Technical white paper - Three-display support with the HP Compaq Elite 8300 Ultra-slim Desktop PC

4
Support for three displays with MXM graphics installed
When the optional discrete MXM graphics solution is installed, the bottom DisplayPort connector and the VGA connector
are controlled by the discrete MXM graphics solution. Any combination of three displays is supported and will work
within the limits of the display interfaces or adapters used. Drivers for both the discrete MXM graphics solution and the
Intel HD graphics must be installed.
With three displays attached, the operating system controls can be used to enable and control some features of each
display. Advanced features can be controlled using either the Intel HD graphics control panel or the control panel
provided by the discrete MXM graphics solution. The Intel control panel will only control the display connected to the top
DisplayPort connector while the discrete MXM graphics solution’s control panel will control the displays connected to the
bottom DisplayPort connector or the VGA output.
NOTE:
The top DisplayPort connector (Figure 1) is always controlled by the Intel HD graphics supplied by the processor. With
MXM graphics installed, the Intel HD graphics can be disabled by using the BIOS menu controls, although doing so will
disable the top DisplayPort connector and limit operation to two displays.
