Displaying Zebra Patterns For Adjustment - JVC GY-DV300 Manuel D'instructions

MANUAL ADJUSTMENTS
Zebra patterns are oblique stripes than can be displayed to indicate very bright areas of the screen.
Areas where zebra patterns are indicated are likely to be blurred with white if left unadjusted. The zebra
patterns can be used as a reference for manual adjustment of the brightness to adjust to the optimal
level.
