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.
• Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
• Adjust the Sharpness setting to improve image quality.
• If you are projecting from a computer, 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, use a lower resolution.

Solutions When the Image Brightness or Colors are Incorrect
If the projected image is too dark or light, or the colors are incorrect, try the following solutions:
• Press the Color Mode button on the remote control to try different color modes for the image and
environment.
• Adjust the available settings on the Image menu for the current input source, such as Brightness ,
Contrast , Tint , Color Adjustment , and/or Color Saturation .
• Make sure you selected the correct Input Signal or Video Signal setting on the Signal menu, if
available for your image source.
• Make sure all the cables are securely connected to the projector and your video device. If you
connected long cables, try connecting shorter cables.
• If you are using the ECO Power Consumption setting, try selecting Normal in the Settings menu.
• If the image has been progressively darkening, you may need to replace the projector lamp soon.
