It is possible that he standard "nv" driver does not support that port on your video card and that you will need to instead download the proprietary drivers from nvidia's website to get that port to function. Regardless of which driver and cable you use, the resolution/freq of the screen is going to be the same ... why not just use the old cable :D Thanks, Johnny Hughes -------------- next part -------------- A non-text attachment was scrubbed...
