DisplayPort connector A DisplayPort port (top right) on a laptop from 2010, near an Ethernet port (center) and a USB port (bottom right). DisplayPort (DP) is a proprietary [a] digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).
Four times the resolution of 1080p. Requires a dual-link DVI, category 2 (high-speed) HDMI, DisplayPort or a single Thunderbolt link, and a reduced scan rate (up to 30 Hz); a DisplayPort 1.2 connection can support this resolution at 60 Hz, or 30 Hz in stereoscopic 3D. 3840×2160 (8,294k) 3840 2160 8,294,400 16:9 24 bpp DCI 4K
Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1]
It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data. DisplayPort is backward compatible with other interfaces such as HDMI and DVI through the use of active or passive adapters. Male Mini DisplayPort plug Mini DisplayPort
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.
Version 2 (as defined in 861-A) added the capability to designate a number of DTDs as "native" (i.e., matching the resolution of the display) and also included some "basic discovery" functionality for whether the display device contains support for "basic audio", YC B C R pixel formats, and underscan.

On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
