Section 3: Operation
• VIDEO STANDARD
The projector automatically detects the incoming horizontal and vertical frequencies and sets the 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. Press E
from those available to the projector—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.
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.

STANDARD
NTSC 4.43
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 relevant standard from the list.
• INPUT VIDEO BLACK (analog input signals only)
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, selectselect "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.
