Setting Up; Adjusting The Projection Size - Epson EMP-TW 700 User Manual

Setting up

Adjusting the projection size

The size of the projected image is basically determined by the distance from the projector's lens
to the screen.
Projection distance
The height from the centre of the lens to the bottom of the screen will vary depending on the lens shift setting.
While referring to the table below, position the projector so that the images are projected onto the
screen at the optimum size.
The values should be used as a guide for setting up the projector.

Lens shift adjustment
The lens shift dials can be used to position the image and is especially useful when using the projector in the
following locations.
Hanging from the ceiling
A screen in a high location
Projector situated to the side so that the screen can be viewed sitting right in front of it
Projector situated on a shelf, etc.
When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens
shift correction is adjusted optically. However, for optimal image quality the lens shift function should not be used.
