the system allows for video output in two formats: composite video and s-video. this is accomplished through the proprietary "multi out" connector on the rear of the system, which was carried over from the snes and later reused on the gamecube. although the digital-to-analog converter chip used in early models had the capability to produce rgb video, it was not connected by default for this purpose, and later revisions lacked the pin connections for this purpose entirely.
