RGB Lock Sync Adjustment
NOTE: Select Lock Sync after the size and position adjustments.
1
Select a vertical line pattern to display in the RGB window, and select Lock
Sync. The Lock Sync Coarse and Fine buttons appear (refer to the
following illustration).
Coarse and Fine Controls
NOTE: The preferred setup method is auto-calibrate for RGB.
NOTE: The vertical line test pattern should look uniform. If you see dark vertical
bars in the test pattern, adjust 'Coarse' or 'Clock' to eliminate bands. If you see only
horizontal noise, adjust 'Phase' or 'Fine' to reduce or eliminate noise. You may also
need to perform the vertical line adjustment again after changing the size of the
display image.
NOTE: The screen resolution of an older laptop may not allow you to see the
complete adjustment. For example, going from 800 to 1200, you may have to scroll
the screen to view the entire image.
2. Adjust vertical line pattern to look flat and uniform (no color shades, dark
areas, etc.). Refer to the following figure.
