Calibration Use the Calibration menu to perform advanced picture quality adjustments. This menu
should be used by ISF-certified technicians only.
To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF
Presets menu (see above).
ISF Night - Display Color: Use the Display Color settings to change the characteristics
of the output signal. These settings are global (independent of any particular input).
• Gain: Use the Gain controls to correct color imbalances in the bright areas of the
image. A good way to do this is to use a test pattern consisting mostly of solid white
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red,
green or blue, decrease the Gain for that color.
• Gamma/Offset: Use the Gamma and Offset controls in the White Balance sub-menu
to correct color imbalances in the dark areas of the image.
A good way to do this is to use a test pattern consisting mostly of dark gray areas,
such as a 30 IRE “window” pattern. If the gray areas contain traces of red, green or
blue, decrease the Gamma or Offset for that color.
• Iris: Select Iris from the Display Color Menu to increase or decrease the Reflectance
Volume Regulation setting. RVR lets you control the aperture or iris size (the physical
opening through the lens; similar to an “f-stop” on a camera). Doing so allows you to
optimize brightness and contrast according to the amount of ambient light in the
viewing area.
Use a lower setting (0 or 1) for rooms with lots of ambient light. Use the higher setting
(2) for more “theater-like” viewing conditions (little or no ambient light).
• Color Temp: Select Color Temp from the Display Color menu to adjust the color
temperature. The default setting is appropriate for most situations. Higher settings
produce a “bluer” picture.
