Either I have a bad block or the monitor is not compatible with a 2015 Macbook Pro. Worst of all, when I tried to get support, they tried to blame the Mac. The previous big monitors I've used are Macs (some Acers too), everything worked fine. I've already tried 3 cables on 2 different ports (Displayport and HDMI) so I have to return it. Too bad, because it's a good-looking monitor, even if the on-screen controls are annoying. What a problem.
