If the image is not square, adjust the keystone using the buttons on the keypad. Press the upper Keystone button to reduce the width of the upper portion of the image, and press the lower Keystone button to reduce the width of the lower portion.

The Contrast, Brightness, Color, and Tint are factory calibrated to D65 colors, but you can adjust these settings in the Picture menu if necessary.

Connecting to a computer

Connect either a VESA cable or M1 cable into the appropriate connector on the projector. Connect the other end to the video port on your computer. If you are using a desktop computer, you first need to disconnect the monitor cable from the computer’s video port.

You can control the projector from an LCD control panel or computer by connecting a RS-232 cable to the projector’s Serial connector. Specific RS-232 commands can be found in the Appendix.
