Pls check out my attached System Info.
The problem is, no matter what kind of solutions i used via Google, it just won't work, neither of my Graphic cards is working, the resolution stuck at 1024 x 768 forever. i tried intel HD 3000 graphics drivers, manually change Dev ID within the info.plist and all, totally in vain.
Would sb pls enlighten me here ? Many thanks.
My laptop is Alienware M17x R3, it's under my signature here, u could check it out~
