Section 3: Operation
Video Standard Option
Select
Video Staandard
from the
Video Options
menu. With the exception of 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
secondary menu, and includes an "A" if it has been auto-detected.
Press
E
NTER
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.
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 Option
Select
Input Video Black
from the
Video Options
menu. This
control 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.
For some types of video, you can override the setting. The control is disabled for other types of video (and all
graphics sources). Generally, if black appears crushed when brightness = 50, choose "0 IRE". If black appears
excessively elevated, use "7.5 IRE".
Color Option
Select
Color
from the
Video Options
menu. This slidebar adjusts the color saturation level, i.e. the amount of
color in a video image. Lower settings produce less saturated colors - for example a setting of "0" produces a
black and white image. If the color level is too high, colors will be overpowering and unrealistic.
Tint Option
Select
Tint
from the
Video Options
menu. This slidebar adjusts the red/green color hue for true color
reproduction of video and HDTV signals connected to
Input 3
or
4
. For best results, adjust the tint while
displaying an external test pattern-otherwise, it is recommended that tint remain at its default setting.
