The Auto Key
If the image projected is from the computer, project it on the screen and then
press the AUTO key to automatically adjust the set up of this projector with the
computer signal.
Press the AUTO key when the image is displayed in a WINDOWS-like
screen of a computer. Sometimes a certain computer input signal may not be
able to match the functions set up by the AUTO key, then the OSD Menu
must be utilized for further adjustments.
The Resize key
The RESIZE key enables one to choose the resolution of image input by any
computer video signal.
When the image size of a computer is not over XGA (1024 x 768 pixels) for
its resolution, you may choose either the central-image-projection display
(Windows display) or the whole-image-projection display (Resize Display) for
your image display mode.
If the resolution of the image display is beyond the XGA resolution (1024 x
768 pixels), you may choose to display a certain part of the image projected
(Windows Display) or to display the whole part of the image projected
(Resize Display).
Note: The RESIZE key is not suitable to be used for the adjustment of a XGA
(1024 x 768 pixels) image.
