Maverick Jester - Unfortunately not. As usual, since it's a South African model, there's limited to no information available off the Samsung site, and no reviews. Not even customer ones.
I have seen one Samsung ZA TV that listed both refresh rate and response time in a table, but none of the others I've seen do, which is rather annoying.
I know plasma has like 0.001, and that some LEDs have good ones, like 5ms. I have read reviews of LEDs that have 12ms though, and that's just not good enough for gaming.
Hopefully Samsung sends me the correct information shortly.
