However, to stream music and movies to a non-certified device, Miracast adapters are available that plug into HDMI or USB ports. [21] Certification does not mandate a maximum latency (i.e. the time between the display of pictures on the source and display of the mirrored image on the sync display).
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.
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]
An HDMI port on the side of a laptop computer. Some tablet computers implement HDMI using Micro-HDMI (type D) port, while others like the Eee Pad Transformer implement the standard using mini-HDMI (type C) ports. All iPad models have a special A/V adapter that converts Apple's Lightning connector to a standard HDMI (type A

A Chromecast stick plugged into the HDMI port of a TV. The cable attached to the other end is the USB power supply. In the mid-to-late 2010s, the dongle form factor was extended to digital media players with a small, stick-like form factor—such as Chromecast and Fire TV Stick—that are designed to plug directly into an HDMI port on a television or AV receiver (powered via Micro USB ...
CEC [3] is a separate electrical signal from the other HDMI signals. This allows a device to disable its high-speed HDMI circuitry in sleep mode, but be woken up by CEC. It is a single shared bus, which is directly connected between all HDMI ports on a device, so it can flow through a device which is completely powered off (not just asleep).
Although MHL ports can be dedicated to MHL alone, the standard is designed to permit port sharing with the most commonly used ports.) The USB port switches from USB to MHL when it recognizes an MHL-qualified sink (e.g., a TV) detected on the control wire. A typical MHL sink will be shared with HDMI on a standard 19-pin HDMI receptacle.
