Configuring 6 Monitors

On a fresh install of ArchLinux trying to configure my displays. Basically, 3 monitors are running as clones at the moment. The other three are clones of each other too but they are not really accessible or usable. But I can see the wallpaper. Here is a bit more information:

lspci|grep VGA:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii PRO [Radeon R9 290]
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii PRO [Radeon R9 290]

xrandr|grep DFP:

DFP1 disconnected (normal left inverted right x axis y axis)
DFP2 disconnected (normal left inverted right x axis y axis)
DFP3 disconnected (normal left inverted right x axis y axis)
DFP4 disconnected (normal left inverted right x axis y axis)
DFP5 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm
DFP6 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm
DFP7 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm

xorg.conf:

My cards can support up to 8 monitors, but I only have 6 connected. xrandr shows 7 displays... Leaving my confused because it's neither 6 or 8... I don't know how to make them connected so I can configure them. I did manage to get 3 of the monitors working properly together albeit laggy using KDE's display settings... but those settings also displayed these other 3 monitors as disconnected and unconfigurable.

Re: Configuring 6 Monitors

Did you ever resolve this? I'm attempting to put together a similar setup and would like to know if 2 AMD 290's can support 6-8 monitors
