I installed Win8 on a laptop, the issue is that the upgrade adviser said the graphics was supported, but when I upgraded, the only modes are 4:3 aspect ratio, which does not match the aspect ratio of the screen.
Toshiba Satellite L350D Laptop, ATI video GPU RS690M. Additional information on the graphics is: ATI video, GPU RS690M, Device ID 1002-791F, AND Driver Autodetect 0x1002 - 0x791F PCI
I have tried device manager => update driver, and searched the net, but finding no driver for this GPU on Win8.
Also tried Microsoftsupport forum, noresponse.
Thanks for any help
