HI every one icon_e_biggrin.gif , i bought a MSI R9 280X Gaming edition 3G, it works fine on OS X Yosemite but only with 2 monitors, i'm wondering if some one succeeded to get it work with 3 monitors, actually i'm using the 2 mini display port and the HDMI and Dvi doesn't working at all.

Thanks for help. icon_thumbup.gif

I have dual Sapphire R9 280x's and couldn't get all the ports to work with ATI injection. I tried various frame buffers, including modifying and patching different frame buffers to try and create one that would give me all the ports. Finally what worked was to simply turn off ATI injection completely (I use Clover). Once I did that, all the ports worked fine. I only have a dual monitor setup, so I have not tried three monitors, but it's a simple thing to try and just might work. I did not notice any performance decreases under multiple benchmarks. The only change I could see was that my cards were displayed at AMD Radeon 7xxx in the system report rather than the correct name which was there with ATI injection.

Hi.

 

How did it go? I've got two displays working on a R9 390 with a third one showing a black picture. I have to Inject ATI since I'm using a patched FrameBuffer and Device ID (390X), so it would be interesting to know it that fixed problem as well B10.
