OPERATION
Roadie 25K User’s Manual
3-31
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
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, then define a new channel for
future use.
Video Options
— SUBMENU
This submenu is used with video
sources only (Inputs 3 or 4).
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.
ENABLE DECODER AGC:
Automatic Gain Control 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.
VIDEO STANDARD:
For all but the more unusual video 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
to view or select a 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.
