Battlefield 4 and other fullscreen games on a dual-monitor setup

[Ademptis]

I recently set-up dual monitors but cannot seem games running on both screens (stretched). This includes games like Battlefield 4. I can toggle between which screen it is displayed on, but not on both? Is this unique to each game or do I need to change some Video Card settings?

Video Card: AMD Radeion HD 7950
Monitor 1: Asus VK248H
Monitor 2: Asus VE247
OS: Windows 7 64bit

I intend to switch out the 248 for a second 247 soon (christmas).

Thanks in advance for any replies.

You need 3 monitors for that, else the crosshair would be in the middle of the screen. You will have a hard time hitting something with 2 monitors and your gaming experience won't be as good as with one or three monitors.

Thanks a lot for replying so quickly. I can't believe that I didn't think of that.
