PC Output Signal
The projector has been designed with the RGB signals listed on page En-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
