With a high frequency rate of only 100 hertz, the LG 49UH668 has one of the slower high frequency rates amongst similar spec TVs of this age. The slowest high frequency rate of 4K and 8K TVs that are a comparable age to this TV is 50Hz, the fastest is 3,000Hz, and the average high frequency rate is 520Hz.
We compared this TV to all the other 100Hz refresh rate TVs and we think cheaper TVs such as the 55UH668 (£489.99), and the 43UH668 (£499) both from LG or the Sony KD-55X8509 (£429.99) are also worth considering.
If you are looking for a TV with a faster high frequency rate then you might want to look at the Sony 55W809CBU (£449) (1,000Hz) which is also cheaper.
