You didnt specify what Operating System you have but lets say you have Windows 7.

Right click the desktop
Go to Screen Resolution
Click on the Monitor in question (If you dont know which monitor it is, click on Identify, if the screen is black/not active, click on Detect)
Change resolution size to your desired size.

The reason being it sometimes defaults to the resolution size of the other monitors. Some of my jobs workstations does this as well when working with different screen sizes.
