Powercooler r9 280x - 3 monitor display, used to work now it dosen't

[Destiffmast]

Hi guys, long time reader but first time user of the forum.

I had my pc running 3 cards for a few months with out any problems, connections I use is 1 hdmi connected to middle screen, and the side monitors connected to via the 2 mini dp ports.

I know it is not a connection problem because it used to work fine with 13.12 driver but since I updated my driver to 14.4 all went bunkers... So I downloaded the AMD driver removal tool and installed the old drive again but the same problem happens, every time I want to extend the third monitor tells me I have to disable one of the connected monitors. CCC and windows see the third monitor but don't let me use it.

I am baffled with this one and can't get my head around it, anyone knows what might be the problem? I am sure it must be a setting configuration missing but what is it is the question...

I think its a driver bug that effects some systems and system restore to when 13.12 were originally installed would be the easiest solution.

Thanks you for your reply.

I have tried that but no system restore available, it seems I have deleted by accident recently. Is there any other way?

When I start the pc side screen come up and middle one is off, then the side screens go off and I log in in the middle one, after logged in I have middle screen and one of the sides working but extending to 3 just does not happen. I have tried several times uninstalling the drivers with AMD tool and also Driver Sweeper then install again 13.12 and latest one 14.4 but same thing always happens... Getting gray hairs here

I have also make a new windows intallation and installed latest AMD drivers, that didn't work either, then I tried another gpu exactly same model, that didn't work either... Could the chipset in the motherboard have anything to do with this problem?

No ideas what could be then?
