Is it possible to send just the video out to a projector without showing the MegaSeg screen?
Yes just open System Preferences, click on Displays, and then turn off the option called Mirroring. This will give you two discrete desktops, the main desktop with the menu bar on your main computer’s screen, and another secondary desktop that can be used for MegaSeg’s video playback. If you do this before starting MegaSeg, it will automatically detect you have two displays and show the videos on the 2nd display. Otherwise you can set MegaSeg’s Video window to Normal Size, and move the video window to the 2nd desktop, and then select the Full Screen video option again. Note you can also turn the Mirroring option on and off from the menu bar if you enable the “Show Displays in Menu Bar” option in the Displays preferences.
