1. Flicker adjustment

● Condition
Video source: VIDEO
Video: RAMP
BRIGHT: MAX
MODE: FULL
● Adjustment procedure
q Display RAMP.
w Rotate VR200: X35-496 until the leading edge of black
area reaches far right of the screen. As shown in the
next picture, the edge is now located at about 1/5 of the
screen width from the left of the screen. (At the comple-
tion of this adjustment, most of the screen will be in
black.)
The position where the adjustment is best completed
can be shown darkest and clearest.
Example: Keep rotating the VR200 so that the black area
is gradually expanded (to the right), and if you rotate the
VR200 too much, the black area will start shrinking. So
when you see the black area starts shrinking, rotate the
VR200 backward a bit to make the adjustment relatively
stable.
