after a bit of messing a looking through the forums, i eventually managed to get 1680 x 1050 through my DVI cable ( analogue works ok). however, the problem is that it displays for a maximum of about 1 second before cutting out again - as though the signal is lost completely. Then approximately 2 seconds later, comes back on again. Then repeats.
if i move the mouse it cuts out sooner.
i have found instances on forums of people using this graphics card working at this resolution with DVI.
What would be the probable cause of this and is there any way around it?
