Input 6
Press
Input 6
to display from the
INPUT 6
interface module installed in the Option 2 slot.
NOTE: If you have the optional Dual SD/HD-SDI Module installed and there are two
inputs connected here, the second input (B) is considered
INPUT 8.
If you are using the
built-in keypad or the remote keypad, press
INPUT 6
to access
INPUT 8
as follows:
•
While displaying from
INPUT 6
, press
Input 5
again. This switches to
INPUT 8
.
•
While displaying from any input other than the Dual SD/HD-SDI Module ,
press
Input 5
, this switches to either
INPUT 5
or
INPUT 8
, depending on which of
the Dual SD/HD-SDI Module inputs (A or B) was last used. Press
Input 5
again
to display from the other Dual SD/HD-SDI Module input.
Contrast
Press
Contrast
to change the amount of white in your images. Use keys until
you reach the desired level of contrast—for best results, start low and increase so that
whites remain bright but are not distorted or tinted and that light areas do not become
white (i.e., “crushed”). Conversely, low contrast causes dim images. See
3.5,
Adjusting the Image (Image Settings subsection) .
Brightness
Press
Bright
to increase or decrease the amount of black in the image. Use
keys until you reach the desired level of contrast—for best results, start high and
decrease so that dark areas do not become black (i.e., “crushed”). Conversely, overly
high brightness changes black to dark gray, causing washed-out images. See
3.5,
Adjusting the Image (Image Settings subsection) .
Gamma
“Gamma” determines how gray shades are displayed between minimum input (black)
and maximum input (white) for a given amount of signal. The proper setting helps
maintain optimized blacks and whites while ensuring a smooth transition for the “in-
between” values utilized in grays. Unlike brightness and contrast controls, the overall
tone of an image can be lightened or darkened without changing the two extremes and
your images will be more vibrant yet with good detail in dark areas when using the
Gamma control.
The normal gamma setting of 2.2 is correct for most signals and conditions. If excess
ambient light washes out the image and it becomes difficult or impossible to see
details in dark areas, lower the gamma setting to compensate. This will improve
contrast ratio while maintaining good details for blacks and whites
