There are vertical lines in my projected image. What should I do?

• If you're projecting from a computer, try pressing Auto on the remote control or Enter on the control panel. This resets the computer display settings automatically. If that doesn't work, adjust the Tracking and Sync using the buttons on the control panel. Hold down the button until your image looks correct. It is best to project a gray screen (or the Windows exit screen) when you adjust these settings. You can also change the Tracking and Sync settings through the Video menu.
