By default, the projector can utilize any of four calibrated factory-set color
temperatures: 3200, 5400, 6500 or 9300 (expressed in degrees Kelvin). For most
applications, these temperatures will display accurate and realistic colors from a
variety of sources. They can be selected at any time in either the Image Settings menu
or in the Advanced Color Temperature menu.

However, if you require extra color temperatures, you can also add up to five custom
color temperatures–four "User" and one "Interpolated"–by defining them within the
Advanced Color Temperature menu (each defaults to 6500K until then). Any "User"
or "Interpolated" temperature created here is immediately applied, or it can be
selected at any time from the Image Settings menu as usual, regardless of your source
or channel. The Advanced Color Temperature menu options are described below.
NOTE: For best results, use an internal grayscale test pattern when working with
color temperature.
See Figure 3.20. Upon opening the Advanced Color Temperature

menu, the current temperature appears as the top option. You can change to a
different color temperature here as desired, just as in the Image Settings menu. Note
that if you select a "User" color temperature, the "White Level" options further down
in the Advanced Color Temperature menu are no longer disabled—you can adjust
them as desired to define or change a "User" color temperature (see "White Levels",
below). Likewise, selecting "Interpolated" here activates the "Interpolated" slidebar
for defining or changing an interpolated color temperature.
Select this option if you need a specific color temperature that lies

somewhere between one preset color temperature and another. Adjust the slidebar to
define a new temperature which will be interpolated from the neighboring presets
(for example, 7841 is interpolated from 6500 and 9300). It can be used any time and
appears as a 4-digit temperature when present.
These 3 controls are adjustable only if a "User" choice is selected (in

which case "User 1, 2, 3 or 4" appears at the top of the Advanced Color Temperature
menu). Their current values are shown for the active color temperature. Changing a
white level here changes the drive (contrast) for that color, essentially creating a new
color temperature that is "warmer" or "cooler" etc. For maximum overall
brightness, always keep at least one white level at 100. When you are satisfied with
the new "User" temperature, it can be used immediately upon exit or it can be
