PC Output Signal
The projector has been designed with the RGB signals listed on page 35 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.
