Trouble cloning display to external widescreen monitor

I got a widescreen monitor today, and I'm mirroring the display, however it only gives 4:3 resolutions. My T410 is 16:10, while my external monitor is 16:9. Attempting to individually output results in a blank screen. Any ideas? I searched a bit on google and didn't turn up much.

Nevermind, found a way to disable the laptop monitor and now I get the correct resolution for the external. It wasn't a hard solution, just had to look a little harder.
