Well I worked after all, With AtiConfig=Hoolock and AtiPorts=2. Then I get the Displayport working also but only If I dont boot up with it. ( if the monitor is plugged into it when I boot and has power ) it will not work untill I either unplug the DIsplayport cable or Take the power of the monitor. So now I just use my onboard HD 3000 for 1 screen and the other is on the R5770 DVI port and no ghost
Jamdox, So I have a MSI ATI 5770 and tried your Kext ( running Mountain lion ) What I did is copyed it under Sys/Lib/Ext/ and then Chmodded and rebuild the cache. Then I used Chameleon Wiz ot change boot.plist and added Ati - config and Hoolock. I tried connecting Displayport ( nothing ) and nothing on DVI either. However the ATI cards shows up under System report display cards. Chipset Model: ATI Radeon HD 5700/6700 Series Type: GPU Bus: PCIe PCIe Lane Width: x16 Vendor: ATI (0x1002) Device ID: 0x68b8 Revision ID: 0x0000 Am I missing something or is my card different from the one you are useing ?
