Use the Calibration menu to perform advanced picture quality adjustments. This menu
should be used by ISF-certified technicians only.
Note
To recall the ISF Night or ISF Day settings, select "ISF Night" or "ISF Day" from the
Memory Presets menu (see page 58) or use the corresponding remote control buttons.
Display Color: Use the Display Color settings to adjust the color balance at the DHD
Controller output. These settings are saved independently for each input and display
mode.
• 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 (Pr),
green (Y) or blue (Pr), decrease the Gain for that color.
• Offset: Use the Offset controls 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 (Pr),
green (Y) or blue (Pr), decrease the Offset for that color.
• Gamma: Select Gamma from the Display Color menu to choose a de-gamma curve.
Used correctly, the Gamma control can improve contrast while maintaining good
details for blacks and whites. 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 improves 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.
• Lamp: Select Lamp from the Display Color menu to adjust the projector lamp
brightness.
• Power (230W or 260W): To supply a constant wattage to the lamp, select Power
(230W or 260W) from the Lamp menu to set the lamp power level. You can choose
to run the lamp as bright as possible (260 watts; this is the default setting) or you
can choose a lower setting (230 watts). Generally, lower lamp output prolongs the
life of the lamp, but decreases brightness.
You must enter a passcode to access the Calibration menu.
