If any part
of the screen does not display correctly in the projection, the aspect ratio
may have been accidentally changed.
To change the
image ratio and thus have a full screen, press the Aspect button using the
projector remote control and choose Auto mode.
The camera will need to be calibrated if you have changed the projection ratio.
