I've heard somewhere that BNC cables were higher quality than standard VGA. The logic seemed sound: Individually shielded cables for each signal provide each signal the full bandwidth of the cable. Sort of like component vs. S-Video / composite video cables.
However, now that I have a set I had one of those "Oh yeah" moments when I realized that it's still only one cable, just like a VGA cable and that the head where they split apart is unshielded and therefore is more prone to interferance than a standard 15-pin D-Sub / D-Shell VGA cable. So what truely is the advantage? Also, the guy I got it from had two types, one with the 15-pin connector and one with something much wider. Today, I saw a composite/S-Video/RGB Upscaler VGA box on the 'net which had two VGA outputs. One was VGA and one looked like that wider connector. Is this the standard connector for those BNC VGA cables? Is this the was Sun Solaris or whatever considers standard? Why would the box have both if it's the other end of the cable that makes the difference in what kind of device you can connect it to? So which is truely better, standarg VGA cable or BNC-type?
My monitor accepts both and thankfully has a removeable VGA cable. The cable developed a short so I considered it time for an upgrade. I figured I'd go with BNC because it would be easier to get standard cables in the future when I intend to use both inputs for a compatability system (Dual Voodoo2 SLI Glide + Hollywood Magic+ to one, 2D + Direct3D to the other). I've got BNC and I'm borrowing a VGA cable for now and I can see no perceptable difference so I can't say first-hand what's better
