• Video Standard—For most available video standards, the projector automatically detects
the incoming horizontal and vertical frequencies and sets the projector's processing of this
signal to the corresponding standard. The current video standard name appears in the
Video Options submenu, and includes an A if it is auto-detected. To view or select a
different video standard from those available to the projector, press Enter; any that are
disabled have frequency characteristics that differ from those of the incoming signal.
Selecting a specific standard forces the projector to process the signal according to this
standard.
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. To detect and display such signals, select the relevant standard from the list.
• Input Video Black—Compensates for incoming elevated black levels present in certain
video signals, and ensures that blacks in the display are neither crushed (where dark
greys appear black) nor excessively elevated (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 is 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 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.
