Noise Reduction
“Noise Reduction” is similar to the “Filter” control, but operates in the post-sampling
digital domain with a more subtle effect. Higher settings are most useful for clearing
up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind
that reducing noise (which reduces high frequencies) may also soften the image.
Color Space
“Color Space” determines how the color components of an
analog input signal are decoded for accurate color in the display.
Selecting a color space option is useful only for analog signals
and certain digital sources connected to
INPUT 1, INPUT 2, INPUT
5
or INPUT 6. Although color space for these analog signals is
automatically determined by the projector, in some circumstances you may wish to
override this and manually set a specific color space.
NOTE: For many digital signals or for signals connected to
INPUT 3 or INPUT 4, the
color space function is entirely automatic and the pull-down list disabled.
The current color space appears in the Image Settings menu. Press
to select a
different option:
 Select
RGB unless you are using component video at INPUT 1, 2, 5 or 6.
 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 initially
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 (
INPUTS 3 or 4).
ENABLE DECODER AGC:
Automatic Gain Control (AGC) affects decoded video
images only. Enter a checkmark (default) in most instances—this activates 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.
