50 Runco VX-33i Installation/Operation Manual
PRELIMINARY
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.
Brightness: On your external test pattern source, select a PLUGE pattern. (PLUGE is an
acronym for “Picture Line-Up Generation Equipment.”) Figure 4-2 shows a typical PLUGE
pattern.
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).
When you change a picture quality setting, save the change to a
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 54.
