Video Options

— SUBMENU
This submenu is used with video
sources only (Inputs 3 or 4).
ENABLE DECODER AGC:
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.
Table 3.3. Regions and Video Standards: Summary
Standard Where Used
NTSC N. America and Japan
NTSC 4.43 A tape-only standard for partially-translated hybrid signals
PAL Most of Europe, China, Australia, some of S. America, some of Africa
PAL-M Brazil
PAL-NC Argentina, Chile, other Latin American countries
PAL 60
SECAM France, Eastern Europe, most of Africa
NOTE: Generally, use "Auto" for all instances EXCEPT: 1) a poor quality input
signal or 2) a black-and-white video signal. In order to detect and display such
signals, select the relevant standard from the list.
INPUT VIDEO BLACK —
compensates for incoming elevated black
levels present in certain video signals, and
ensures that blacks in the display are
neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e.,
where blacks appear dark gray). By default, the projector automatically determines the
best setting according to the type of incoming video signal:
•
0 IRE
– Used for DVD output with "enhanced black", SECAM, most
PAL standards, and Japanese NTSC.
•
7.5 IRE
– Used for most NTSC video signals.
