Got a pair of them myself a couple of years now, and Loctek monitor arms. Never go back to flat.I have the LG 34' curved monitor and it usually works well.
I am not sure if it is due to HDMI or what, it is not flickering but it sometimes goes dark like it is disconnected and in 2-3secs goes back on. Not sure why it happens
No black out issues of any kind ever.
