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.
USB-C connectors can transmit DisplayPort video to docks and displays using standard USB type-C cables or type-C to DisplayPort cables and adapters; USB-C also supports HDMI adapters that actively convert from DisplayPort to HDMI 1.4 or 2.0. DisplayPort Alternate Mode for USB type-C specification was published in 2015. USB type-C chipsets are ...
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 .
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 ...
[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".
[5] [6] [7] For example, the device cannot be designed to copy; it must "frustrate attempts to defeat the content protection requirements"; [7] it must not transmit high definition protected video to non-HDCP receivers; and DVD-Audio works can be played only at CD-audio quality [7] by non-HDCP digital audio outputs (analog audio outputs have no ...
Unified Display Interface (UDI) was a digital video interface specification released in 2006 which was based on Digital Visual Interface (DVI). It was intended to be a lower cost implementation while providing compatibility with existing High-Definition Multimedia Interface (HDMI) and DVI displays.
Basic LVDS circuit. FPD-Link was the first large-scale application of the low-voltage differential signaling (LVDS) standard. National Semiconductor immediately provided interoperability specifications for the FPD-Link technology in order to promote it as a free and open standard, and thus other IC suppliers were able to copy it.
