Quick question... I keep researching this for a friend and can't figure it out. He's trying to get a third monitor working, but he can't get more than two monitors enabled at a time. I believe it's the Display Port. The one he got, it doesn't specify whether it's active or passive.. can anyone tell me?

That's the one he had bought. If it's a passive one, I'm assuming that's what the issue is.. since his 6670 should let him run three monitors at once.

It shows a third monitor, but it doesn't let him extend to it. The only way he can extend to it is to disable one of the other ones. So all the monitors work.. it just won't allow more than two at a time.

Was going to have him grab this one from NewEgg:

Sounds very much like a passive adapter your friend has currently. I recall converting from DisplayPort to DVI or HDMI requires some sort of clock chip. With 2 displays, a passive adapter uses one of the clock chips on the video card's DVI/HDMI outputs.

I don't know a great deal about all this stuff, but by Googling and looking up some stuff, along with getting the model number of the adapter he got.. it seemed to me that it was an adapter issue.

I told him to grab that one from Newegg, so we'll see in a few days :)
