NOTE • Be sure to check jack type, signal level, timing and resolution before connecting this projector
to a PC.
• Some PCs may have multiple display screen modes. Use of some of these modes will not be possible with
this projector.
• Depending on the input signal, full-size display may not be possible in some cases. Refer to the number of
display pixels above.
• Although the projector can display signals with resolution up to UXGA (1600x1200), the signal will be
converted to the projector's panel resolution before being displayed. The best display performance will be
achieved if the resolutions of the input signal and projector panel are identical.
• Automatic adjustment may not function correctly with some input signals.
• The image may not be displayed correctly when the input sync signal is a composite sync or a sync on G.
• The illustrations in this manual are for illustrative purposes. They may differ slightly from your projector.
