The UE40F7000AT has a fairly fast high frequency rate (240 hertz) compared to most of the other similar spec TVs that were released around the same time as this TV. Across all the medium display diagonal TVs that have been available for around the same time as this TV the high frequency rates range from 50Hz to 1,600Hz.
We think you might also be interested in some of the alternative 240Hz refresh rate televisions currently available including the Toshiba 46WX800U which has better reviews.
If this Samsung television high frequency rate is too slow for you then you might want to look at the LG 47LA691 (400Hz) which also has a higher rating.
What does "high frequency rate" mean?
