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:
- Reboot the machine.
- Immediately press DEL key to enter BIOS when the machine boots up.
- Select MB Intelligent Tweaker (M.I.T.) and press Enter.
- Select IGX Configuration and press Enter.
- Select Surround View and change it to Enabled.
Note that this option is only available for ATI video cards.
