I have just taken delivery of my Alienware x51, however I have hit a stumbling block straight away. I used to run windows on my MacBook Pro through bootcamp, I had it plugged into my TV, this is the same TV that I have my Dell Alienware plugged into. On my Mac I ran the resolution at 1600x1200 this looked great! However on my Dell I don't have the option to run this resolution and so I'm currently having to run it at 1280x720 as this resolution allows me to give a customized ratio as most of the other resolutions wont fit on screen, however it looks awful! Any ideas how I get it to run at 1600x1200?

Thanks in advance.
