The uniformity frankly wasn't anything to write home about. Uniformity of lighting seems to be a problem on all LCD panels in this format. Here the upper part of the panel was visibly brighter than the lower.
The 200W6's latency results were worthy of an earlier generation of panels. Acceleration hasn't really made a difference.
As you can see, the latency was close to 30 ms. The best reading was 20 ms for abrupt transitions.
