HDMI Info and FAQ

WHAT IS HDMI ?
HDMI stands for (H)igh (D)efinition (M)ultimedia (I)nterface.
HDMI is currently the most prolific standard for audio/video connectivity, and has even gained traction in the computer industry.
Featuring a modern sliding contact design instead of the bulky screw-on style (like DVI and VGA), and with unallocated
pipeline to accommodate future technologies and speed increases, HDMI is attempting to finally unify all digital media
components with a single cable.
HDMI 2.0 takes advantage of this expansion to further increases the bandwith limit to 18 Gbps (from its original 5 Gbps),
to allow for higher definition 4K UltraHD video, audio, and even networking.
WHAT DOES HDMI REPLACE ?
The high bandwidth of HDMI is structured around
delivering the best quality digital video and audio. Capable of all
international frequencies and resolutions, the HDMI
cable is designed to replace all analog signals (i.e. S-Video,
Component, Composite, and Coaxial), as well as UHD and HDTV
digital signals (i.e. DVI, P & D, DFP), with
no compromise in fidelity from the source.
Additionally, HDMI is capable of carrying up to
8 channels of digital-audio, replacing the old analog
connections (RCA, 3.5mm) as well as optical
formats (SPDIF, Toslink). HDMI 2.0 added support for High Dynamic Range (HDR) video as well.
WHAT IS HDMI 2.0 ?
HDMI 2.0, released April 8th, 2015, is a superset of all previous HDMI versions, with the addition of HDR video.
HDMI 2.0 offers a higher video throughput, at 600Mhz, to
allow for 4K UHD displays, 32 channels of audio at up to 1536khz, 21:9 aspect ratio support, and dynamic audio-video synchronization.
WHAT CAN HDMI BE USED WITH ?
To function as an all-inclusive interface, HDMI
is being implemented in virtually all multimedia devices,
from HDTV's and DVD players to computers and stereo
receivers. It is compatible with DVI products and can
be converted with a simple adaptor plug.
HDMI and HDMI 1.3 are also entirely cross-compatible, and
can be easily connected with a mixed-connector cable.
WHAT FORMATS COMPETE WITH HDMI?
HDMI is already permeating the home theater market, and is on most
every HDTV, DVD player, and receiver available today. It has become
the standard for entertainment solutions, but is facing competition in the PC industry on a couple of fronts.
The open-market DisplayPort
connector, is looking to overthrow both DVI (in the computer industry) and HDMI (in
the home theater industry). It has also branched off into Mini DisplayPort.
The already-mentioned DVI, which used to be fairly ubiquitous in high-end computer hardware, has slowly been replaced by either HDMI or
Thunderbolt, another all-in-one format that carries even more type of data than HDMI, has been making inroads among media producers,
but its higher price has mostly kept it there.
