Gaming: response time and input lag
We show, in a manner of experiment, both the rise and fall times separately, as well as the combined values. We also show the maximum and optimal overdrive results. The optimal overdrive values are combined rise / fall response times of 16 ms or lower with an overshoot that is as low as possible. In other words: a response time of 4 ms and an overshoot of 60% is in our opinion worse than a response time of 15 ms combined with an overshoot of 5%. After all, overshoot and undershoot result in annoying artefacts around moving parts of the image, mainly with contrast-rich gradients you can see thick white or black edges. In our opinion, these are worse than light ghosting.
The new LG 34UM69G-B does not perform great here, even with maximum overshoot. The best results are shown by the Acer Predator Z35 and the AOC Agon AG352QCX, with the Benq XR3501 in third place.

We do not see significant input lag with any of the current models.
