"when you have your ati card installed and are using the catalyst control center, you will no longer be able to adjust hardware acceleration from window--that is what the catalyst control center is for. you want to change screen resolution? use ccc. change screen orientation (portrait vs landscape)--use ccc."
That is exactly my situation. Even called support, they said update the driver
, no help. Can you tell me how to change the setting in catalyst control center please?
