Boot up a live distro and see what happens. For me with Mint 17.1 it found both my monitors and automatically configured them. If it works correctly for you then it is a Debian configuration issue, and you can start from there.

I have two screens so I needed to update my display preferences to choose two screens. However this now fails because display preferences insists that the maximum size allowed is 1680x1680 which is smaller than the combined size of my screens. I have no idea why this failure is occurring. Out of desperation I removed my graphics card, rebooted, verified that the default graphics for the computer worked, and then reinstalled the graphics card. But display preferences still insisted that 1580x1680 is the maximum size. I have no idea what to do next other than buy a new graphics card. It would be nice so first establish that the problem is actually hardware and actually the graphics card but I don't know how to do either. I unfortunately do not have a second computer to try out the graphics card on. Anybody with suggestions on what to try next? The graphics card is a Radeon 5430.
