• Simple: Use Simple mode to choose one of three color temperature presets:
5500K, 6500K or 9300K. The default setting, 6500K, is appropriate for most
situations. Higher settings produce a “bluer” picture; lower ones impart a reddish
hue to the image.
Table 4-2 lists the x- and y-coordinates for each color temperature preset in
“Simple” mode.
• Advanced: For more precise white balance control, use Advanced mode to create
a “custom” color gamut and color temperature. You do this by specifying x/y
coordinate values for each primary color point (red, green and blue) and the white
point.
The default values (shown here) are the RGB color space parameters defined in
ITU-R Recommendation BT.709. You can adjust them up or down by a factor of
0.100; for example, the “Red x” range is from 0.540 to 0.740.
• RVR: Use the RVR control 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 for rooms with a lot of ambient light. Use a higher setting for more
“theater-like” viewing conditions (little or no ambient light).
Input Image: The Input Image controls are functionally similar to those in the Picture
menu (refer to page 66), but are accessible only by entering the Calibration menu
passcode.
Input Color: The Input Color controls are similar to those in the Display Color menu (see
above), but adjust the color balance of the incoming signal. These settings are also saved
independently for each input and display mode.
• Gain/Offset (HD1, HD2 and Component/SCART inputs only): These controls
operate similarly to those in the Display Color menu (described on page 74), but affect
the Y, Pb and Pr signal components rather than the red, green and blue channels.

The Input Image settings establish the “zero point” for the Picture
menu settings, whose values represent offsets from the Input
Image settings. For example, if you set Brightness to 10 in this
menu, setting Brightness to 10 in the Picture menu results in an
actual setting value of 20 (10+10).
