I just tried dual screen on my GeForce 210. Both using VGA, one goes to NVIDIA's and another straight to the CPU, it failed, and now i've took away the 2nd monitor. Right now my main monitor's display is smaller than my monitor itself, i've tried changing res, restarting, etc. Nothing works. On top of that, the 2nd monitor is still detected in the system even though its unplugged and restarted.
