HD 5970 - Extend to triple screens Tags: Radeon HD Cable Graphics Last response: April 3, 2012 7:49 PM in Graphics & Displays Share kimstips April 3, 2012 10:34:19 AM Hello, I just bought an adapter to my HD 5970 so I can use 3 screens. But it won't work. I can only use two screens? But I can disable one of the screens to make the other one work, so there isn't any problems with the cables. I took a picture is it will help: http://i.imgur.com/VWaaU.jpg More about : 5970 extend triple screens americanbrian April 3, 2012 10:42:16 AM You have to use 2 Displayport monitors. If you use both DVI-s you are limited to 2. At least that is how I understand it, I assume that there is another displayport hidden in the photo. a little black duck April 3, 2012 10:47:36 AM Is your display port adapter active or passive? To enable eyefinity, the 3rd screen must be connected via an active display port adapter. http://support.amd.com/us/eyefinity/Pages/eyefinity-don...

Does this also apply when I just want to extend it? americanbrian April 3, 2012 12:46:39 PM It is something to do with some synchronous clocks somewhere. Displayport can duplicate them, DVI can't or something. Anyway, ALBD seems to have it right, check out the link he posted. Yes, I believe it is an absolute requirement for 3 displays. kimstips April 3, 2012 6:56:08 PM Okay, thanks for the help! kitsunestarwind April 3, 2012 7:49:36 PM Yes adapter has to be Active, if not no 3 screen. Once you have that active adapter it will run 3 screen fine (used to run triple display on my pair of 5970's) Can't find your answer ? Ask !
