CONNECTED DISPLAYS AND FULLSCREEN MODE INTERACTIONS

Overview

Without special hardware or software, a typical computer can only output video resolutions and frequencies that are
supported by the connected display equipment. Display devices communicate their possible input formats via EDID
(Extended Display Identification Data). The EDID data provides information on preferred formats and available alternate
formats.
When connecting the video outputs of the Mbox server to a display device, confirm that the display device appears in
the computer's System Preferences > Displays pref pane. On most Macs, the computer will automatically read the EDID
of displays when they are first connected. It is possible to force the computer to reread EDID from connected displays
by pressing the "Detect Devices" button on the Displays pref pane.
Note: In newer versions of the Mac OS, the Detect Displays button is not visible unless the [option] key is pressed.
Once EDID has been read from the display, the Displays pref pane will display the available formats. By default, the
pref pane will select the preferred format for the display. Clicking on the "Scaled" radio button will allow the selection
of additional formats. Some formats will allow a selection of alternate refresh frequencies, but this will depend on the
display device.
Note: Even after clicking on the "Scaled" radio button, all of the possible formats for the display may not be shown.
Holding down the [option] key and clicking on the radio button may reveal more possible formats.
