Blur Busters has detailed its findings of a unique ZisWorks display that utilizes a custom FPGA board to achieve 120Hz at 4K, along with “bonus” refresh rates such as 240Hz and 480Hz at 1080p and 540p, respectively. The first round of tests discusses the advantages of super high refresh rates, which include reduced phantom array effect, motion blur, and input lag. The site will be releasing tests on the latter next week.



Going to higher refresh rates can have diminishing points of returns. Humans cannot see individual frames at 480 Hz. However, humans can see other side effects of non-analog motion (discrete frames to represent moving objects). Many researchers including Oculus’ chief scientist Michael Abrash, extoll the benefits of quadruple-digit refresh rates. So even 480 Hz is not the final frontier yet.
