With a high frequency rate of only 100 hertz, the 55UH668 has a quite slow high frequency rate compared to most of the other TVs of this spec and age. The high frequency rates of 4K and 8K TVs that were released one year ago range from 50Hz to 3,000Hz.
We compared this TV to all the other 100Hz refresh rate TVs and we think the Sony KD-55X8509 (£429.99) which is cheaper; or the LG 49UH668 (£499) which has better reviews are also worth considering.
If this LG TV high frequency rate is not fast enough for you then you might want to consider the Sony 55W809CBU (£449) (1,000Hz) which is also cheaper.
What does "high frequency rate" mean?
