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, use a lower resolution.
• Check the resolution of your video source. If you are projecting from a standard definition video
source, your image will not be as clear as an HD (720p/1080i/1080p) video source.
• Turn off any keystone correction and disable the
Quick Corner
setting.
