why ar you mixing the RGB with connectors?
you should have mentioned D-SUB instead of RGB.
now the thng is, both D-SUB and DVI gives same output, only differenec is that:
1: DVI has auto ajdustments of Brighness/Contrast, where in D-SUB you can specifiy your own (manually adjustable).
2: DVI is digital, actually made in case if you are in capturing the video's from TV, then transferring via D-SUB makes their size bigger, and DVI makes their size smaller (in layman's terms).
