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.

• Althoug h the projector can display signa ls wit h reso lution 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.
