Calibration Use the Calibration menu to perform advanced picture quality adjustments on the analog
inputs. 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). Or, use the corresponding buttons on the remote control.
ISF Night - Display Color: Use the Display Color settings to adjust the color balance at the
display device (as opposed to the VHD Controller) for analog sources (up to 1080i). These
settings are saved independently for each 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.
• Offset: Use the 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 Offset for that color.
• Gamma: The default gamma setting (1) is correct for almost all signals and conditions. If
excess ambient light washes out the image and it becomes difficult or impossible to see
details in dark areas, lower the gamma setting to compensate. This will improve contrast
while maintaining good details for blacks. Conversely, if the image is washed out and
unnatural, with excessive detail in black areas, increase the setting. Again, good gamma
improves contrast while maintaining good details for blacks and whites.
• Color Temp.: Select Color Temp from the Display Color menu to adjust the color
temperature. For most situations, the appropriate setting is (1). The higher setting (2)
produces a “bluer” picture; the lower one (0) a “warmer” picture with more pronounced
red and orange hues.
• AGC (Automatic Gain Control): AGC increases the brightness of dark signals
automatically. To enable AGC, set it to 1 (on). To disable it, set it to 0 (off).
• Input Level: The Input Level control allows you to adjust parts which are extremely bright
and hard to see. (This cannot be adjusted when the input signal is digital.)
ISF Night - Input Image: The Input Image controls are similar to those in the Picture menu,
but are accessible only by entering the Calibration menu passcode. This makes it possible to
restore the picture quality settings to what they were when the display was installed, simply
by recalling the “ISF Night” preset.
