Input Video Black—
Compensates for incoming elevated black levels present in certain video
signals, and ensures that blacks in the display are neither crushed such as, where dark greys
appear black) nor excessively elevated (such as, where blacks appear dark grey). By default,
the projector automatically determines the best setting according to the type of incoming video
signal:
•
0 IRE—
Used for DVD output with enhanced black, SECAM, most PAL standards, and
Japanese NTSC.
•
7.5 IRE—
Used for most NTSC video signals.
For some types of video, you can override the setting. The control is disabled for other types of
video (and all graphics sources). Generally, if black appears crushed when brightness is 50,
choose
0 IRE
. If black appears excessively elevated, use
7.5 IRE
.
•
Color—
Adjusts the color saturation level. Lower settings produce less saturated colors, for
example a setting of 0 produces a black and white image. If the color level is too high, colors
are overpowering and unrealistic.
•
Tint—
Adjusts the red/green color hue for true color reproduction of video and HDTV signals.
For best results, adjust tint while displaying an external test pattern. Christie recommends that
tint remain at its default setting.
•
Filter—
The proper filter setting is automatically set for virtually all signals, and rarely needs to
be changed. Override the only if standard pixel tracking and phase adjustments do not
adequately clear up a noisy video signal, or if a graphics signal appears overly soft. Both
instances indicate that Filter may be set to the wrong option.
•
Sampling Mode—
Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB
or YCbCr 4:2:2. The proper sampling mode is determined automatically by the projector; you
can override this setting.
•
Film Mode Detect—
Enables or disables film motion detection. This is only available for
interlaced or segmented frame sources.
•
Chroma/luma Delay—
Affects any incoming composite or S-video signal, delaying the luma
signal (intensity) in relation to the chroma (color). In the image, increasing the luma delay
moves luma (seen as a shadow where colors overlap) to the right slightly, with colors remaining
in place. Decreasing this delay moves the shadow slightly to the left. If necessary for your
current source, adjust so that no shadows occur with adjacent colors.
•
Split Screen—
Allows a snapshot of the main image to be presented on the right side or lower
part of the screen for evaluation of advanced image processing features. All resizing controls
are honored on both images. However, image processing controls such as, Detail, Sharpness,
Noise Reduction and Adaptive Contrast only happen on the left side or top image. Changing
inputs, channels, or test patterns disables this control.
PAL 60
Note:
Generally, use Auto for all instances except a poor quality input signal or a black-and-white video
signal. To detect and display such signals, select the relevant standard from the list.
