Check one of the following:
- If you're projecting from a computer, press the Auto button (on the remote control) or the Auto/Enter button (on the projector). This automatically resets the projector's tracking, sync, resolution, and position settings. See more information to adjust these settings yourself.
- You may have to adjust the Position setting if the image is slightly off-center.
- Press the Resize button on the remote control to make sure the projector is displaying at the correct resolution or aspect ratio.
- If you've connected equipment to the Computer 1, Computer 2, or BNC port, the wrong input signal setting may be selected. Select the correct setting, in the Setting menu for the type of computer or video player you've connected.
- If you're projecting from a computer, the computer may have been set for dual display. This causes the projector to display only half the image (the right or left side). Access your computer's display settings (as you would to adjust other display properties), then turn off dual display. See your computer's manual or online help for details.
- Make sure your computer's resolution setting is correct. Ideally, it should be 1024 x 768 to match the projector's native resolution. If this option isn't available, select one of the other compatible video formats listed in the User's Guide.
You also may need to modify existing presentation files if you created them for a different resolution. See your software documentation for specific information.
