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

automatically determined by the projector, in some circumstances you may wish to
override this and manually set a specific color space.

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.

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.
