An additional value to an NTSC monitor is it's color range and levels will be a lot closer to what the TV viewer will see than your PC monitor. There are fundamental differences in gamma and chroma range levels between the two. The worst problem is with red and yellow saturation. Something that looks fine on your PC monitor may be totally saturated on a TV screen.
Basically, if your video looks good on the NTSC monitor, it'll look good on a TV set.
