Input Signal Settings - Signal Menu

Normally the projector detects and optimizes the input signal settings automatically. If you need to customize the settings, you can use the Signal menu. The available settings depend on the currently selected input source.



Note: You can restore the default settings of the Position, Tracking, and Sync. settings by pressing the Auto button on the remote control.

To change settings for an input source, make sure the source is connected and select that source.
