System Graphics
The Model 743 and Model 744 Board Computers can be ordered with optional on-board
graphics.
The Model 744 supports up to four optional PMC Visualize-EG graphics cards.
The HP-UX 10.20 ACE operating system supports up to four displays.
The HP-RT operating system supports only one graphics display.
Table 1-4 shows the display resolutions and refresh rates that are supported on current and
older graphics devices.
NOTE: The HCRX graphics options support a Frame Buffer of 1280 by 1024; therefore, the monitor
