Is it your sig rig that is having this problem?
Your sig rig shows GTX470 SLI. If so, then it is Nvidia Surround (vs AMD's Eyefinity).
Anyway, go to the OSD Menu of that problematic monitor and choose Custom Scaling and then Fit to Screen. If you see black border around four edges, this phenomena is mostly likely 'Underscan'. And I bet that monitor is connected via HDMI rather than via DVI.
If this does not work, provide more details (the brand and model number of your monitors, cables and adapters used, how you connect the monitors).
