There is no way to calibrate a computer monitor to show you the true color space of an HDTV or other TV. They are different monitors with different means in mind.
If you get a Video IO device like Matrox MXO2 Mini or Decklink option, that connects via Thunderbolt or Express34 (if your computer offers those options) then you can use those to get a video signal to an HDTV...and use that. But computer monitors aren't designed to show you video color. Unless your project is destined for web only release.
