Large white stripe down the center of my screen

Last night a large white stripe (probably about 1.5" appeared on the center of my screen. I've only had this computer for about 2 months, so I had a mini-freak out. I took a screenshot to see if it would show up, but the white stripe isn't in the screenshot so I'm assuming this is some sort of hardware problem. I also tried restarting it multiple times to no avail.

I've heard about the white screen of death... but this is just a stripe.

It's a brand new computer! How can there already be something wrong with it? Should I bring it to the Apple store? I still have the box and everything it came with.
