The 40L1534 has one of the slower high frequency rates (only 50 hertz) amongst medium display diagonal TVs of this age. The high frequency rates of TVs of a comparable age and spec to this TV range from 50Hz to 1,600Hz.
We compared this TV to all the other 50Hz refresh rate televisions and we think because of its better review score, the Toshiba 40L3453 is also worth considering.
If this Toshiba TV high frequency rate is too slow for you then you might want to look at the LG 49LF5400 (60Hz) which also has a higher rating.
What does "high frequency rate" mean?
