Just found a comparison video, showing the "new" feature of the 2735 called "Dynamic Accuracy":
imo what you can see in the video is complete BS. A normal 2730 doesnt have so much ghosting as seen in the video, especially at 280fps as can be seen in the video.
The example in the video looks like they completely disabled overdrive on the 2730 (AMA off) and on the XL2735Z overdrive is enabled (AMA high) and ON TOP of that, the BenQ Blur Reduction is also enabled (BBR), which in that case would literally be a completely imbecile example to start with.
What I think this "new feature" Dynamic Accuracy really is- its a slightly improved BBR (BenQ Blur Reduction) with slightly less crosstalk and Ghosting and whatnot. Its most likely really nothing to drive home about.
The XL2735Z is hardly a "real" upgrade to the 2730. It still has 144hz, so they didnt even bother to overclock the panel to 165hz, which even the DP1.2 standard actually supports, like the recent Gsync IPS 1440p monitors have it. Despite the argument if the difference is actually noticable (144->165), if its technically possible, I think they should include this for ppl to have a choice. Id gladly use 165hz over 144hz if my XL2730Z supported it without any downsides like the PG279Q which has poorly implemented 165hz, with response times beeing worse than @144hz.
Anyways, looks like BenQ is actually lacking behind Asus and Acer in terms of new gaming monitors. It still doesnt have a 144hz(165hz) IPS monitor afaik and, still no slim bezel design, nothing new in the 2735. Looks like Asus and Acer will split the gaming monitor market between them for the most part, plus a small share for AOC here and there. BenQ is basically AFKing in the last 2 years.
