• The brightness level of the projected image will change accordingly when you switch between different
input signals.
• For best display picture results, you should select and use an input signal which outputs at the
projector’s native resolution. Any other resolutions will be scaled by the projector depending upon the
“aspect ratio” setting, which may cause some image distortion or loss of picture clarity. See
