how can a monitor have a 1ms response time when the refresh rate isn’t 1000Hz?

My computer monitor advertises a 1ms response time and the refresh rate is 144Hz. Wouldn’t that mean that the best response time possible is 1/144s?

The refresh rate is how many frames it tries to show each second. The response time is how long it takes to go from one frame to the next.

`1/144Hz = 6.9ms`

`1ms / 6.9ms = 0.144 = 14.4%`

With the numbers you gave, the monitor is going to repeatedly spend 1ms transitioning to the next frame, then 5.9ms staying still on that frame. So it’ll spend 14.4% of its time transitioning and 85.6% of its time showing you the image.

If the monitor had a 1000Hz refresh rate and a 1ms response time it would always be transitioning. It’d never stop to show you an image. You’ve done a reasonable calculation in your head, but you thought it was a minimum when it’s actually a maximum.
