The menus are grouped by usage:

•The Picture menu provides image adjustments.

•The Settings menu provides set-up type adjustments that are not changed often.

•The Source Info menu provides a read-only display of information about the projector and source.

Certain menu items may not be visible or may be grayed depending upon a particular source being connected. Differences are also seen in analog versus digital video sources and interlaced versus progressive sources.
