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.
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: Proposed alternative to HDMI, used with computer displays: (VGA, DVI) Apple Inc.'s successor to their own Mini-DVI.
The following is a list of the most commonly used HDMI-CEC commands: One Touch Play allows devices to switch the TV to use it as the active source when playback starts; System Standby enables users to switch multiple devices to standby mode with the press of one button; Preset Transfer transfers the tuner channel setup to another TV set
The USB video device class (also USB video class or UVC) is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras.
Miracast is "effectively a wireless HDMI cable, copying everything from one screen to another using the H.264 codec and its own digital rights management (DRM) layer emulating the HDMI system". The Wi-Fi Alliance suggested that Miracast could also be used by a set-top box wanting to stream content to a TV or tablet.
From the computer user's perspective, the USB interface improves ease of use in several ways: The USB interface is self-configuring, eliminating the need for the user to adjust the device's settings for speed or data format, or configure interrupts, input/output addresses, or direct memory access channels.

For example, Micro-USB and HDMI Type-A support one A/V lane, USB Type-C supports up to four A/V lanes, and the superMHL connector supports up to six A/V lanes (36 Gbit/s). In addition to supporting a variable number of lanes, the specification supports VESA Display Stream Compression (DSC) 1.1, a "visually lossless" (but mathematically lossy ...
A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common. Originally computer monitors were used for data processing while television sets were used for video.
