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. It's a real shame because it's a nice looking monitor, even if managing the screen is a pain in the ass. What a problem.
