My old computer (it's about 5 years old) had a cable that converted it's video card output to my VGA monitor. I've lost the cable, and can't find a replacement. I'm not sure what type of video card output it is, but someone mentioned that it might be a "Matrox". The output is a D-shaped plug, about 7/8" long, with four rows of 15 holes each (there is one hole missing - so it's actually a 59-pin connection). Unlike the DVI I tried, the input does not have a place for any flat pins. Any idea what this is, or where I can get a converter cable for it?
