4-6 Vidikron Vision Model 90 Owner’s Operating Manual
Picture Use the controls in the Picture Menu to calibrate your Vision 90 for optimum picture quality.
The Vision 90 has been designed to incorporate setup and calibration standards established
by the Imaging Science Foundation (ISF). The ISF has developed carefully crafted,
industry-recognized standards for optimal video performance and has implemented a
training program for technicians and installers to use these standards to obtain optimal
picture quality from Vidikron video display devices. Accordingly, Vidikron recommends that
setup and calibration be performed by an ISF certified installation technician.
All signal types require separate processing. Therefore, you need to calibrate each input
separately. Vidikron recommends calibrating the Vision 90 inputs in the following order:
1. Component SD
2. S-Video 1 / S-Video 2
3. Composite
4. HD/RGB 1 / HD/RGB 2
5. DVI 1 / DVI 2
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 -- Sencore VP401 Multimedia Video Generator, Ovation
Multimedia 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.

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 and resolution
separately.) For information about saving settings, refer to ISF Presets
on page 4-10.
