Video Standard
The projector automatically detects the video standard present and displays the name of this
standard here. Press
able to the projector (some will appear disabled, depending on the current incoming signal).
Selecting a specific standard forces the projector to process the signal according to this stan-
dard.
NOTE: This option should remain set at "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,
specify the relevant standard.
Gamma
NOTE: Gamma does not normally require adjustment and is intended for experienced users
only.
The "Gamma" option affects the shape of the gamma curve representing the levels and types of
grays available between minimum input (black) and maximum (white). Generally the best
gamma curve is one that produces maximum contrast, brightness and color performance. See
Figure 3.14.
THE 1.0 SETTING greatly reduces apparent contrast of mid-range signals and represents a
straight transition from black to white.
THE DEFAULT SETTING OF 2.2 is a normal and smooth gamma curve recommended for
virtually all sources, producing good contrast and smooth gray transitions without distorting
colors.
SETTING OF 2.2S OR 2.8S are not true gamma curves but are slightly S-shaped, resulting in
more intense mid-grays. If you use an "S" option, mid-levels in your display will be brighter
(they have more intensity) without whites crushing, however this abnormal grayscale will also
likely disturb color accuracy. Likewise, the 2.2SN curve is also distorted, but can improve some
NTSC signals.
THE 2.8 SETTING offers more apparent contrast of mid-range signals with fewer grays, and
may appear darker than the 2.2 setting. This is the official standard for PAL and SECAM sig-
nals but it is almost never used for real signals which use 2.2.
Select RGB unless you are using component video at INPUT 1 or 2.
Select YPbPr (video) if you are using a standard definition televised signal (SDTV)
Select YPbPr (HDTV) if you are using a high definition decoder (HDTV).
