3x30" Eyefinity

post #1 of 15
Thread Starter 
I'm new to Eyefinity so I need help to set up my 3x30".
From my understanding I have to connect all 3 monitors to a single card, even though I'm going HD6970 CrossFire I can't use the 3rd DVI port on the 2nd card is that correct?
If that's the case then I would need an active mini DisplayPort to dual link DVI and besides the Apple adapter, is there other alternative?

1: Don't your dell monitors have a DP port in them? If they do, you don't need more than mini DP to DP adapter.

2: Doesn't the 6970 come with a mini DP to DP adapter, with which you can go mDP -> DP -> (insert any DP to ?? adapter here). I'm not sure about this one.

3: Yes you have to connect all through one card.

Yeh my monitor only has one DVI port so guess I would need an active mini display port to dual link DVI. Any suggestions for such adapter?

sounds like you'll need to get a powered dvi-dp converter.

*shakes head*

Leme get this straight,

Crossfire, 2 cards, but single out. Is there a display port on the main card? If so, you can single that out to multiple display ports for "eyefinity" typically. But if you wanted to use all 3 lcd's, i'd use all ports, as crossfire is typically meant for single out.

I'm going to be doing a 6 lcd setup. 3 across, 2 down. 3x2, what sizes, dunno, but concept is,

I'll have 2x dvi, 1 display, on each card. But i'll also have crossfire setup for the middle bottom card as "display # 1", so that when it goes crossfire, it's the only one on, for most performance.

With what you're doing is basically the mini version of what i'm going to do...

Am I making sense? And if you need dvi to display, or vice versa. Go to monoprice.com for fantastic cable selections and choices.

Maybe, maybe not. That's an adapter for Apple and it's not certed for Eyefinity.

I'd say you have to use the powered Accel from Amazon due to your resolution and it being certed for eyefinity. The unpowered active adapters are only good to 1920x1200, whereas the powered units supports the max resolution of your screens.

In regards to your original post.. For Eyefinity your third monitor must utilize the display port.

Thank for the response guys + rep. According to AMD website then the Accell on Amazon will work just fine:
http://support.amd.com/us/eyefinity/...y-dongles.aspx
I'm just not sure if I get the cheaper one on monoprice as listed above it will work as well, the whole Validated thing make me a bit confused, someone can chime in to verify?
