Goal is to run 3 x 2 eyefinity at 2560 x 1440.
Currently though I can't get my one display to run at 2560 x 1440. It is the one connected using an HDMI -> Dual Link DVI. Not sure if the problem is the version of HDMI on my gpu or my cable. (only able to get it to run at 1920 x 1080)
So far I have tried setting up eyefinity with 5 displays in 1440p and 1 in 1080p. Got a nice black screen and needed to reboot and fiddle around for a while to get a picture back. Tried 6 screen running at 1080p after that. Greeted by a black screen again. Just manged to get a picture displaying again.
Also tried setting as many displays as I could to duplicate mode. After the fourth one I was no longer able to duplicate any more displays.
3 screen eyefinty works great though. No idea what to try now. I have considered running all 6 displays (@1080p) off mst hubs like you suggested Wermad, but I am currently out of display port cables. Don't think it is worth getting more right now since I am planning to replace my gpu. No idea what ports the next one will have.
edit: I'm sure I read somewhere 5x1 and 3x2 Eyefinity are limited to 1080/1200 per monitor. Or is he just trying to run an extended desktop to all screens?
I really hope you are wrong right now. Going to send AMD an email and see if they can clarify what the limitations of eyefinity are, also maybe give me some tips on how to get this working.
