HDMI (High-Definition Multimedia Interface)
High-Definition Multimedia Interface (HDMI) is a standard/port for connecting high-definition video devices, such as computer monitors, video projectors and digital television, etc. HDMI carries high quality video and audio signals, and there is no need for separate audio cables as with VGA.
HDMI cables
The HDMI interface allows a port to send high-resolution digital video, theatre-quality sound, and device commands through a connector and down a single cable. There are several types of HDMI cable, each designed to support a video resolution and features in the HDMI specification.
HDMI ports
A single HDMI cable will carry both the video and audio signal from a device to your display. A HDMI cable is most frequently used to connect a laptop to a data projector or a television.
Higher quality
HDMI enables loss-less transmission and better quality video at low brightness scenes at higher resolutions.
HDMI bandwidth
HDMI has the ability to transport a high bandwidth of data (video, audio and now 3D and Ethernet) using a single cable. For the average consumer, the ability to connect their TV and DVD player with just one cable certainly makes setting up a home entertainment system less daunting.
Switching delays
Sometimes, blank screens can be caused due to authentication delays. There can also be screen flashing errors.
Physical cable limit
Physical cable with a bandwidth limit of 10 GB/sec (4K) is still required.
HDMI technology prevalence
Virtually every TV, AV receiver, DVR, Blu-ray Disc Player, and set-top box today comes standard with HDMI technology.
Other examples of HDMI technology
Other examples where HDMI technology is used is: game consoles, soundbars, etc.
