Specify the laptop’s video output options. Most laptops have a display connection port on the back of the body, but some also have this port on the side wall. Some of the main connection ports on laptops are:

  • Windows :
    • HDMI – The port has two beveled corners that form six sides, approximately 1cm wide and available on most Windows laptops
    • DisplayPort – Similar to HDMI, but with a beveled corner, and the rest of the corners are right angles.
    • VGA or DVI – The VGA port is color with 15 holes, while the DVI port is usually black or white with 24 holes and a blank edge. These ports are often found on older computers.
  • Mac :
    • Thunderbpt 3 (also known as USB-C ) – The oval port on the sidewall of most newer MacBooks.
    • HDMI – The port with two beveled corners forming the hexagon is found on some MacBooks.
    • Mini DisplayPort – A hexagonal port found on Macs manufactured between 2008 and 2016.

Attach the other end of the cable to the monitor. Place the other end of the video connection cable into the port on the TV to fit and attach.

  • If the external monitor is equipped with another connector, you will need an adapter cable to connect it to the monitor. Some converters are just a bridge between two types of cables. For example, a VGA to HDMI converter gives you one VGA connector and one HDMI connector. Some popular conversion cables are as follows:
    • HDMI to DisplayPort.
    • DisplayPort (or Mini DisplayPort) to HDMI.
    • Mini DisplayPort to DisplayPort.
    • USB-C to HDMI (or DisplayPort).
    • VGA to HDMI.
    • DVI to HDMI.

    Extend the Mac desktop if needed. If you want to use the external display as an extension of the Mac display (such as the right side of the Mac display), click the Arrangement tab at the top of the window and uncheck the “Mirror Displays” box ” (Screen mirroring) below the screen layout window.

    • You can also adjust the position of the menu bar here by clicking and dragging the white rectangle at the top of the screen layout window left or right.
  • Advice

    • DisplayPort, HDMI, and USB-C ports can all carry audio, which means the monitor’s speakers can pass the laptop’s audio output if you use one of these connections.
    • If you use an older video cable, you may not be able to hear the sound on the TV. You can stream audio to external speakers using the headphone port on your laptop. Use the 3.5mm aux cable to connect to the headphone port. Use an adapter to connect to speakers or an audio input, if necessary.
    • You can update your computer’s drivers to improve screen finding and the quality of the connected display.

    Warning

    • If the screen does not display the contents of the laptop, you may have used the wrong cable. Try connecting with a different cable or use a different connector if possible.
