Connecting a Computer
The projector ships with an analog VESA computer cable. If your computer has a digital output,
you can order the optional digital M1 computer cable. Using a digital source generates the
highest quality and brightest image possible.
1. Plug one end of the computer cable into the PC 2 connector on the projector.
NOTE:
Many laptop computers do not automatically turn on their external video port when a secondary
display device such as a projector is connected. Refer to your computer manual for the command that
activates the external video port. Activation commands for some laptop computers are listed in the
Service section of our website.
2. Plug the other end of the computer cable into the video connector on your computer. If you are
using a desktop computer, you need to disconnect your monitor cable from your computer
first.
