Hi Casey,
The analog cable should still work if you only have one video output from your laptop ports, so thats not the issue.
Have you tried to download the latest video drivers for the laptops video card model and configuring the advanced settings using that.
Or it could be something as simple as a faulty video cable connection, can you try another video cable?
If someone more tech minded doesnt help you first, try registering and posting on

in the PC Hardware - Video section for an answer, you should get an answer there from one of the tech heads.
