What is Maximum refresh rate in Hz?

Maximum refresh rate in Hz tells you how many times a monitor redraws each second, and a higher number makes fast motion look smoother. The figure here is the ceiling each seller reaches across the monitors they list, not the rate of a typical model. AOC and ASUS sit at the top with 720 Hz and 720 Hz. ALTERNATE's listings land at 540 Hz and 500 Hz, while Arzopa's portable monitors reach 180 Hz. Competitive players gain most from the top rate; for office work the lower figure costs you nothing.
