Nvidia Customer Help Reply
I am in work so not tried this yet - sounds like twaddle to me!
But here it is in all it's glory the Nvidia reply to my query re the fault/ problem. Waited two days for that, but I would have thought that the options should be there automatically (with drivers) as windows detects the cards capabilities without the drivers.
kalniel - again thanks for your help. Black.
