At only 100 hertz, the UHD55B6000 has a quite slow high frequency rate compared to most of the other comparable spec televisions that were released around the same time as this television. Across all the similar spec televisions that have been around for a comparable time to this TV the high frequency rates range from 50Hz to 3,000Hz, and the average high frequency rate is 840Hz.
It may also be worth also looking at one of the alternative 100Hz refresh rate televisions currently available including because of its better review score, the Sony KD-55X8505.
TVs with a faster high frequency rate that might be worth considering include the TX-50CX680 (£349.99) (200Hz and higher rated), or the TX-40CX680 (£449.99) (200Hz and higher rated) both from Panasonic or the Haier LE42H6600 (120Hz and higher rated).
