incoming signal. Selecting a specific standard forces the projector to process the signal according to this
standard.
NOTE: Best results are obtained with defined channels. Otherwise, switching from one video source to
another can sometimes cause slight disturbances in the display, indicating that the Auto function is
struggling. Recover by briefly selecting a different video standard, then going back.

NOTE: Generally, use "Auto" for all instances except: a poor quality input signal or a
black-and-white video signal. In order to detect and display such signals, select the rele-
vant standard from the list.
• Input Video Black: This control compensates for incoming
elevated black levels present in certain video signals, and
ensures that blacks in the display are neither crushed (i.e.,
where dark greys appear black) nor excessively elevated (i.e.,
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 = 50, choose "0 IRE". If black
appears excessively elevated, use "7.5 IRE".
• Color: This slide bar 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 will be
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. It is recommended 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 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: Enable or disable film motion detection. 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 will move luma (seen as
a shadow where colors overlap) to the right slightly, with colors remaining in place. Decreasing this delay
will move the shadow slightly to the left. If necessary for your current source, adjust so that no shadows
occur with adjacent colors.
