Someone also asked this question so I'll just copy and paste that answer.



Like most TN panels, it's probably 1ms minimum with 6ms maximum, and a average of 3-4ms response time. The 1ms specification is only the lowest possible response. The panel doesn't operate constantly at 1ms. It definitely isn't 8ms because that would cause massive motion blurring at 144hz (the monitor would be unusable). The overall response time (from controller/mouse input to graphics card to screen) is probably a bit higher than 10ms which is considered excellent, because the world record is 8.5ms. All of this is conjecture but should be within the ballpark for 144hz TN monitors.



Keep it mind that at this level of response time, your internet connection affects your gameplay a lot more than this monitor would ever do.
