The only program that I thought would be interfering, was Display fusion. but it flickers wether or not that's one. So it certainly could be something else. Guess we'll see with the fresh install.

Hate to bring this back up, but now the second S2726DG is flickering too. Which leads me to believe that I was wrong about my hardware/drivers being the problem. I'm going to be swapping my CPU/MOBO soon, and I'll be doing a fresh install. So that will serve as a Driver issue check. And if that doesn't fix it, I'm looking to get a GTX 1080 in mid January, but that will be the nail in the coffin if it doesn't fix it. I find it rather unlikely that I can buy two different monitors, from two different Best Buy locations, and have the same issue. Sure, it could be a batch problem, but if that's the case, I probably won't get it fixed until they roll out another batch anyways, right? And I just cannot wait that long to replace this thing. Anyone else have any other ideas? I really like this monitor, and I want to keep it. But the entire screen cutting out is a deal breaker.

Turns out I was right. I swapped the display at Best Buy, and the new one has been working great since this weekend. Hopefully it stays that way. really don't want to make a third monitor exchange. -__-

Quick update. Tried running the monitor at 60hz on HDMI. No flicker. So it's either the cable or the monitor itself, at least as far as I can gusss.

I do keep it at 144hz. I did try downshifting to 120, but oddly enough that brought the flicker into games. 144 doesn't flicker in games, and 120 flickers slightly better in desktop, but terribly in games. Which revision do you own, if you don't mind me asking? Also, did you install the latest driver for the monitor from Dell, or did you just plug and play?

Oh! One more thing. I did briefly try the ASUS PG248Q before this, and it also worked just fine. in desktop, and in games. The only reason I exchanged it for the S2716DG is because the colour looked washed out no matter how I calibrated it. And given that I would be making the jump to the 1070/80, I figured I could go ahead and bump the resolution and be more than fine.

Hi guys, I purchased the aforementioned monitor less than a week ago. Got it home, hooked up, and calibrated, and everything looked great! Until I noticed occasional black flickering when on the desktop. It doesn't do it in games, but on the desktop I get intermittent black flashes on the screen that don't last for more than a second or so. I've had two 1080p monitors before this that never had any such issues (They were 60Hz, BenQ monitors. Not sure about the model number), and I'm a little frustrated at this point. I still have one of them set up next to the S2716DG, and it's just fine. I've already done some digging, and it looks like it could be a few different factors. The monitor itself (though, there don't seem to be many documented cases of this for the particular monitor.), the included DisplayPort cable (previous and secondary monitors were/are on DVI cables.), my GPU (not likely in my mind, because as I've said, it was working fine with my older monitor. But I'm well aware that I could be very wrong here.), and finally the drivers (again, the least suspect to me due to everything running just fine before this monitor. But I do realize that there could be some driver issues that arose when the monitor's drivers came into play.). As for specs of the relevant hardware, to try and help narrow things down: AMD XFX R9 390 (planning on updating to the 1070/80 later, that's why I bought a G-Sync monitor), and the monitor is the Revision A03. Monitor and GPU drivers are up to date on the newest versions at the time of writing. Any input before I go swapping cables, clean installing drivers, updating my GPU early, or exchanging the monitor would be greatly appreciated.
