Need updated driver? AMD Radeon HD 6970M 2GB GDDR5
iMac 27" desktop with Lion OS.
I hooked up a second monitor (24") and want to use it in portrait mode. It works fine in landscape mode.
Is there a way to configure the current video driver or do I need an updated version of the driver for the AMD Radeon HD 6970M 2GB GDDR5 ?
Where is the updated driver if I need it, please?
Thanks.
iMac (27-inch Mid 2011), iOS 6.0.2, video driver AMD Radeon HD 6970M 2G
