As mentioned in our last Tek Tip regarding multiple monitors, when it comes to display set ups there are a plethora of connections and cables to get the job done.  Whether you are configuring a basic visual or have more specific needs such as audio and high resolution, there’s a cable for it. With so many options, how do you keep track of the differences?






Let’s break down the 6 most commonly used video cables.


  • HDMI
    • Stands for High-Definition Multimedia Interface and is one of the most common video connections. It is a one cable solution used for video and audio connections. They are available in 5 shapes, though the common three are Type A, Type C, and Type D.
  • DisplayPort
    • More common on PC’s then TV’s, this connection provides high-definition video and most times audio. It has the ability to output multiple displays and has advantages regarding screen refresh rates.
  • DVI
    •  The Digital Visual Interface cable only supports video and is typically for older systems. It is commonly found on PC monitors and consists of three different types of cables, each carrying varying bandwidth.
  • VGA
    • A Video Graphics Array cable is also known as an RGB connection. VGA has been around for decades and only supports video. This cable has trouble obtaining higher resolutions.
  • USB-C
    • Released in 2016 by Apple, USB-C replaced their previous laptop connections. It is a fully reversable plug with cross-platform compatibility. It can transmit audio, data, power and output Video.
  • Mini Display Port
    • A less common and miniature version of a DisplayPort. This cable lacks the upgrades that other modern cable types have, though it is still able to display the same resolution as a DisplayPort.

If you find the necessary ports are not available on your device, you can invest in a Docking Station that adds more peripherals to your computer therefore allowing for more ports.
