Laptop Four tabling - Requirements?

[MuppetBingo]

I'm about to buy a new laptop and I'm having trouble finding out what I specifically need to be able to 4-table with no (or at least minimal) overlap.

What size/type screen would be the minimum and what resolution would be needed? what type of videocard?

I will use this computer primarily for poker and getting on the internet. No gaming or anything like that.

If any of you have suggestions on specific laptops that would be great, too.

Thanks
