Imho, the lack of reviews is casused byt it living in shadow of its bigger brother, the 34UC97, which even Linus strongly recomended. So if it's the same panel (only smaller), aside of it having some backlight bleeding, it scream quality. But I can't find the information to confirm this, the thought is based only on it being the same model number.
As to VESA mount, in some regions, it is included in box, in some it isn't. Yet again, I cannot find the information about regions in which it is included.
