I spent nearly 2 hours trying to get it working yesterday (or rather spent 15 minutes trying to get it working, and 1 hour 45 minutes trying to undo the damage and get my computer useable again). I decided to try again this evening and got it working in 5 minutes.

This picture is a (slightly chopped) image of my complete desktop. The original image is 3200×1024, my actual screen resolutions are 1920×1200 and 1280×1024 so the image cropped 176 pixels off the bottom of my big screen.

Mind blowing screen real estate! Awesome!
