Troubleshooting
PC Output Signal
The projector has been designed with the RGB signals listed on page 39 in mind. Depending on your PC, the RGB signals output
may be different from the design values. In particular, when the internal LCD panel of the notebook PC and external CRT are set
on simultaneous display, the RGB signal output may be outside the compatible range. In this case, it may not be possible to display
the image normally. Set the PC to “external CRT only” display mode.
