Centering Adjustments

These adjustments permit you to properly center the picture to the screen. They will not impact geometry or
convergence settings, but they will assure that the picture is properly positioned within the screen.

To center the picture, press “

MENU

” to display the Main Menu, and then press “

4

” to access the Centering

screen.

When the Centering screen is displayed, use the 

/ / /

 directional arrow buttons on the remote until the

picture is properly centered both vertically and horizontally on the screen. If there is any overscan it should
be equal to the top/bottom and left/right edges of the screen.

Blanking Adjustments

Blanking adjusts the video timing signals that determine the outer edge boundaries of the picture at the
top/bottom and left and right. This is different from the centering adjustments in that the picture, itself, is not
moved on the face of the CRT or the screen. Blanking adjustments may be likened to moving “blinders”
across the underlying picture to mask portions of it off.
To adjust blanking, press “

5

” to access the main  Blanking

screen.

the picture to the desired place on the screen. When finished, press “
