1. Display adjustment at the input source may be required. Adjust pixel tracking, phase and filter. Noise is
particularly common on YPbPr signals from a DVD player.

video input should be terminated at the last source input only.
3. The input signal and/or signal cables carrying the input signal may be of poor quality.
4. If the distance between the input source device and the projector is greater than 25 feet, signal amplifica-
