Notes

(Signal sent from the computer)

•If you project an image from a computer with an LCD screen while monitoring the image on the computer, the image may not be projected properly, depending on the computer model. In this case, turn off the computer display. For details on controlling the computer display, etc., refer to the computer’s manual and description on the software for the computer used.

•The projector projects an image by XGA signal (1024 x 768) in full screen.

•The image quality from a computer signal other than XGA may be inferior. It is recommended to set the external monitor connected to the computer to XGA mode (1024 x 768).

•The projector can be also applied to DDC2B (Display Data Channel 2B). If your computer is applied to the DDC, start up your computer after turning on the projector.
