Hi. I have been given an old computer by a friend, he want's me to reinstall windows on it for him. It has Geforce 6800gs with VGA and a DVI-out ports. My monitor has D-Sub and DVI-D ports. Is there any way I can get it to work on my monitor? I'm hoping that there is a cable I can buy? Is this a analog to digital issue? If so, it is going to be expensive to get an adaptor but I don't mind because I'm sure it will come in handy in the future.
