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.
The name is very similar to the DisplayPort display interface, which was approved by VESA earlier that year. DisplayLink launched its first semiconductor product family, the DL-120 and DL-160 USB 2.0 graphics devices, in January 2007, [10] signaling a change in the company's business plan from FPGA-based systems to semiconductors. The DL-120 ...
DisplayPort Dual-Mode (DP++), also called Dual-Mode DisplayPort, is a standard which allows DisplayPort sources to use simple passive adapters to connect to HDMI or DVI displays, and allows DisplayPort displays to use simple passive adapters co connect HDMI or DVI sources. Dual-mode is an optional feature, so not all DisplayPort sources ...
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
A USB-C multiport adapter converts the device's native video stream to DisplayPort/HDMI/VGA, allowing it to be displayed on an external display, such as a television set or computer monitor. It is also used on USB-C docks designed to connect a device to a power source, external display, USB hub, and optional extra (such as a network port) with ...
DisplayPort displays use one TMDS/DisplayPort transmitter and no clock signal. An active DisplayPort adapter can convert a DisplayPort signal to another type of signal—like VGA, single-link DVI, or dual-link DVI; or HDMI if more than two non-DisplayPort displays must be connected to a Radeon HD 5000 series graphics card.

The DisplayPort website states that DisplayPort is expected to complement HDMI, [202] but as of 2016 100% of HD and UHD TVs had HDMI connectivity. [203] 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.
SlimPort is a proprietary alternative to MHL, based on the DisplayPort standard integrated into common Micro-USB ports, and supports up to 1080p60 or 1080p30 with 3D content over HDMI 1.4 (up to 5.4 Gbit/s of bandwidth), in addition to support for DVI, VGA (up to 1920 × 1080 at 60 Hz), and DisplayPort.
