Could the non-flickers have Variable Backlight: Mode 2 active? I noticed it's bearly visible in mode 2, but modes 0 and 1 have clear dark grey flicker.
Edit: Mode 2 seems to have a hidden bonus level: left and right side of the monitor flicker when taking cursor from edge to edge, has anyone succesfully used HDR on this monitor? :D
Um... I tried all 3 modes but didn't really see any difference with regards to flicker in Windows.
I've left it on mode 0 for a good while now and pretty much got used to the flicker. Might give mode 2 another shot...

They do seem to be cable sensitive, probably because of the fact that they push DP bandwidth the the max, and maybe the Gsync module on top of it. I had some minor, intermittent issues with mine after I got it over my very lengthy (20') DP cable so I decided to get a fiber optic one and that solved the problems.
Today my flicker returned even with the new purchased cable. Guess I have to try fibre optic too.

I've been using it for a while and the only issue I have is that my GPU doesn't wanna run such a large resolution. There is considerable lag, un-responsiveness, YouTube vids go black (need to minimize to refresh) since moving to this.

Running a 980ti.

I didn't notice this till now (because it went to my spam folder), but Dell released a tech memo a few days ago about AW3821DW flickering.
