Connecting to Various Devices
Before connection, be sure to turn off the projector and connected devices.
Read the manual which comes with each device thoroughly.
Signals that Can Be Input to the Projector
The following signals can be input to the projector:
■ Video signals
(1) Response to color systems
*1:Responds if Y/C output is available.
*2:Signifies that component signals (“Y, P
B, PR” / “Y, B-Y, R-Y” / “G, B, R, H/CS, V”) conform to the signal timing
(synchronization and video period) of each color system. The color systems are used for convenience only.
(2) Response to double density (*3), high-vision signals
*3:Signals whose density of scanning lines/field is twice as high.
*4:Responds to signals whose horizontal scanning frequency is 31.5 kHz. NTSC can be made twice as dense by a line
doubler (separately available: recommended article). Also, possible to respond to fully-specified, decoded
wide-clear-vision signal and decoded 525P progressive signal.
*5:Responds to signals whose horizontal scanning frequency is 33.5 kHz. PAL can be made twice as dense by a line doubler
(separately available: recommended article).
(3) Response to DTV-format signals
DTV-format signals (480i, 480p, 720p, 1080i) can be input to the Y, PB/B-Y, PR/R-Y, G, B, R, H/CS, V input terminal.
■ Computer signals
Signals with the following scanning frequencies can be input to the PC 1 or PC 2 (G, B, R, H/CS, V) and DVI terminals.
Be sure that the computer to be used suffices the following conditions:
•The computer has the video signal output port.
Be sure that the computer has the video signal output port by reading the instruction book of the computer.
The video signal output port is generally called as “RGB port”, “monitor port”, or “video port”. If the computer-monitor hybrid
type or note type is used, it may need to prepare for an external output port. Also, there will be the type to which an external
output port cannot be installed.
• DVI input
During DVI input, depending on the computer settings, there may be no signal input or an error may occur (blue screen).
If this happens, turn off the power to both the projector and the computer, and then turn the projector back on before turning
the computer on again. Then correctly set the computer's graphic board.
•The resolution and the scanning frequencies are within the range specified in the table on page 23.
Be sure that the resolution and the scanning frequencies of the video signal are within the range. A video signal out of range
cannot be used. (Even signals out of the range could be projected. However, it may not sharp enough. On the other hand,
even some of the signals within the range may require adjustment depending on the video board used.)
When a signal other than listed in the table on page 23 is input, the image could be partially erased or an unneeded fold-over
image could appear.
Even signals in the frequency range that can be input may not be displayed normally depending on the type of the signal.
Composite sync (C
S) and G on Sync signals cannot be handled depending on the devices connected.
