Operation
Vidikron Vision Model 90t and Model 100t Owner’s Operating Manual 33
Although it may be possible to obtain satisfactory picture quality using the naked eye and
regular program material, Vidikron 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. 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).
