A quick fix you might attempt would be making visible, then clicking, the 'Detect Displays' button in the Displays pane of System Preferences. It can be made visible by holding the Option key once you've brought up the Displays pane (it will appear at the bottom right near the question mark).
If that doesn't get things working, I'd recommend taking a look through the following article, as it provides a whole host of useful troubleshooting steps for just such a situation.

Unfortunately after spending over an hour working on this I still am not having any luck. I will probably go to the nearest Best Buy tomorrow to try to figure out the problem. Thank you for your input.
