how do i make presentation fill screen in PLAY mode?
i am trying to PLAY a keynote presentation in full screen mode but when i press play, it doesn't fill the entire screen. how do i fix this (get rid of the black side bars)?
Set the Keynote slide size to match the display or projector being used:
In Keynote: Inspector > Document > Document: in the Slide Size dropdown menu select custom, then enter the pixel dimensions of the display/projector.
The dimensions for the second display are found in: Apple Menu > System Preferences > Displays > Scaled:
