In Topic: Ati Radeon 6870 eyefinity 6xoutput

What type of MDP>DVI convertors are you using?


I'm using XFX Adapter Mini-Displayport to DVI (Active, Single-Link). The active adapters from Club 3D did not work.

and where do you have each monitor plugged in? 1MDP,1DVI,1HDMI?

Yes,1xDVI (upper one),1xHDMI,1xMDP

I have an MSI 6870 and can only get 2 working at a time


Seems like having the right active MDP->DVI adapters is crucial. Like I mentioned above, Club 3D adapters (albeit being "active") did not work, the ones from XFX did.

@baguazao: Nope, if you only need to get 3 outputs to work, I suggest you get a regular 6870; works out of the box for me with 3 monitors.

Any updates so far? I'm struggling as well to get 6 outputs to work with a 6870 Eyefinity 6 (1002:6738).

Using ##### 4.2/Chimera 1.7 and GraphicsEnabler=yes 2 ports are useable, yielding the following sysinfos (AtiPorts=6 does not affect this):

Systemprofiler:

So "Bulrushes" should be the correct framebuffer instead of "Duckweed" for 6 displayports (00 04) on a 6870.

However running any of the following options and their combinations result in a grey screen after the OS X load spinning wheel:
-GraphicsEnabler=No
-PCIRootUID=1
-AtiConfig=Bulrushes
