Gaming: response time and input lag

By no means all of the 32-inch QHD monitors discussed are gaming displays, but we did perform tests on all of them at the same extended response time, and we show them below so you can see both the rise and fall time separately, along with the combined values. We perform these tests in standard mode, with maximum overdrive and at the optimum setting. We define the optimum overdrive values as the lowest possible combined risk/fall response times, which are also accompanied by the lowest possible overshoot. In other words: a response time of 4 ms and an overshoot of 60% is less desirable than a response time of 15 ms and an overshoot of 5%. Overshoot and undershoot cause disturbing artifacts around moving parts of the image. Particularly with high-contrast colour transitions, you can then see thick white or black borders. In our opinion, these are more disturbing than light ghosting.

Who wants, can view all in detail, we discuss here only the optimal settings. We also see the best performance with the AOC AG322QCX, LG 32GK850G-B and the Samsung C32HG70QQU when looking at grey-grey transitions. The LG 32GK850G-B is in first place (at a large distance) at what we consider to be the less important black and white transitions, and the two BenQ models do the best. The AG322QCX is not doing as well here, which is mainly due to the relatively long rise time of 10.9 ms. The Samsung C32HG70QQU comes out at 8.7 ms. Black and white transitions remain difficult for VA panels, although there are exceptions.

Input lag

In the input lag measurements we see three models that show a delay of 32 ms compared to a CRT screen and are therefore not the best choice for gaming as far as we are concerned. The Samsung C32H711Q has a 16 ms delay, or one frame at the 60 Hz frequency - acceptable to us, but for gaming we would be more likely to look at the C32HG70 of the same brand anyway. That does show in our Leo Bodnar test that there was relatively much input - but there is probably a delay here because of the upscaling (the test signal is Full HD) and the HDR processing - the fact that we do not see this in the CRT equation is telling.
