I've tried plenty of Samsung monitors (including this one), and almost every last one of them had issues. Connection issues, flickering issues, and etc.
The ONLY monitor than ran flawless for me (which I still have and use) is the Odyssey Neo G9 49', I love this monitor. But I wouldn't even recommend it, cause a friend of mine had the same monitor and had nothing but issues with it (which I tried to fix for him), and online reviews are seriously bad. I guess I got lucky with mines.
I recommend staying away from Samsung monitors.
Dell and BenQ are my favorite brands, which I also use.
