Why you shouldn’t use someone else’s TV calibration settings

I think you will be thoroughly persuaded by this article.

In short, individual display variance is too significant, and you will probably make things worse. If you want to individually calibrate your TV, don't do it yourself, and certainly not by eye. Have a professional do it.

If you want to learn about TVs and home theater equipment, I recommend following Chris Heinonen and reading his articles. Note that I am only recommending him, specifically.
