Adjusting the clock frequency (PICTURE ADJ) and clock phase (FINE
PICTURE) manually
When "AUTO PICTURE" is set to "ON," the clock frequency and clock phase will be adjusted
automatically. However, if you need any manual adjustment for these two items, you first need
to set "AUTO PICTURE" to "OFF" as indicated in the following steps. Adjust the clock
frequency to eliminate any vertical banding, then clock phase to reduce any video noise, dot
interference, or cross talk. (When clock phase is not matched evidently, the image appears to be
shimmering.)
