Adjusting The Projection Distance - Sharp XV-Z91E Operation Manual

Adjusting the Projection Distance

• Refer to pages 19 and 20 about the function of Keystone correction and placement of projector using the correction.
• Decide the placement of the projector referring to the figures on the table and the diagram below according to the size of
your screen and the input signal.
