Crossfire + Eyefinity question

post #1 of 6
Thread Starter 
I have 2 AMD HD6870s and can run them in crossfire. I also have 2 monitors and my hdtv hooked up. Currently, if they are in crossfire, only 2 of the 3 displays work, and to get the other display working I have to turn one display off. Pretty inconvenient if you want to put netflix on the tv and have to go into the screen settings every time.

Well, I know there are things called Active Adapters for that, but the question is do I really need one?
Putting the cards in crossfire seems to turn the outputs of the second card off.
I like to have a monitor playing the game, and another for whatever else I wanna do, usually skype and chat with someone.

This is more of a convenience matter than anything lol, because I usually wont be using all three at once. But I do plan on eventually setting up an eyefinity to game across a few monitors.

Needs an active displayport adapter.

When running triple monitor the third connector has to be off the minidisplayport or displayport. Sapphire has something called Flex technology which allows the third monitor to not require the minidisplayport or displayport connector to be used. read more about it here.

So by using a FLEX card, (which I really wanted to buy, but I found a good deal on a non-FLEX card, so I went with that) you dont need to use the display port. awesome. Does that mean it supplies a third clock frequency so that you do not need an active adapter as well?

IE: will it natively support running 3 monitors without any additional hardware?

Yes. Flex doesn't require anything more than the card to use 3 monitors.
