What is 1ms response time? Response time in monitors refer to the amount of time a pixel (dot) takes to go from black to white and back to black again. It is measured in milliseconds (ms). The lower the number, the faster the pixels can change, reducing the ghosting or streaking effect you might see in a moving or changing image such as in games and movies. Common response times range anywhere from 14ms to 5ms. Monitors that are designed for faster applications feature response times as fast as 2ms. These monitors are ideal for gamers, video enthusiasts, engineers and movie production houses. |  Slow (higher) response time |  Fast (lower) response time |
