Multi monitor support
I'm thinking of purchasing a Dell XPS 16 laptop. I'm thinking a Core i7 820QM and an ATI Mobility RADEON HD 4670 - 1GB. It comes with displayport, HDMI, and VGA output. Am I correct in thinking that with a displayport-2-DVI adapter and an HDMI-2-DVI adapter, I could extend the laptop screen onto 2 DVI monitors and 1 VGA monitor? If the laptop RGBLED supports 1920x1080, would each monitor connected reduce the available resolution? Finally, would a Matrox setup be preferable to these direct connections? As you can see, I know very little about video. Thanks for any info.
