17" UMBP using external monitor, can't select max resoulation

Hi everyone,

I actually just received my UMBP today and have been taking the time to set it up. I went out and grabbed a DVI connector from the Apple store so I can use my 30" Samsung monitor when I am at home.

My question is when I try to select a resolution for the Samsung monitor it will only allow me to go up to 1280x1024, however the max resolution is 2560x1980 (or whatever it is).

My question is, do I have to install some drivers to make this work or how can I get it to achieve the max resolution?

Also, how do I know when my video card is set to the 9600M GT? I am trying to find that and can't seem to find an option other than when I hit higher graphics performance.

Hopefully one of you can help me out.

Thanks,
James
