Tech Terms Explained - HDMI

This is the 2nd post in a series called Tech Terms Explained. It is my goal to help you gain a better understanding of the various tech terms that you may come across.

High-Definition Multimedia Interface (HDMI) is a digital interface for transmitting audio and video in a single cable.

Most high-definition televisions support HDMI. Numerous devices that plug in to your high-definition television also support HDMI.

Devices that have HDMI include:

  • Some DVD players
  • Some Cable/Satellite boxes
  • Some computers
  • Blu-Ray players
  • Apple TV
  • Roku
  • Xbox 360
  • Playstation 3

Below you see a picture of a HDMI cable. Both ends of the cable are identical so it does not matter which end you plug into your high-definition television and which end you plug into your device.


My hope is that the following advice saves you money in the future!

No matter what, though, there is absolutely no picture or sound quality difference between a $3.50 cable and a $1,000 cable.

Don't allow a salesperson to talk you into purchasing an expensive "premium" HDMI cable. This is where places like Best Buy make a ton of their profit. I would recommend the AmazonBasics High-Speed HDMI Cable that cost a little less that $6. I have purchased numerous of these for myself and others and have never had a problem.
