How to connect laptop to projector?


Most laptops have an HDMI port that may also be used to project to other displays. Some older systems may also have a VGA port that may be used to connect a laptop to the projector. The VGA port on a laptop consists of three rows of five holes.


Newer laptops may not have a  VGA or HDMI port. If your laptop does not have a VGA or HDMI port, you will need to purchase an adapter that allows you to connect one of these two cables to your laptop.

Next, you already got the ports mentioned above and are about to look for a cable that links the laptop and the projector. It is either HDMI to HDMI, HDMI to VGA*, VGA* to HDMI, or VGA* to VGA* cables.

Getting Started

  1. Turn on the projector system and select the appropriate HDMI mode screen.
  2. Connect the VGA or HDMI cable to your laptop's VGA or HDMI port. If you are using an HDMI or VGA adapter, plug the adapter into your laptop and connect the provided cable to the other end of the adapter.
  3. Turn on your laptop. After your desktop screen has loaded, your laptop image should project. If it does not, please follow the instructions below that pertain to your laptop's operating system.

*Please note that VGA is only for display output and did not transfer in/out audio.
