Yes. Both must be Dual Link (for 2560x1440). One must be active. The other one might be passive but I am not sure if you can get away with it. Even so, I do not see any DP/mini DP to Dual Link Passive DVI dongle listed by AMD in their Validated List. So, I would not take the chance unless a few people have actually tried and can confirm that it works. Otherwise, better to play safe to use two Active dongles.

As I see you are in Canada, here is the better price (in Canadian Dollar) for you:- (CAD $93)

Are you sure I need two?? I can always run the second screen in another DVI-Dual Link port? And the Third will use the Active dongle thing.

You'll definitely need two - only one of the DVI ports are dual link.

Ok, I understand this part.

Then after I'll have to buy some DP adapters to mini DP ? with the dungle?

Man, I bet those dungles cost around 2 $ to produce.

EDIT: Is there a way to use the DVI Dual Link of each card instead of the dungle?

i don't know if this helps, but XFX makes active DisplayPort adapters to DVI. they are kind of pricey, when i bought them ($30/ea), but worth it since i don't have to use USB ports to power them. i am using 3 XFX ones (dvi) and one hp one for VGA (blue)

338


Proof they work: Just finished my setup this morning before work

337


at least one of the monitors has to be linked using a displayport connection.

See the diagram below for an illustration:-

Simply put:-
HD6970 DL-DVI output ---> DL-DVI to DL-DVI cable ---> DL-DVI input of monitor #1
HD6970 mini DP output ---> mini DP to DL-DVI active dongle --> DL-DVI to DL-DVI cable ---> DL-DVI input of monitor #2
HD6970 mini DP output ---> mini DP to DL-DVI active dongle --> DL-DVI to DL-DVI cable ---> DL-DVI input of monitor #3
As the 27'' Catleap has 2560x1440 native resolution, the active dongle must be Dual Link as well. From AMD's Validated dongle lists, Accell B087B-003J sells at US$110.

I nominate windfire for Quickest MSPaint Drawer West of the Prime Meridian.

Those adapters are no good for his needs. The ones you linked only support up to 1920x1080. He needs adapters for all the way up to 2560x1600, which cost around $100.

Anyway, should I get 3 x 27" Catleap 1440p monitors or just go with 3 x 24" 1080p?

I don't even know if my Triple 6970 will handle those 3 catleap monitors

What resolution are you running those monitors at?
