BRIGHTNESS
Increases or decreases the amount of black in the image (0-100). For best results, keep close to 50. Start with a

• ENABLE DECODER (AGC)
AGC affects decoded video images only. Enter a checkmark (default) in most instances. Activate the decoder

color artifacts such as stripes in highly saturated colors, indicating an incompatibility between this source and
the AGC.
