Section 3: Operation
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 or
certain digital signals connected to
decoded for accurate color in the display. 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 most digital signals or for signals connected to
entirely automatic and the drop-down list disabled.
The current color space appears in the Image Settings menu. Press
• Select
RGB
• Select
YPBPR
• Select
YPBPR
NOTE: When certain RGB signals are first connected, the projector may not initially recognize them as RGB
and incorrectly decodes 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, 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 Option
Automatic Gain Control (AGC) affects decoded video images only. Enter a check mark (default) in most
instances to activate the decoder's AGC circuit and 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.
