Some laptops only come with one USB-C™ port, so once you have added a hub, there is no extra port to plug in power. During 2014 several manufacturers introduced premium AV Receivers that include one, or multiple, HDMI 2.

To ensure non-stop operations, the fanless fin heat sink design prevents overheating and thus elevates its reliability. Linux can drive 8-channel LPCM audio over HDMI if the video card has the necessary hardware and implements the Advanced Linux Sound Architecture (ALSA). color spaces supported by previous versions, and added the ability to carry metadata defining color gamut boundaries. Blu-ray permits secondary audio decoding, whereby the disc content can tell the player to mix multiple audio sources together before final output. mm and has 29 pins, carrying six differential pairs instead of three, for use with very high-resolution displays such as WQUXGA (3840×2400).Action-packed and visually stunning scenes in films, games and in sports broadcasts are displayed without lag. A superb choice of cable for connecting LED/LCD/Plasma Digital HD and 3D televisions to Freeview, Sky or Virgin boxes, games consoles, Blu-ray and DVD players.

For FRL transmission, the limits are calculated using the capacity computation algorithm provided by the HDMI Specification.

Previously, the similar DisplayPort Alternate Mode could be used to connect to HDMI displays from USB Type-C sources, but where in that case active adapters were required to convert from DisplayPort to HDMI, HDMI Alternate Mode connects to the display natively.
