There were two choices with the original. One was the monochrome
graphics card, with its own matching monitor. The other was the CGA,
which ran at NTSC scan frequencies, and output either RGB or
composite video. Much lower resolution than the MGA, but color.
You could connect it to a TV set video input, and I did that once.
(For one, I used it to do the convergence adjustment on my TV.)
Higher resolution color came later, with the EGA, PGA, and later VGA.
