Picture Adjustments
The picture adjustments allow you to fine tune the image quality of the selected input.
When you press one of the Picture Adjustments buttons (Color/Tint, Brightness/Contrast,
Size, Center, or Filter) once, the corresponding image adjustment menu for the selected
output (lit Output LED) image appears on the LCD screen. Select the other output using the
Output buttons to call the image adjustment menu for the other output. In either screen,
adjustments can then be made by rotating the Adjust knob or the Adjust knob. Picture
adjustment settings are stored in nonvolatile memory; when the switcher is powered down
and powered up, the settings are restored.
