Adjusting the Focus

This section describes how to adjust the video focus.

Turn the focus ring on the projector to adjust

the focus.

Tip:

• Focus cannot be achieved if the lens is dirty or

covered with condensation. Wipe off any dirt

or condensation (See page 64).

• If adjustment does not succeed, make sure the

setup distance is between 39.37inches (1.0m)

and 515.75inches (13.1m).

Keystone Correction (Using Projector Button)

When the foot adjust levers are used to change the projection angle, the

keystone correction function can be used to correct trapezoidal distortion

upward or downward by roughly 15°.

Press the Keystone button on the projector

to minimize the trapezoidal distortion.

Tip:

• A keystone correction reduces screen size.

• The keystone correction is stored in memory.

You will need to readjust the image if the

projector is moved to a different location or the

projection angle is changed.

• If a keystone correction makes the image

noticeably uneven, reduce the video sharpness

with the menu commands Video > Sharpness

(See page 44).
