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:

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
• 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
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.
