Response time of a monitor is the time for a pixel to response to the input signal, or the time it takes for a pixel to change going from black to white to black again (by applying electric voltage to a layer of liquid crystal, thereby inducing changes in its optical properties). The “1 MS” that users usually see on a monitor spec is referred to the response time of the monitor. In terms of the monitor response time, the lower the better; meaning that a moving image will creates lesser “blurring” or “trailing” effects on your screen. Response time is generally measured using MPRT (Moving Picture Response Time) and GtG (Grey To Grey) methods.

Definition of MPRT and How to Check MPRT Response Time for Your Monitor?

Definition of MPRT
MPRT or Moving Picture Response Time, is a technology to reduce motion blur. Monitor with MPRT disabled the backlight during picture changes and enable backlight again after the picture had changed. This reduces the time of a frame showing on the monitor, therefore reducing “ghosting” and “blurring” effect, picturing visually smoother image while playing games. In short, MPRT is a solution to reduce “ghosting” effect effectively during gaming.
