Nvidia DisplayPort products don't really work
 

As we don’t have a DisplayPort monitor to prove the claim, we have to rely on our industry sources that have informed us that Nvidia's first DisplayPort cards, mainly the 9600GT, actually don't work with DisplayPort monitors.

There are two Dell models that support DisplayPort, one 24-inch and one 30-inch and our sources said that they have tried a few Nvidia cards and none of them worked with this next generation connector.
