(sticky?) TN vs PVA vs IPS, and yes, you can use a TV as a monitor.

You should know response times truly don't matter. It's really the Hz. A 120Hz offers smoother game play and picture over a 60Hz. It really takes a monitor more than 8ms to go from white to black.

Response time matters man. Pixels retain maximum sharpness in fast movement with better response time. The white to black can be in the high teens or more on a non TN panel.

Hz makes a massive difference and gets you most of the way there but response time still matters for gaming at least to me.

Having just bought a dell 3007wfp-hc, I cant tell the difference between that and my Westinghouse with 5ms response time. I also think a blind test would yield people not knowing the difference.
