Update: When I tried to do a custom resolution in the display settings for the external monitor (not the built in display) it returned a "custom resolution exceeds the maximum bandwidth capacity" error.
I swapped VGA cables and now my computer recognizes the Dell U2412M instead of just Generic PNP. With the computer correctly recognizing the monitor I was able to install the Dell U2412M drivers and it also recognized the correct display settings. 1920X1200. Screen is bright and crisp now, no fuzzy words etc...
I have no idea why one VGA cable allows my laptop (and the HD 4600 Mobile) to recognize the Monitor while the other doesn't, but the Problem is now Resolved!!! Hooray!
