Keystone Correction

Remote controller

Auto setup function is provided to automatically execute the setting of Auto setup (includes Auto input,

Auto PC and Auto Keystone functions) in the setting menu by just pressing the AUTO SET button.

Refer to page 47 for the setting of the Auto setup function.

Note:

• Auto Keystone corrects vertical distortion only; it

does not correct horizontal distortion.

• Auto Keystone cannot work when Ceiling feature

is set to

On in the Setting menu (pp.37, 45).

• Perfect correction of the image distortion cannot

be ensured with the Auto setup function. If

the distortion cannot be corrected properly by

pressing the AUTO SET button, adjust manually

by pressing the KEYSTONE button on the remote

controller or selecting Keystone in the Aspect

menu (pp.37, 45).

Fine sync, Total dots, Horizontal position and

Vertical position of some computers cannot

be fully adjusted with the Auto PC Adjustment

function. When the image is not provided properly

with this operation, manual adjustments are

required (pp.32-33).
