Surround Display Feature
This motherboard supports surround display upgrade. With the internal VGA output
support (D-Sub and DVI-D) and external add-on PCI Express VGA cards, you can
easily enjoy the bene
fi
ts of surround display feature.
Please refer to the following steps to set up a surround display environment:
1. Install the PCI Express VGA cards on PCIE1 slot. Please refer to page 13 for
proper expansion card installation procedures for details.
2. Connect D-Sub monitor cable to D-Sub port on the I/O panel, or connect DVI-D
monitor cable to DVI-D port on the I/O panel. Then connect other monitor cables
to the corresponding connectors of the add-on PCI Express VGA cards on PCIE1
slot.
3. Boot your system. Press <F2> or <Del> to enter UEFI setup. Enter “Share
Memory” option to adjust the memory capability to [32MB], [64MB], [128MB],
[256MB] or [512MB] to enable the function of D-sub. Please make sure that
the value you select is less than the total capability of the system memory. If you
do not adjust the UEFI setup, the default value of “Share Memory”, [Auto], will
disable D-Sub function when the add-on VGA card is inserted to this
motherboard.
4. Install the onboard VGA driver and the add-on PCI Express VGA card driver to
your system. If you have installed the drivers already, there is no need to install
them again.
