What way of screen-conection have you been using? Dual-DVI or DVI+VGA cannot not work on any RV710 or RV730 GPU card on OS X. One screen needs to be connected via HDMI. (Tested with 4550 & 4650)

With the two above combinations you can only have the same signal beeing displayed on both screens with using Motmot or Flicker Framebuffer (For example booter like AsereBLN, PC_EFI beta, VGA-PC_EFI 10.6 from my HD46X0 Thread, Chameleon RC4 or ATY_Init with ATY,Motmot in Info.plist). Also this is only working till 10F58 or any earlier Framebuffer kexts + after wake on sleep you'll only have the signal on one screen.



I can take photo of working dual-monitoring also if necessary, but this would require to move my PC and one screen to the living room cause I don't have any HDMI screens around here. ;-)
