8.5.7.9.4 Vertical Sync Reference

What can be done?
The Vertical Sync Reference can be set in 2 modes:
Direct This sync processing has the disadvantage that glitches and other disturbances in the video signal
sometimes get passed and hence may cause problems in the image.
Indirect This sync processing throws away any disturbances that are not really sync signals. By source switching a
rolling effect on the image can occur. This sync processing is preferred especially with low quality material.

How to toggle Vertical Sync Reference Direct/Indirect?

1. Push the cursor key ↑or ↓to highlight Vertical Sync Reference. (menu 8-33)
2. Press ENTER to toggle Vertical Sync Reference Direct/Indirect.

8.5.7.9.5 Clamp Gating

When is it necessary?

Clamp Gating is useful when protection signals are present in the vertical interval of the video signal (macrovision), that would
otherwise confuse the Limo Pro, causing horizontal brightness differences near the top of the screen.
