Surround Display Feature
This motherboard supports surround display upgrade. With the internal VGA output
support (DVI-D, D-Sub and HDMI) and external add-on PCI Express VGA card, you
can easily enjoy the benefits of surround display feature.
Please refer to the following steps to set up a surround display environment:
1. Install the ATI
TM
PCI Express VGA cards on PCIE2 slot. Please refer to page 14
for proper expansion card installation procedures for details.
2. Connect DVI-D monitor cable to DVI-D port on the I/O panel, connect D-Sub
monitor cable to D-Sub port on the I/O panel, or connect HDMI monitor cable to
HDMI port on the I/O panel. Then connect other monitor cables to the
corresponding connectors of the add-on PCI Express VGA cards on PCIE2 slot.
3. Boot your system. Press <F2> to enter BIOS 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 BIOS 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.
5. Set up a multi-monitor display.
For Windows ® XP / XP 64-bit OS:
Right click the desktop, choose “Properties”, and select the “Settings” tab
so that you can adjust the parameters of the multi-monitor according to the
steps below.
A. Click the “Identify” button to display a large number on each monitor.
B. Right-click the display icon in the Display Properties dialog that you wish
to be your primary monitor, and then select “Primary”. When 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 identified by the number 2.
D. Click “Extend my Windows desktop onto this monitor”.
E. Right-click the display icon and select “Attached”, if necessary.
F. Set the “Screen Resolution” and “Color Quality” as appropriate for the
second monitor. Click “Apply” or “OK” to apply these new values.
DVI-D and HDMI monitors cannot display at the same time. You can
only choose the combination: DVI-D + D-Sub or HDMI + D-Sub.
