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.
