DisplayPort

As of current, the Intel graphics processing unit (GPU) on the CPU carrier card incorporates up to

three external DisplayPort video channels. At least one video output is available via the CPU card front

panel DisplayPort connector. The PC1-GROOVE is equipped with a single standard DisplayPort front

panel receptacle, while the SC1-ALLEGRO and other CPU cards offer two mDP (Mini DisplayPort)

connectors.

For applications with need for a second or even third independent DisplayPort video output, the

SCS-TRUMPET is equipped with a standard DisplayPort front panel receptacle, in addition to the CPU

card front panel video connector(s). The related SCS-TRUMPET DisplayPort video signals are passed

from the CPU carrier board through an inter-board mezzanine connector to the side card.

Independent operation of multiple displays (e.g. Windows® Expanded Desktop) is enabled by the

Intel graphics drivers (for the Intel download link please refer to the respective CPU card homepage at

www.ekf.com). You can also check your drivers for latest updates by the Intel® Driver Update Utility

www.intel.com/p/en_US/support/detect/?wapkw=(driver+update).

The DP inter-board mezzanine connector on the SCS-TRUMPET mates with the SDVO2 connector on

the PC1-GROOVE, or the SDVO/DP connector on the SC1-ALLEGRO and PC3-ALLEGRO. Consult the

respective CPU user guide manuals in order to achieve the suitable configuration for DisplayPort

operation across this mezzanine connector. The SDVO mode is suitable only for side cards with DVI

video connectors. For the SC2-PRESTO and SC3-LARGO CPU cards this connector is named DP - the

name says it all.
