The DG5 (display generator) board formats images so that they can be displayed on a
monitor or delivered to other devices. The DG5 board has the following characteristics:
• Converts digital data to analog
• Handles all pixel clocking, genlocking, and cursor display functions
• Performs the role of functional manager
• Connects to the graphics display
The default monitor resolution supported by the InfiniteReality2 and
InfniteReality3 board sets and the SuperWide monitor is 1920 x 1200 at 66 MHz. The
maximum output bandwidth is approximately 300 Mpix/s. For two monitors, the
transfer rate is approximately 188 Mpix/s. If you connect more than two monitors,
you must use a combination of low- and high-resolution monitors that are within
the limit of 300 Mpix/s.
Each pipe contains one DG5 board (see Figure 13-8).
