Terminology
Saturation
#
Similar to the saturation setting on CRT display units. Saturation multiplies C
B
and C
R
with the same factor. The ratio C
B
/ C
R
is constant. The value of the saturation control is expressed
in %.
Safe area
The safe area is the part of the image that is shown on a display for the defined settings of the area
markers.
Scanning Backlight
The LED backlight illuminates portions of the LCD at a time, thereby decreasing the “hold effect”
and masking the LCD response time. Using the scanning backlight option results in a much better
performance of the LCD screen when motion is displayed.
Status bar
The status bar is displayed at the top of the screen and contains all relevant information related to
the selected inputs for window 1 and window 2. Also the display settings are shown in this status
bar.
Toolbox
The Toolbox is a type of OSD menu that appears on the left side of the screen. The Toolbox is called
by a long press (
) on one of the control buttons or one of the fixed function buttons on the
control panel. Not all of those buttons are related to a Toolbox. The Toolbox allows the user to
change advanced settings.
Under Monitor Display (UMD) bar
The UMD bar is a dedicated space at the bottom of the screen that shows TSL protocol coded
information sent through the RS485 Tally serial connector or through the GPI Tally parallel port. The
UMD bar also shows two Tally lights.
Video gain G
The video gain (expressed in dB) is similar to picture and is only accessible to the user at deeper
levels in the OSD menus. The main difference is that Picture drives the power of the backlights,
while Video gain is a multiplication factor applied on the value of the video signal V
i
in
. Increasing
gain results in clipping of the highlights.
