Section 3: Operation

3.6.5 Video Options - Submenu

This submenu is used with video sources only.
• Enable Decoder (AGC): AGC affects decoded video images only. Enter a check mark (default) in most
instances. Activate the decoder's AGC circuit to ensure properly bright images. Delete the check mark 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
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.
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.
