Gaming: response time and input lag

Now the part where the gamer is of course most interested in: the response time, or the time it takes for a pixel to change colour. We measure both black to white (and back) as well as dark- to light gray (and back again). 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 standard response time of the AOC AG241QG and AG241QX are pretty good. For 144Hz a time of 6.94 ms is necessary (1000/144). Without overdrive both come reasonably close, but the rise-times are slightly too high. With maximum overdrive we see times that are a lot faster, but also a severe overshoot - especially the 104% overshoot of the AG241QX with this setting is very undesirable. It is important to find the optimal mode - 'medium' turns out to deliver excellent results. The AG241QG ends up very high in the graphs and the AG241QX is also fast enough - while it barely shows overshoot here, the G-sync counterpart has more overshoot and therefore more artifacts.

Input lag

Finally the input lag, or the time between sending the signal to the monitor and the moment that it is visible. For both models it is well below the 16 ms that we view as troublesome; in comparison with a CRT-monitor we do not see any noteworthy difference. With the Leo Bodnar tester the AG241QG shows marginally more input lag, but in comparison with the competitors it is not excessive.
