Hello, i have the same card, what's it going wrong with your card?? If you want to have a good resolution with that Ati mobility you can see a tutorial on Insanelymac, but you can't make functionating the QE/CI for now with this mobility radeon. You have to wait, some people are working to a kext for enable the mobility GPU of the 46xx series
