Need help to change resolution

Hello, I installed Leopard 10.5.7 and upgraded to 8 but I was wondering if it is possible to change the aspect ratio of the screen. There is no support for ATI Radeon HD 4670 so I currently have no video driver. Is it possible to change the resolution.


I tried SwitchResX, but I think this needs a video driver since it does not work and I tried using UInstaller

but the aspect ratio does not change. Also my com.apple.boot.plist has been to 1920X1080 but my laptop will not change to that resolution and instead stay at 1400X1080.


If anyone knows how to change the aspect ratio, that would help alot.


My laptop specs:


Dell Studio XPS 1640

Intel 9550 Duo Core 2.66GHz 6MB Cache

4G of ram

Ati Radeon HD 4670 1G

Intel Wireless 5300 (If anyone knows drivers for this, let me know)
