Note 1: MAC adapter is necessary to set the resolution mode.

Projector is compatible with 13 inch mode and 16 inch mode.

Set all dip switches OFF except those indicated in the chart.

For example:

MAC 13" mode = switch 1, 5 and 6 are ON

MAC 16" mode = switch 2, 5 and 6 are ON

(Example of 16 inch mode)

Note 2: XGA (1024 x 768) will have less resolution, due to compression techniques used to display the image

Note 3: Some input sources may not be displayed properly because they are not compatible with the projector.
