Im getting the ISF calibration disc I will post numbers after Ive used it. Im still not sure about this TV. I like the picture so far but it makes a loud buzzing noise when you first turn it on and then seem to get quiet. The owners manual and box that came with the tv says its 1,000,000 to 1 dynamic contrast ratio with a refresh rate od 6.5ms, if you look this TV up on the Vizio web site it says 100,000 to 1 dynamic contrast raito and that it has a refresh rate of 5ms, and if you look under the suport tab on the same page and down load the manual it says 1,000,000 to 1 dynamic contrast raito and a refresh rate of 5ms. All this really dosent matter as I said I like the picture, but Vizio really needs to get their act together on the stats as alot of people like to compare them and I called them and the person on their tech line couldent tell which was right.
