• 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.
• 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.
