Input Signal Settings - Signal I/O Menu

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

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