One display detected on two monitors and won't detect two

[Daniel-_-]

Hello, I changed a motherboard in my computer and did a reinstall of Windows. When I'm on the computer it shows both monitors working and displaying the same image. I go to Screen Resolution but the "Extend these displays" button isn't there and if I click Identify it show the number "1" on both displays. Any help is appreciated.

Also, both monitors are connected into an ATI graphics card. The one showing up in Screen Resolution is connected with VGA, the other is connected with HDMI and isn't listed.

install the latest drivers from the motherboard manufacturers website. Then go to the graphics cards manufacturers website and download and install those drivers. All should be well then.
