TVs that have been available for more than a year have high frequency rates of between 50Hz and 3,000Hz, and the average high frequency rate is 520Hz. With a high frequency rate of 1,000 hertz, the TX-49DX650 has a fairly fast high frequency rate compared to most of the other similar spec TVs that have been available for around the same time as this TV.
We think you might also be interested in some of the other 1,000Hz refresh rate TVs currently available including because of its better review score, the Sony KD-65XD9305 (£1,199.99).
If this TV high frequency rate is too slow for you then you might want to consider the LG 86UH955V (£5,990) (2,700Hz).
