With a high frequency rate of 400 hertz, the Samsung UE50ES6710Q has one of the faster high frequency rates amongst televisions of this age. The high frequency rates of medium display diagonal TVs that have been available for more than two years range from 50Hz to 1,600Hz, and the average high frequency rate is 220Hz.
It may also be worth also looking at one of the alternative 400Hz refresh rate TVs currently available including because of their better review scores, the LG 42LM670S, or the Samsung UE40ES6800S.
If you want a faster high frequency rate then you might want to consider the Panasonic TX-L42ET60E (600Hz).
