However, my choice then fell on the BenQ, as well as my old, now defective monitor from BenQ was and my experience with the customer were positive. Unlike Acer BenQ offers VorOrt pick-up service.
What else can I say about the device itself? There are factory preconfigured color settings, but which in my opinion not much suck. This, however, I knew already from my old monitor, so that the manual adjustment of color values turned out to be unproblematic. This is done quickly and intuitively on the side of the monitor mounted buttons.
As far as I am so pleased and would make this day the decision to buy again the same way.
