Note 3: When composite sync or sync-on- green signal is supplied, horizontal frequency must be 31 kHz or

higher.
Note 4: Sync signal :	Horizontal	Positive or Negative.	Minimum H. sync width : 1µS
	Vertical	Positive or Negative.	Minimum V. sync width : 2H

ACCEPTABLE RGB INPUT SIGNAL TIMING

Following are acceptable RGB input signal timings which have been tested by Toshiba. These are timings checked on the RGB input terminals of projection unit. If signal supplied is not exactly the same as one of the followings but is simile to one, it may be accepted by adjustment of projection unit.

When picture caused horizontal jitter or display position difference, adjust the projection unit with optional controller. However, when signal cable used or other factors have problems, timing may cause trouble and picture will not be stable. When signal is not stable, each function of projection unit will not be guaranteed

for good picture display. Horizontal Timing Vertical Timing
