Notes:
1. “Mode” denotes the computer mode determined
by the projector. The number can be read by the

2. Advanced scaling is used for all inputs that are
not 800 x 600.
3. Mode 10 and 140: For XGA, full advanced
scaling (vertical and horizontal) is used.
Modes 11–13 and 14: Only vertical advanced
scaling is used.
Modes 11–13 and 14: Only vertical advanced
scaling is used.
4. The synchronization signal widths represent the
number of dots (horizontal) and the number of
lines (vertical).
lines (vertical).
5. H-size denotes the standard number of dots in
the horizontal period.
6. For the MAC16 and MAC19A/B computers, you
must manually set the MAC MODE to “ON” to
determine the correct modes.
Set the MAC MODE to “OFF” for the following
