Click the Image Setting button from the Configuration screen to access additional settings that affect how the video
image appears.
From this screen you can fine tune the video image.
Image Brightness, Contrast, Saturation and Hue are all adjustable in the same manner. For each video compensation,
you can set from among eleven levels ranged from -5 to +5. The default setting is zero for each adjustment.
You may use the Preview button and the Restore button to fine-tune the image. Press the Save button to store the
image settings, or press the Restore button to recall the original settings. If settings are changed without saving, they
will be affected until the next system start-up.
