I am running VISTA home premium with a flatscreen TV monitor. The graphics
card is an NVIDIA GeForce 6150 GPU. The monitor resolution is WXGA (1366X768)
at 60Hz. In VISTA control panel, 1366X768 is not available, so I set it to
1360X768 60Hz. With this setting, the desktop fits correctly, but is tinted
purple. DVD images from VISTA Media Center are also purple. If I change the
frequency to 30Hz, the colours are correct, but the desktop is a little too
big for the monitor screen: the task bar is unavailable. What to do?
