Be careful - red/green/blue RCA jacks on US TVs tend to be Y/Pb/Pr component video, not RGB. (In spite of using red/green/blue plugs.) Y/Pb/Pr is *NOT* compatible with RGB, and would require conversion. The VGA port, on the other hand, can usually accept RGB with a simple cable. Usually, but not always - some VGA inputs don't accept NTSC RGB timings, or require the separate sync signal that actual computer VGA provides.
