There's a commercial that I hear on the radio every day endorsing ISF calibration. There's a guy with a cheesy, faux British accent. When I read your posts, I imagine that guy's voice (except he sounds like he's about to have an orgasm when he talks about the improved picture).
Anyway, I went ahead and decided to get a professional calibration done. I'm a television junkie and I want the best possible picture, especially since I paid so much for the TV and the new audio equipment. The friendly advice that I received from someone in the know was no less helpful than the unnecessary snark and condescension. Just so you know.
I'm not a Luddite, yet in spite of my considerable educational background, there's a lot that I don't know about certain subjects and I like to consult the experts, even the smug ones.
