8.0 ADJUSTING THE IMAGE
52 R599790 - FORCE Series User Manual
• Select YPbPr (Video) with a standard definition televised signal (SDTV).
• Select YPbPr (HDTV) with a high definition televised signal (HDTV).
NOTE: When certain RGB signals are first connected, the projector may not recognize them as RGB and will
incorrectly decode their color information as YPbPr (video). These signals can include:
• RGB signals in NTSC, PAL, SECAM frequency ranges.
• Scan-doubled sync-on-green.
• Scan-quadrupled sync-on-green.
For these signals, change the color Space to RGB, and then define a new channel for future use.
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 ENTER 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 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.
l
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.
• 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.
