What kind of output does the cable box have for the HDTV? If you display HDTV on a computer monitor do you think it would be the same quality as a dedicated HDTV monitor?

IIRC, the TW Cable box supports composite out in 480i/p and 1080i and DVI (which is autonegotiated). Audio is AC3 optical or RCA stereo. I'm using the DVI connector for my CRT TV.
