The average high frequency rate of similar spec TVs that have been on the market for a comparable time to this TV is 220Hz, and the high frequency rates range from 50Hz to 1,600Hz. With a high frequency rate of only 60 hertz, the 42LN5200 has a fairly slow high frequency rate compared to most of the other TVs that are a comparable age to this television.
We think you might also be interested in some of the alternative 60Hz refresh rate TVs currently available including the Philips 46PDL8908 which has better reviews.
If this LG television high frequency rate is not fast enough for you then you might want to consider the LG 50LB650 (100Hz) which also has a higher rating.
