Coarse linearity adjustment using Side Bows
The Linearity adjustment is best done when a reference test pattern is projected on the screen.
By pressing the * key on the RCU an internal hatch pattern is projected instead of the image data.
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 7-63)
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 7-23)
4. Use the subpixel adjustments to fine shift the selected Side Bows.
