Notes:
1. “Mode” denotes the computer mode determined
by the projector. The number can be read by the
read command through RS-232 interface.
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.
4. The synchronization signal widths represent the
number of dots (horizontal) and the number of
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
computer modes:
D MAC16 as SVGA75
D MAC19A as XGA60
D MAC19B as XGA75
See Setup Sub–Menu to set MAC MODE.
7. Computer name (in right column) appears when
you display the TEST SCREEN on the projector.
