Surround Display Feature
This motherboard supports surround display upgrade. With the internal VGA output 
support (D-Sub and HDMI) and external add-on PCI Express VGA cards, 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 PCI Express VGA cards on PCIE2 and PCIE3 slots. Please refer to 
 page 19 for proper expansion card installation procedures.
2. Connect a D-Sub monitor cable to the D-Sub port on the I/O panel and connect a 
 HDMI monitor cable to the 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 and PCIE3 slots.
3. Boot your system. Press  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 an 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.
