I don't know why this article is showing up everywhere, but this monitor and its competitors from Monoproce, Viotek, Dell, and Samsung (Who makes the panel) have been around since at least March of this year maybe longer! What makes even less sense is that there are new releases of this panel from Asus, Deco Gear, and Spectre!
I own the AOC and it's amazing! It's especially good for racing & flight sims. The HDR 400 isn't as bad as people have claimed in reviews. I have a Samsung Q70R TV so I know what good HDR looks like.
