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
connected to
INPUT 1, INPUT 2, or INPUT 5.
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 digital signals or for signals connected to

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 appear magenta and can include:

•
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
