PLEASE ATTENTION
Do not update to version 1402.6, it will brick the monitor in an unreversible way, causing blackscreens that will last until the cable is unplug.
They broke something with the G-Synch that causes this.
I'm not alone, in the Samsung forum multiple people are having the same experience and so far the Samsung support has refused to help.

Crap, unfortunately I read it too late. That's exactly the problem I have now ;(

Answer

I have black screens and artefacts from time to time with firmware 1402.6. By changing the video connectors, I no longer have any problems. I had dp2.1 now hdmi 2.1. I hope Samsung is responsive with these updates. I prefer the display port.
