Back in the seventies and eighties, an important design choice for a desktop computer was whether to use a television or a dedicated monitor for display. A monitor could give better resolution; on the other hand, some people already had a television and could save money by reusing it.
Suppose the latter argument doesn't apply, and you assume customers will have to buy one or the other. Is there a big difference in manufacturing cost between a color monitor and a TV? Does the monitor save significantly by being free to implement an optimal design instead of complying with NTSC? Does the TV save significantly by being free to have poor resolution?
