Many older cards like some GeForce 2s, most GeForce 3s & 4s, many of the Radeon 7000s, the Matrox Parhelia and the Voodoo 5 5500 MAC PCI (which can be flashed to work on a PC) had a DVI connector along with a VGA connector. But what was being sent to that DVI connector? In 1999-2000, the analog VGA connector using 0.7v PtP was still the standard, but DVI uses TMDS for a pure 24-bit digital signal. On many boards that have the holes for a DVI connector, there are pads for a chip.
So on the early cards, are these DVI ports being sent true digital signals? Or are they being converted from an analog signal by a special chip? Can these DVI ports display VGA-DOS style resolutions like 320x200?
