Spatial Uniformity
You can see two light leaks in the corners. They were also visible when screening movies.
Despite the disappearance of the filter, the static qualities of the FP91V weren't any better.
BenQ FP91V: No Better, No Worse
You can't fool the sensor. Our test shows the FP91V is not really any better than the FP01V+ despite a claimed gain in latency of 2 ms. The panel is made by AU Optronics - an AU190 ACAL V5.
What you can see most of all is that the monitor lacks precision, which explains the latency peak in the neighborhood of code 150 on this graph. When the transition was of moderate amplitude (black -> gray), it took at least two frames to achieve the desired level.
