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.
Various general commands such as display orientation, degauss, gamma, zoom, focus, brightness/contrast, backlight control, etc. [a] It is possible to select the input source using a VCP command. Some monitors will only take VCP commands from the active input source, others will take commands from any connected input source.
Daisy-chaining is a feature that must be specifically supported by each intermediary display; not all DisplayPort 1.2 devices support it. Daisy-chaining requires a dedicated DisplayPort output port on the display. Standard DisplayPort input ports found on most displays cannot be used as a daisy-chain output. Only the last display in the daisy ...
Apple Inc. Lenovo, HP, and Dell systems and monitors ATI RV670 based graphics cards and NVIDIA G92 graphics cards (both as OEM optional implementations) DisplayPort introduced the 128-bit AES to replace HDCP. DisplayPort version 1.1 added support for HDCP. DiiVA: 2008: 13-pin Digital: 2560 × 1600 @ 75 4096 × 2160 @ 24: A/V systems
The DisplayPort website states that DisplayPort is expected to complement HDMI, [203] but as of 2016 100% of HD and UHD TVs had HDMI connectivity. [204] DisplayPort supported some advanced features which are useful for multimedia content creators and gamers (e.g., 5K, Adaptive-Sync), which was the reason most GPUs have DisplayPort.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
The monitor only supported DisplayPort version 1.2, which is limited to 5120 × 2880 at 30 Hz. To work around this, the UP2715K implemented a system by which the bandwidth of two DisplayPort connections could be combined to achieve 60 Hz, using a picture-by-picture mode to virtually treat the display as two smaller 2560 × 2880 monitors side-by ...
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 replaced CCFL ...
