ELECTRICAL ADJUSTMENTS
Necessary equipment and connecting
Connect the following equipment as shown in the right fi gure.
• This
projector
• Personal computer
• Monitor for personal computer
• VGA cable
• Signal generator (equivalent to VG-812)
• SVGA_WRGB_64scale signal (for C/W delay adjustment)
• XGA_WRGB_64scale signal (for C/W delay adjustment)
Test signal
• SVGA signal (Vertical frequency 60 Hz)
• XGA signal (Vertical frequency 60 Hz)
• NTSC (480i) signal (Vertical frequency: 59.94 Hz)

29 White / black signal
30 SMPTE (White) *
* Though the signal generator supplies this signal
as a green signal, the projector receives it as
Y/C

Therefore, this signal is projected as a full white
SMPTE signal.
