Video is too bright, too dark or washed out
If the video from the source is too light, too dark or washed out, use the offset and gain controls together to
optimize image quality. Increasing the gain amplifies weak signals but also increases noise, you must balance
offset and gain values to achieve the best quality image.
Adjust these settings by the smallest values possible; compensate for a large change to one by making a large
change to the other. Setting both offset and gain to high values can result in poor video quality.
