Refresh rate is the most relevant display attribute for reducing perceived motion blur and improving motion smoothness in fast-paced video or gaming. Refresh rate, measured in hertz, indicates how many times the display can update the image each second. A 120Hz or 144Hz display can present more individual frames per second than a 60Hz display, producing smoother movement and making rapidly moving objects easier to follow. Response time also affects ghosting because it measures how quickly pixels change from one state to another, but refresh rate is the broader attribute governing how frequently new frames are displayed. Resolution controls the number of pixels and therefore image detail, not motion smoothness. Color accuracy determines how faithfully colours are reproduced and does not directly reduce blur. For the best result, a high refresh rate should be paired with a low pixel-response time.
