• Mode: With the VX-44d/-55d, two color temperature adjustment modes are
available: Simple or Advanced. The two modes are mutually exclusive; when you
select the Simple mode (or if Advanced mode is not supported by the projector), the
Advanced selection in the Color Temp menu is grayed out. Likewise, when you
select Advanced, the Simple selection is grayed out.
• Simple: Use Simple mode to choose one of five color temperature presets: 3200K,
5500K, 6500K, 7500K and 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.
