  • Try to connect on of your displays with DP (maybe DP->HDMI adapter) and the other on with HDMI or DVI. I had the same Issue on my R9-270x and solved it that way.

  • Thats probably not going to solve the issue but you can try.
    I have the Sapphire R9 280x Tri-X OC myself. You need to set a framebuffer.
    Do you have a defaults.plist? If yes then please set the framebuffer "Hamachi" and afterwards everything should be fine ;) Please do a NVRam reset after changing the defaults.plist!

    Du kommst bei deinem Problem nach dem unendlichsten Versuch nicht weiter? Dann schreib mir eine Nachricht für eine TeamViewer Sitzung. Nur wenn es gar nicht mehr weiter geht!
