Types Of Wired Connection

Because there are so many different types of display ports, you should make sure that the video port on your laptop or PC matches a video port on your projector. If not, you have to use a video output adapter cable that can convert one type of video signal to another.

Likely, most new projectors have one or two of the following connections:

  • HDMI – Standard HDMI transfers video and audio
  • Display Port – DisplayPort to HDMI cable, it includes video and audio
  • Mini HDMI – Mini HDMI to HDMI cable, it transfers video and audio
  • VGA – Transfers only video via VGA cable
  • DVI – Transfers only video via DVI cable
  • USB Display Adapter – The adapter converts the video signal from the USB port to HDMI or VGA.


You can easily connect your projector to a PC or laptop through any of these wired methods. Just insert one end of the cable into the laptop and the other into your projector.
