BenQ FP91V+: Power Is Nothing Without Control
This model came close to taking the prize for the most reactive monitor. But its lack of accuracy in certain transitions betrayed it, as you can see here.
The monitor was very accurate in moderate transitions. On the other hand, the latency literally exploded in wider transitions (0->200, 0 -> 225). That can be blamed on the overdrive, of course. Sometimes it took more than two frames for the display of the requested color to stabilize. In the meantime, the color was too bright.
