Calibration - Runco Video Xtreme VX-2000d Operating Manual

Use the Calibration menu to perform advanced picture quality adjustments. This menu
should be used by ISF-certified technicians only.
You must enter a passcode to access the Calibration menu.
Note
To recall the ISF Night or ISF Day settings, do one of the following:
• Select "ISF Night" or "ISF Day" from the ISF Presets menu (see above);
• Press ISF NIGHT or ISF DAY on the remote control; or
• From this menu, choose Display Color, Input Image or Input Color for the preset you
want to recall.
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.
Adjust Gamma before Offset. Gamma provides coarse adjustment of
Tip
low-lights; Offset provides finer adjustment.
• 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.
• Lamp Power: Select Lamp Power from the Display Color menu to adjust the lamp
output level. You can choose to run the lamp as bright as possible ("1") or you can
choose the lower setting ("0"). Generally, lower lamp output can prolong the life of the
lamp, but decreases brightness.
