This is why you might want to spend $700 on an FHD monitor. That 3ms screen draw time is something you can easily see in practice. When objects move on screen or the camera pans, resolution remains at its maximum. No amount of motion, at any speed, can cause blur or breakup of the image on the PG259QN. While the other monitors here are close in numbers, the PG259QN truly appears to be in a class by itself.
Input lag matches the record-holding Samsung at just 18ms. No gamer of any skill level will perceive control lag when gaming on this monitor. At this moment in time, it doesn’t get better.
