What is MPRT in Monitor Specifications?

MPRT (Moving Picture Response Time) is a specification that measures the response time of a monitor’s pixels when displaying moving objects. Unlike the traditional response time metric (usually indicated as GtG or Gray-to-Gray), MPRT focuses on how quickly a monitor can refresh images during fast-moving scenes, which directly impacts the clarity of motion.

How Does MPRT Work?

MPRT measures how long pixels remain visible before they are refreshed with a new image. The lower the MPRT value, the less time pixels "linger" on the screen, which reduces motion blur or “ghosting.” This is especially beneficial for gaming and video viewing, where the clarity of fast-moving objects is essential.

The Difference Between MPRT and GtG

GtG response time reflects how quickly a pixel can change from one gray level to another. MPRT, on the other hand, measures the visible duration of each frame on the screen. For instance, if a monitor has an MPRT of 1ms, each frame is visible for 1 millisecond, minimizing blur and making the motion appear clearer.

Why is MPRT Important for Gamers and Video Enthusiasts?

For those who enjoy video games or movies with fast action scenes, a low MPRT is crucial. A lower MPRT value allows the monitor to deliver smoother, clearer motion, which enhances immersion and viewing comfort. Many modern gaming monitors include features to reduce MPRT, often using black frame insertion (BFI) or higher refresh rates to achieve this.
