I also tried to run Chrome with all extensions disabled, but it didn't help. However, WITH the docking station, the external screens go black - even if only one is connected or similar (I tried a lot). Further, the issue only happens when using my docking station: if I only connect one screen directly to my laptop, the issue does not appear. If I use my laptop's screen as a third screen, the two external ones go black, while the laptop screen stays fine. I've updated all drivers, especially around my laptop's graphics chip, and including things like BIOS, without improving the situation.

Music starts in between, PC reacts normal, only the screens turn off and on continuously. Though, the really bad thing is: as soon as I hit PLAY in Spotify, the same thing happens, though not only 3 times, but continuously (okay.I never let it run more than a few minutes, as I have to work here).

During the incident, I can still access/navigate my PC normally - it only seems to affect the screens. After these 3 iterations, the screen is back normal. During that, they stay black for maybe 3-5 seconds each time, come back for 1-2 sec, then go black again. When I open the homepage for the first time, my two screens are flickering or to be precise: they turn off and on for about 3 times. 75 64-bit), but the same thing happens with MS IE Edge.
