Hi All, I've recently acquired a nvs280 card, which is a nv34 gpu based card with a pci-e bridge on the card, this way I can test nv3x problems without needing an agp motherboard. One thing which stands out with this card is that it drivers my dvi lcd monitor at 1680x1050 instead of its native 1920x1080. Is this due to a known limitation on the display pipeline of these cards / nv34 gpu-s.
