• Clean the projection window.
Note: To avoid condensation on the lens after bringing the projector in from a cold environment, let the
projector warm up to room temperature before using it.
• Position the projector close enough to the screen, and directly in front of it.
• Verify that the throw distance from the projector to your projection surface meets the specifications in
your projector's Installation Guide.

• Adjust the Sharpness setting to improve image quality.
• If you are projecting from a computer using a VGA cable, press the Auto button on the remote control
to automatically adjust the tracking and sync. If any bands or overall blurriness remain, display a
uniformly patterned image on the screen and manually adjust the Tracking and Sync settings.
• If you are projecting from a computer, adjust the computer's resolution to match the projector's native
resolution, if possible.
• Reset the keystone, Quick Corner, and Arc Correction settings to their factory defaults and refocus
the image.
Note: If the projector is mounted on the wall, always use the adjustment dials on the mount to center
the image.
• Make sure the screen is flat.
