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 to connect HDMI or DVI sources. Dual-mode is an optional feature, so not all DisplayPort sources ...
To ensure baseline compatibility between different HDMI sources and displays (as well as backward compatibility with the electrically compatible DVI standard) all HDMI devices must implement the sRGB color space at 8 bits per component. [5]: §6.2.3 Ability to use the Y′C B C R color space and higher color depths ("deep color") is optional.
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.

E-DDC Version 1.1, approved March 2004, featured support for HDMI and consumer electronics. E-DDC Version 1.2, approved December 2007, introduced support for DisplayPort (which has no dedicated DDC2B links and uses its bidirectional auxiliary channel for EDID and MCCS communication) and DisplayID standards.
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 .
DSC version 1.2 was released on 27 January 2016 and is included in version 1.4 of the DisplayPort standard; DSC version 1.2a was released on 18 January 2017. The update includes native encoding of 4:2:2 and 4:2:0 formats in six-pixel containers, 14/16 bits per color, and minor modifications to the encoding algorithm.
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 60 Hz in version 2.0 (2013).
