Advanced Color Adjustments
You can select "Image" - "Sharpness" or "Advanced" to adjust the images according to your own
preferences. The adjustment screens for "Gamma" and "RGBCMY" can be displayed on the screen
directly by pressing the corresponding buttons on the remote control.
The adjustment values can be stored in the memory so that you can retrieve them and apply them to the
projected images at any time. (

Hue, saturation, and
brightness adjustment
Gamma adjustment
Adjusting from the gamma
correction values
Use or (UP or DOWN) to select the
correction value that suits the connected equipment
and your own preferences from "2.0", "2.1", "2.2",
"2.3" or "2.4" , and then press or to confirm
the selection.
Observe the gamma graph to check the result of the
adjustment.
When a smaller value is selected, the dark areas of
images become brighter, but the lighter areas may
become oversaturated. This is indicated by bulging
in the upper portion in the gamma graph.
When a larger value is selected, the bright areas of
images become darker. This is indicated by bulging
in the lower portion in the gamma graph.
Hue, saturation, and
brightness adjustment
Gamma adjustment
Differences between equipment may result in a
slight variation in the coloring when images are
projected, and you may want to adjust this.
(Projection will stop temporarily during such
adjustment.) There are two methods of doing so.
One is to select one of the gamma correction values
[2.0], [2.1], [2.2], [2.3], [2.4]. The other is
customized adjustment, which is done with
reference to the projected image or a gamma graph.
The gamma graph's horizontal axis represents the
input signal level and its vertical axis the output
signal level.
Adjustment is not possible when "Color Mode" is
set to "x.v. Color".
The hue, saturation, and brightness for each of the
R (red), G (green), B (blue), C (cyan), M (magenta)
and Y (yellow) color components can be adjusted.
Adjustment is not possible when "Color Mode" is
