Iiyama G-Master Silver Crow GB2783QSU-B1 review: gaming with a silver crow

Excellent choice for budget gaming at wqhd-resolution


Gaming: response time and input lag 

Of course the G-Master Silver Crow GB2783QSU-B1 is primarily a gaming monitor, so you might have gone straight to this page. If you do not want to look at all the graphs: it is a fast monitor, perfectly suited for fast games.

If you do want to take a look at the graphs: we continue our experiment and show 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

With the GB2783QSU-B1 we see that standard the black-white transitions are pretty fast, but the darkgray-lightgray transition could use a boost. At maximum overdrive the silver crow performs the best, but the overshoot is way too high (87%). At the optimal setting it ends up in second place, with a lot less overshoot than the number one. We think the ProLite B2783QSU-B1 is slightly better in some aspects (slightly less overshoot, 0.2 ms slower for a double transition).

Input lag

Here we find that in terms of response time the Acer, that is just as fast, has input lag in one of the two previous tests; the GB2783QSU-B1 does not, even in comparison with a CRT-monitor.
