model or source are disabled and appear dim

• CONTRAST:
"Contrast" increases or decreases the perceived
difference between light and dark areas of your image (0-100). For best results, keep close to 50. For best
results, start with a low value and increase so that whites remain bright but are not distorted or tinted, and that
light areas do not become white. NOTE: If the environment lighting changes, an adjustment of Gamma is
recommended (see below).
• BRIGHTNESS:
Increases or decreases the amount of black in the image (0-100). For best results, keep close to 50. Start with a
high value and decrease so that dark areas do not become black. Conversely, high brightness changes black to
dark gray, causing washed-out images.
• YELLOW NOTCH FILTER (YNF):
YNF is a channel based control with an additional global control. It works on a "last request gets served" basis.
i.e. Enable YNF in the global control, YNF will be enabled. Thereafter; switch to a channel which does not use
YNF, the YNF filter will be removed (or disabled). Then change the global control, the YNF filter will do
whatever is requested; last request is honored.
• COLOR SPACE:
Determines how the color components of an analog input signal are decoded for accurate color in the display.
Useful only for analog signals and certain digital sources. Although color space for these analog signals is
automatically determined by the projector. You may wish to override this and manually set a specific color
space. NOTE: For some signals, the color space function is entirely automatic and the pull-down list is
disabled.
The current color space appears in the Image Settings menu. Press E
• Select RGB unless you are using component video
• 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.
