At only 50 hertz, the 42LY330 has a quite slow high frequency rate compared to most of the other medium display diagonal TVs that have been available for more than two years. The high frequency rates of medium display diagonal TVs that were released more than two years ago range from 50Hz to 1,600Hz.
There are a number of alternative 50Hz refresh rate televisions currently available that you might want to consider including because of its better review score, the Samsung UE46EH5000W.
If you are looking for a television with a faster high frequency rate then you might want to look at the Philips 40PFS6909 (£499.99) (60Hz).
What does "high frequency rate" mean?
