How to perform a coarse linearity adjustment by using the Side Bows?
We assume
side bow top
is selected.
1. Push the cursor key ↑ or ↓ to select
pixel x = 0
in the
Geometry Distortion
menu. (menu 6-63)
2. Push the cursor key ← or → to coarse shift the selected Side Bow in a horizontal way.
3. Repeat step 1 to 2 for the Coarse
side bow bottom
selection.
This will shift the vertical center line, resulting in a coarse horizontal linearity adjustment (Follow this procedure in a similar way
to shift the horizontal center line). (image 6-23)
4. Use the subpixel adjustments to fine shift the selected Side Bows.
5. Continue with the Coarse Center adjustment or press
EXIT
to return to the
Guided Geometry Map
menu.
