This method worked for me with no ATI Displays installed. I had a hell of a time getting anything over DVI or VGA before installing jccools driver. I think it wasn't recognizing my LCD properly.
1. Install jccools, reboot into non CI/QE mode over DVI, change resolution.
2. Overwrite all extensions with Bronya's extensions except for ATINDRV.kext, reboot.
3. It just works, even DVI!
This is with an 7280 id Ati Radeon 1950 Pro 256mb on PCI-E, running a fresh install of Tub's 4.10 Test1.
Bronya you are a star for getting this working. I've held back on running OSX on my system because of the poor video performance playing videos and such at 1680x1050. I can finally start using OSX every day.
I tried as you have made it - double display works for me through DVI, but does not work qe/ci, works only rotation!
I tried all of the driver:
1) Inside atindrv.kext 4 drivers lay - ATY_Alopias , Aty_Caretta, etc.
2) ATY_Alopias.kext is works DVI, but does not work QE/CI!
3) ATY_Caretta.kext - does not work both VGA and DVI - there is no signal!
4) ATY_Sphyrna.kext - too does not work!
5) ATY_Wormy.kext - works QE/CI and shows through VGA! Through DVI does not show, there is no signal!!!
So it is necessary to code, that worked through DVI !
Me interests that works for others through DVI.
What it " Tub's 4.10 Test1 "? Thanks!
