With manufacturer's starting to produce 240Hz HDTVs, I would have to believe that a good portion of them are TN panels, since those are the only one's I've seen get down to the 4ms response times that would be required. Walking around Best Buy the other day, and realizing this fact, I was impressed with the viewing angles that the TVs had, and began to wonder why viewing angles on TN-panel based monitors are so horrible in comparison.
