Pixel densities, and price are major factors here (computer screens being far more expensive per inch than a TV). Computer screens are meant for sitting very close, and TV's are meant for sitting back aways... so the viewing experience will be "off" a bit (due to pixel densities) if you use either for the other purpose. Also, most computer screens don't have COAX inputs, usually only have 1 HDMI input, etc...
