B10 Posted June 21, 2015 Share Posted June 21, 2015 HI every one , 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. Link to comment Share on other sites More sharing options...
golfleep Posted June 22, 2015 Share Posted June 22, 2015 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.

hreggi89 Posted December 30, 2015 Share Posted December 30, 2015 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.
