Operation
Select Hue from the Video Settings menu and press or to adjust it until the cyan and magenta
color bars (on either side of the green bar) appear to be a single shade of blue.
Backlight
The Backlight control changes the apparent brightness of the displayed image. Its effect is similar to
that of a lamp intensity control on a projector.
Gamma
Select Gamma from the Video Settings menu and choose either 2.2 (default) or Off.
Color Temperature
Select Color Temperature from the Video Settings menu to adjust the color temperature. Color
temperature establishes the “color of gray” by adjusting the 75% white point to various color points.
What are “color points?”
A “color point” is an x/y coordinate pair that defines a color’s location on the standard CIE
chromaticity graph, shown below. (CIE stands for “Commission Internationale de l’Éclairage”
(International Commission on Illumination), the organization responsible for color measurement and
management standards.)
Select a value of from 3200K to 9600K. Higher settings produce a “bluer” picture; lower ones impart
a reddish hue to the image. To select a custom color temperature, select User and set the Gain and
Offset as described below.
i
Like the brightness and contrast controls, the color and tint controls are interactive. A
change to one may require a subtle change to the other in order to achieve the optimum
setting.
