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).
DisplayPort is a digital display interface standard (approved May 2006, current version 1.4 published on March 1, 2016). It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.
In October 2011 Toshiba announced the REGZA 55x3, [48] which is claimed to be the first 4K glasses-free 3D TV. DisplayPort supports 3840 × 2160 at 30 Hz in version 1.1 and added support for up to 75 Hz in version 1.2 (2009) and 120 Hz in version 1.3 (2014), [49] while HDMI added support for 3840 × 2160 at 30 Hz in version 1.4 (2009) [50] and ...
The data is transmitted via the cable connecting the display and the graphics card; VGA, DVI, DisplayPort and HDMI are supported. [ citation needed ] The EDID is often stored in the monitor in the firmware chip called serial EEPROM (electrically erasable programmable read-only memory) and is accessible via the I²C-bus at address 0x50 .
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
DisplayPort is royalty-free, though patent pool administrator Via LA attempts to collect a $0.20 per-device charge for a bulk license to patents it regards as essential to the DisplayPort specification, [218] while HDMI has an annual fee of US$10,000 and a per unit royalty rate of between $0.04 and $0.15.
[18] [19] They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity".
A widely used de facto standard, introduced with XGA-2 and other early "multiscan" graphics cards and monitors, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1. 3:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with ...
