I got the same graphic card... hd 3200 is working fine... but when I installed the Vista drivers (or the drivers that support.asus.com gives for windows 7) it appears hd 3200 and also Hd 4500 Series... all the games and movies work in some kind of window mode.. not full screen.
PS: the card has 2 modes... 4570 works on High performance, and basically when the notebook is plugged in and 3200 on battery and power saving.
PS2: if anybody has a solution for this problem with Windows 7... let us know please.
Hi. Have you found any solution? I have the same problem with acer 7535g only works on hd 3200 on win7! Win vista working on hd4570
