Step 1. Find the video output from your computer

Almost all computers have at least one video output.

  • For computers running Windows.

    • HDMI: This is a 6-sided tapered port that transmits both audio and video.
    • DisplayPort: it looks like a USB port, but it has a recessed side. It also transmits audio and video.
    • The VGA: it looks like trapezoids with holes inside. The VGA transmits the video, but you will need a separate audio cable (eg A / V cables) to transmit the sound.
  • For Macs.

    • HDMI: It is most often found on Macs manufactured between 2012 and 2016. It is also found on the back of iMac computers.
    • Thunderbolt 3 (also known as “USB C”). It is found on the side of modern MacBooks. You can't directly connect a USB C cable to a TV, but you can buy a USB C to HDMI adapter.
