I have a SIS 661 FX/GX Mirage Graphics(128mb) card in a computer running Windows XP (SP3). The screen flickers to some degree. Changed refresh rates with some but little response. To scroll a web page is jumpy, to move a open window with mouse is jumpy, and finally the aspect ratio is off. The pixels are either wider or shorter than normal giving me a stretched out hoizontal image. There is no software interface for the card and playing with Windows gives me little. Any tips will be appreciated.
