Display Subsystem
The following is a basic description of the Display Subsystem hardware. Refer to Section 5 -
High Resolution Displays for detailed circuit descriptions, troubleshooting information, and component replacement
instructions.
The Display Subsystem consists of two 16-inch, high resolution, high contrast, high brightness, monochrome monitors.
Each monitor can display up to 1030 lines per frame with 1320 pixels per line maximum. The left-hand monitor is
called the Primary display because it shows newly acquired images. The right-hand monitor is called the Secondary
display; it shows acquired images and provides a mounting place for a Touch Screen assembly that you can use with
a CRT-displayed graphical user interface to control many system functions.
The monitor frame serves as the mounting point for the X-Ray On indicator , infrared remote sensors , ambient light
sensor , and the lighted ON/OFF pushbutton , which are described elsewhere in this section.
