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 - comm ...

Video Electronics Standards Association
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.

Computer Monitors
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 File:2010s collage v21.png, From top left, clockwise: Anti-government protests called the Arab Spring arose in 2010–2011, and as a result, many governments were overthrown, including when Libyan dictator Muammar Gaddafi was killed; Crimea is an ... replaced cold-cathode fluorescent lamp, CCFL Backlight, backlit LCDs. Before the mid-2000s, most monitors used a cathode-ray tube, CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, Digital Visual Interface, DVI, VGA connector, VGA, or other proprietary connectors and signals. Originally, computer monitors were used for data processing while television sets were used for video. From t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Display Data Channel
The Display Data Channel, or 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. Like modern analog VGA connectors, the DVI and DisplayPort connectors include pins for DDC, but DisplayPort only supports DDC within its optional Dual-Mode DP ( DP++) feature in DVI/HDMI mode. The standard was created by the Video Electronics Standards Association (VESA). Overview The DDC suite of standards aims to provide Plug and Play and DPMS power management experiences for computer displays. DDC1 and DDC2B/Ab/B+/Bi protocols are a physical link between a monitor and a video card, which was originally carried on either two or three pins in a 15-pin analog VGA connector. Extended display identification data (EDID) is a companion standard; it defines a compact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 video attributes support. The DPVL standard is aimed at mobile and wireless Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The mos ... hardware. References * VESA-2004-4 DPVL Standard 1.0 June 2004 External links VESA-2004-4 1.0 standard summary Computer standards VESA {{Standard-stub ...

Computer Display Standards
Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors and monitors. History Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels), color depth (measured in bits per pixel), and refresh rate (expressed in hertz). Associated with the screen resolution and refresh rate is a display adapter. Earlier display adapters were simple frame-buffers, but later display standards also specified a more extensive set of display functions and software controlled interface. Beyond display modes, the VESA industry organization has defined several standards related to power management and device identification, while ergonomics standards are set by the ...
