Gaming: response times and input lag
Input lag and response times are important for those who likes gaming. In this case, we are not discussing gaming monitors, so it is not as crucial to score well in this test. There is, however, still quite a difference in the time it takes these screens to change pixels.
In our gaming monitor tests, we show both the rise and fall times separately and combined in both default mode, at maximum overdrive and at optimal settings. The optimal overdrive values are defined as combined rise and fall times of as close to 16ms as possible or lower with as little overshoot as possible. For example, a response time of 4ms with an overshoot of 60% is less desirable than a response time of 15ms with 5% overshoot. Overshoot and undershoot are what creates the annoying artefacts around the moving objects. Especially in contrast changes, you can notice a thick glow of white to black or the other way around. Those are, in our opinion, more annoying than a light ghosting.
In the case of non-gaming monitors, we limit this to the combined rise and fall at maximum and optimal overdrive. On our product pages, you can always find the split results as well.
It comes as no surprise that the IIyama G- Master G2530HSU-B1 leads with its TN panel by a long shot, at least at optimal overdrive. It is also the fastest without overdrive. For those who would prefer a stylish IPS panel screen, the choices are not limited. It seems Samsung’s VA panels lag behind even with overdrive. As you maximise the settings on them, the over and undershoot becomes more visible and we would not recommend that. The de AOC PDS241, BenQ VZ2470H and the Acer RT240Y would also not be high on our recommended for gaming list.

There is no much to say about the input lag. A few models have visible input lag, a few others are a couple of milliseconds slower than others. None of this would be a deal breaker for non-gaming.
