Como pode ter uma frequência máxima de tempo de resposta de 66,67 Hz e uma taxa de atualização de 144 Hz?
This does not make any sense!
Isso porque eles estão medindo coisas diferentes:
"Response time is how quickly the display can have a LCD pixel to change from fully active (white) to fully inactive (black), then back to fully active again. A lower response time typically means less ghosting of the image and better picture quality."
This differs from refresh rate, which is how many times per second the panel can redraw the image. With refresh rate you want a higher number, response time you want to go lower. It's measured in milliseconds, so a 5ms response time means that a monitor can go from white to black to white in 1/200th of a second.
