Adjusting The Main Image; Configuring The Video Sources - Christie M Series User Manual

A message is displayed indicating that the projector is Processing request and the settings are
applied to the displayed image.
8. To disable Keystone, Brightness Uniformity, Edge Blending, and Black Level Blending, press
Func+Help.
This is helpful when, in some extreme keystone configurations, some image corruption may
appear and/or the menus may not be readable. Although Func+Help disables these features,
it does not overwrite their settings. If keystone is simply enabled again, the same image
corruption may occur.
9. After pressing Func+Help, Christie recommends immediately pressing Reset Keystone
Settings, which sets all keystone co-ordinates to zero.

Adjusting the main image

Alter the main image without affecting its size or position.
1. Select Image Settings and adjust the following:
• Contrast—Contrast increases or decreases the perceived difference between light and
dark areas of your image (0-100). For best results, keep close to 50. Start with a lower
value and increase so that whites remain bright but are not distorted or tinted, and that
light areas do not become white. If the environment lighting changes, an adjustment of
Gamma is recommended.
• Brightness—Increases or decreases the amount of black in the image (0-100). For best
results, keep close to 50. Start with a high value and decrease so that dark areas do not
become black. Conversely, high brightness changes black to dark grey, causing washed-
out images.
• Yellow Notch Filter—Yellow Notch Filer (YNF) is a channel based control with an
additional global control, which honors the last request. After enabling YNF, switching to a
channel that does not use YNF and the YNF filter is removed or disabled. Changes to the
global control affect the YNF filter.
• Color Space—Determines how the color components of an analog input signal are
decoded for accurate color in the display. Useful only for analog signals and certain digital
sources. Although color space for these analog signals is automatically determined by the
projector. You may wish to override this and manually set a color space. For some signals,
the color space function is entirely automatic and the list is disabled.
Changes made are applied immediately.
2. To save the changes, press Exit or Menu.

Configuring the video sources

Learn how to configure video sources.
1. Select Image Settings.
2. Select Video Options and configure the following:
• Enable Decoder (AGC)—AGC affects decoded video images only. Enter a check mark
(default) in most instances. Activate the decoder's AGC circuit to ensure properly bright
images. Delete the check mark if a decoded video image exhibits strange color artifacts
such as stripes in highly saturated colors, indicating an incompatibility between this source
and the AGC.
