How to Enable the On-Board Video Card and PCIe Video Card Simultaneously on a Gigabyte 78LMT-USB3 Motherboard

I recently built a computer using a Gigabyte 78LMT-USB3 motherboard. The board has an on-board graphic card. I also installed an additional AMD/ATI HD 3400 card to connect the computer to two monitors using HDMI ports. After I’ve done assembling the computer, I found that only one video card is enabled at any given time. If I specify the on-board video card as the primary display, the PCIe AMD/ATI HD3400 is disabled. If I specify the PCIe video card as the primiary display, the on-board video card is disabled.

I contacted Gigabyte support hoping to find a way to enable both the on-board video card and the PCIe AMD/ATI HD3400 card. Surprisingly, I got the answer pretty quickly. The tick is to enable Surround View. Here are the steps:

1. Reboot the machine.
2. Immediately press DEL key to enter BIOS when the machine boots up.
3. Select MB Intelligent Tweaker (M.I.T.) and press Enter.
4. Select IGX Configuration and press Enter.
5. Select Surround View and change it to Enabled.

Note that this option is only available for ATI video cards.
