2.7 Dual Monitor and Surround Display Features
Dual Monitor Feature
This motherboard supports dual monitor feature. With the internal VGA output sup-
port (DVI-D, D-Sub, HDMI and DisplayPort), you can easily enjoy the bene
fi
ts of
dual monitor feature without installing any add-on VGA card to this motherboard.
This motherboard also provides independent display controllers for DVI-D, D-Sub,
HDMI and DisplayPort to support dual VGA output so that DVI-D, D-sub, HDMI and
DisplayPort can drive same or different display contents.
To enable dual monitor feature, please follow the below steps:
1. Connect DVI-D monitor cable to VGA/DVI-D port on the I/O panel, connect D-Sub
monitor cable to VGA/D-Sub port on the I/O panel, connect HDMI monitor cable
to HDMI port on the I/O panel, or connect DisplayPort monitor cable to
DisplayPort on the I/O panel.
D-Sub, DVI-D, HDMI and DisplayPort monitors cannot be enabled at the
same time. You can only choose two of them.
HDMI port
VGA/D-Sub port
VGA/DVI-D port
DisplayPort

Surround Display Feature
This motherboard supports surround display upgrade. With the internal VGA output
support (DVI-D, D-Sub, HDMI and DisplayPort) 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 PCIE2, PCIE4 and PCIE5 slots. Please
refer to page 18 for proper expansion card installation procedures for details.
2. Connect DVI-D monitor cable to VGA/DVI-D port on the I/O panel, connect D-Sub
monitor cable to VGA/D-Sub port on the I/O panel, connect HDMI monitor cable
to HDMI port on the I/O panel, or connect DisplayPort monitor cable to
DisplayPort on the I/O panel. Then connect other monitor cables to the
corresponding connectors of the add-on PCI Express VGA cards on PCIE2,
PCIE4 and PCIE5 slots.
3. Boot your system. Press <F2> or <Del> to enter UEFI setup. Enter “Onboard
VGA Share Memory” option to adjust the memory capability to [32MB], [64MB],
[128MB], [256MB] or [512MB] to enable the function of VGA/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 “Onboard VGA
Share Memory”, [Auto], will disable VGA/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.
5. Set up a multi-monitor display.
For Windows

you use multiple monitors with your card, one monitor will always be
Primary, and all additional monitors will be designated as Secondary.
C. Select the display icon identi
fi
ed by the number 2.
D. Click “Extend my Windows desktop onto this monitor”.
E. Right-click the display icon and select “Attached”, if necessary.

HDCP Function
HDCP function is supported on this motherboard. To use HDCP
function with this motherboard, you need to adopt the monitor
that supports HDCP function as well. Therefore, you can enjoy
the superior display quality with high-de
fi
nition HDCP
encryption contents. Please refer to below instruction for more
details about HDCP function.
What
is
HDCP?
HDCP stands for High-Bandwidth Digital Content Protection,
a
speci
fi
cation developed by Intel
®
for protecting digital
entertainment content that uses the DVI interface. HDCP is a
copy protection scheme to eliminate the possibility of
intercepting digital data midstream between the video source,
or transmitter - such as a computer, DVD player or set-top box -
and the digital display, or receiver - such as a monitor, television
or projector. In other words, HDCP speci
fi
cation is designed to
protect the integrity of content as it is being transmitted.
Products compatible with the HDCP scheme such as DVD
players, satellite and cable HDTV set-top-boxes, as well as few
entertainment PCs requires a secure connection to a compliant
display. Due to the increase in manufacturers employing HDCP
in their equipment, it is highly recommended that the HDTV or
LCD monitor you purchase is compatible.

please do not clear the CMOS right after you update the BIOS. If you need
to clear the CMOS when you just
fi
nish updating the BIOS, you must boot
up the system
