Operation
When you change a picture quality setting, save the change to a
Note preset afterwards. Otherwise, the change will be lost when a different input is selected. (Picture quality settings are saved for each input separately.) For information about saving settings, refer to Memory Presets on page 56.
Although it may be possible to obtain satisfactory picture quality using the naked eye and regular program material, Runco recommends using the following calibration tools for best results:
•External test pattern source – Ovation Multimedia, Digital Video Essentials or AVIA test DVD or equivalent.
•A blue filter (provided with many test DVDs), for color level and tint adjustments.
Connect your test pattern source to the input that you are calibrating and proceed as follows. Perform the adjustments in the order listed here.

Figure 4-2. Typical PLUGE Pattern for Adjusting Brightness
PLUGE patterns vary but generally consist of some combination of black, white and gray areas against a black background. The example above includes two vertical bars and four shaded boxes.
Select Brightness from the Picture menu and press ENTER or SELECT. Adjust the brightness so that:
•The darkest black bars disappear into the background.
•The dark gray areas are barely visible.
•The lighter gray areas are clearly visible.
•The white areas are a comfortable level of true white.
•The image contains only black, gray and white (no color).
