Video Options - Submenu
This submenu is used with video sources only.
• ENABLE DECODER (AGC):
AGC affects decoded video images only. Enter a checkmark (default) in most instances. Activate the decoder's
AGC 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 AGC.
• VIDEO STANDARD:
For most 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 is auto-detected.
Press E to view or select a different video standard from those available to the projector—any that are
NTER
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. 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.

STANDARD
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:
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:
• 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.
