A HP model I'm looking at has a Display port and a VGA port
1) would this natively support output to two screens at the same time?
2) Display port seems to be getting more common but I've not seen a monitor with it? is it easy to connect display port to say a DVI or even HDMI monitor?
3) on q2 above, if existis, are the ables expensive?
4) If does not support two screens, anyone recommend and (ideally officially HP supported under HP warrnaty) graphics card that will give this?
