Picture Adjustments
The VideoWall/CineWall 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 Runco video display devices. Accordingly, Runco
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. The source picture is not always optimal in its size or strength; it does not
always conform exactly to a standard. The VideoWall/CineWall provides numerous
controls to compensate for this.
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 hue (tint) adjustments.
(Alternatively, you can use the
Blue Only option in the Input Levels menu.)
Connect your test pattern source to the input that you are calibrating and proceed as
follows. Perform the adjustments in the order listed here.
Copy to Clipboard saves all the current settings to a temporary
memory. You can then make more adjustments to see if it gets
better or worse. Recall from Clipboard restores these saved
settings. The Clipboard is only for testing. These values are not
saved when AC power is off.
While color balancing, change the White value by a lot, not just one
step. It’s difficult to see one step in White. A large change will tell
you if you are heading in the right direction.
If you can’t decide which way to go, try any change. If it is the
wrong change, it will be quickly obvious and you can undo it using
the Clipboard.
