Just replaced my aging (over 10 years old-!) 27" Mitsubishi with a new Toshiba 32A42. I'm in the process of improving my viewing conditions with the thought of calibrating the set. Was wondering how some of you more experienced folks watch stuff: in total darkness, or with some ambient light? The set seems to be best in total darkness, but then I think maybe a little light would be better. Basically, I want to get my viewing conditions nailed down before I calibrate it. Any opinions/advice will be appreciated!
