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.

VIDEO STANDARD:
standards available in the world, the projector automatically
detects the incoming horizontal and vertical frequencies and
sets the projector's processing of this signal to the
corresponding standard. The current video standard name
appears in the Video Options submenu, and includes an "A" if
it has been auto-detected. Press
different video standard from those available to the
projector—any that are disabled have frequency
characteristics that differ from those of the incoming signal. Selecting a specific
standard forces the projector to process the signal according to this standard.
NOTE: Best results are obtained with defined channels. Otherwise, switching from
one video source to another can sometimes cause slight disturbances in the display,
indicating that the Auto function is struggling. Recover by briefly selecting a different
video standard, then going back.
