HDMI (High-Definition Multimedia Interface)?

It's a media cable that allows you to connect high definition devices together (ie. blue ray player to HDTV)

The advantages over other cables: It can transmit High definition signals. It allows devices to send other information to each other (as an example, my TV sends it's ideal resolution to my xbox so the xbox can change it's display settings accordingly, and in return my xbox can send it's colour profile to my TV so the TV can display the picture as it was meant to be seen.)

When you turn on your devices it will take a few seconds for a connection to be made. During this time, devices are "talking" to each other and establishing a connection. It works more like a network connection (where data is send) than your normal tv connection.

If your devices have HDMI ports then I strongly recommend using it. Picture quality is very much enhanced when viewing high definition content.

It would not "MAGICALLY rework" Low Def to hi Def alerts..... The Video recording, the television station, the Reciever Sat, and all the bins to transform the sign might desire to be extreme DEFINITION contraptions...... If one unit is LOW DEF.....you basically get Low Def..... And merely by using fact HDMI provides you the suitable HD sign on your television set, would not advise this is all HD....there is lots extra low def channels waiting till the final minute to bypass HD..... So get a GRIP....

in a few letters, it describes a factory made piece of wire that connects two or electronic components with all of the necessary connections needed for operations, and no individual independant wires to mess around with. what it does is eliminate cross wiring and later trouble shooting trying to figure out why something does not work, the the rest is majic
