Video Options — SUBMENU
This submenu is used with video sources
only (INPUTS 3 or 4).
AUTO COLOR LEVEL: Auto Color Level
affects decoded video images only. Enter
a checkmark (default) in most instances —
this activates the Auto Color Level circuit to
ensure properly bright images. Delete the
checkmark if a decoded video image exhibits strange color artifacts such as stripes in highly
saturated colors, indicating an incompatibility between this source and the Auto Color Level.
VIDEO STANDARD: For all but the more unusual video standards available
in the world, 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 has been auto-detected. Press
to view or select a different video standard from those available to the projector—
any that are disabled have frequency characteristics that differ from those of the
incomingsignal.Selectingaspecicstandardforcestheprojectortoprocessthe
signal according to this standard.
NOTE: Best results are obtained with dened 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 briey selecting a different video standard, then going back.

NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input signal or 2) a
black-and-white video signal. In order to detect and display such signals, select the relevant
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 grays appear black) nor excessively elevated (i.e.,
where blacks appear dark gray). By default, the projector automatically determines the best
setting according to the type of incoming video signal:
• ENHANCED 0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL
standards, and Japanese NTSC.
Video 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 “Enhanced 0 IRE”. If black appears excessively elevated, use “Video 7.5 IRE”.
