Unlike other QD-OLED monitors, e.g. from AOC, the HDR mode works beautifully on this one, with perfectly saturated colors. And everything else works great, nothing is broken, the monitor menu system seems good, the OLED care features are unobtrusive, and the calibration seems to be actually great. Panel uniformity is excellent, haven't seen dirty greys and banding (like on WOLED monitors). The monitor build quality is also completely satisfactory, it feels like a quality product. Even the LED color customization menu shows precisely the color you see in real life on the LEDs.
Based on my experience this is one of those monitors you can just plug in and enjoy, without having to fiddle with settings and try to solve problems for hours. I literally haven't had to change anything, because I'm perfectly satisfied. I wish this was normal, but sadly it isn't.
The monitor lacks speakers, but after trying out two other monitors which had "speakers", I think I'm okay without, because those speakers were unsuably bad.
One final note is that the QD-OLED characteristics of course do apply here, so the monitor has a slight magenta tint and raised black levels in VERY bright environments, it has somewhat reflective glossy finish (to provide super sharp image), there is "text fringing" which means that text is rendered with some off-colored pixels vertically due to the subpixel layout, and the maximum brightness is relatively low (still very bright in moderately lit environments). However, I tested it against a 4th generation WOLED monitor which costs more, and I found this QD-OLED a lot better, in fact even the text rendering is not worse in my opinion.
