, Wide Color Gamut and HDR EOTF. DisplayID format includes several blocks which describe logical parts of the display such as video interfaces, display device technology, timing details and manufacturer information. Data blocks are identified with a unique tag. The length of each block can be variable or fixed to a specific number of bytes. Only the base data block is mandatory, while all exten ...

Monitor Control Command Set
VESA Monitor Control Command Set or MCCS is a computer standard developed by Video Electronics Standards Association. It defines a binary protocol for controlling the properties of computer monitors from a host device such as PC, set-top box, etc. MCCS requires a bidirectional communication protocol like Display Data Channel between host and display, although the specification does not favour any particular protocol. Controls A ''virtual control panel'' (VCP) code is a binary code that represents a single command entity in the MCCS language. Each command contains variable number of data parameters and command attributes. The following groups of controls are defined in the standard: * Factory Preset - commands for restoring factory defaults, as well as specifically restoring color, geometry, brightness/contrast, and TV settings defaults, and storing/restoring presets. * Color Adjustment - commands that control color temperature, hue, and saturation. * Geometry Adjustment - command ...
