First installation 49
horizontal line appears under the bezel. This is the AWS line that is
coming down again.
Note: If you are unable to shift the AKB lines high enough until they
have completely disappeared, repeat the adjustment with a
somewhat higher AKB removal value.
6 Select the AKB removal adjustment. Increase the adjustment until the
line on top of the test image has completely disappeared.
East-West geometry settings
Skewing
Adjust until the vertical lines in the middle of the test image are perfectly
upright.
Trapezoid deformation
Adjust until the vertical lines at the sides of the test image are upright as
well.
Parabola deformation
Adjust until the vertical lines at the sides of the test image are as straight
as possible.
Corner deformation
Adjust until the vertical lines in the corners of the test image are straight.
As a result, the corners of the test image should be 90 degrees exactly.
Bowing deformation
Adjust until the vertical lines in the middle and at the sides of the test
image are straight.
Note: You might have to repeat the east-west settings a couple of times
to obtain a perfect result.
White uniformity settings (on color displays only)
The white uniformity adjustments compensate for the effect of disturbing
magnetic fields on color displays. These magnetic fields cause color purity
or white uniformity errors. The most common is distortion due to the
earth magnetic field.
