    I tried with SLI disabled, and even removed the bridge and swapped cards over to make sure it wasn't the cards causing the issue, but still had a flicker on windows and dodgy text. Like I say, I used it perfectly for 2 weeks before the problem just appeared - no driver updates in that time. Even though I have reinstalled since to just triple check everything. I just hope once Scan receive it, it shows the problem at their end then I get charged for shipping and collection on the rma. I now have my old 1050p screen connected and everything is back to normal... its horrible going back to 22"!!

    I`ve got a "high-end PC" GTX 780ti SLI, Intel 4960X etc....so the PC has surely no performance issues.

    in other words: The monitor should work "out of the box" with this config.

    The problems seems to be "gsync module" related....
    However, i sold all 3 monitors last week and my problems are gone

    This issue is definitely related to using the G-Sync module.

    I've head some people had luck uninstalling certain programs, but I've had no such luck.

    I can confirm that uninstalling RivaTuner, doing a clean install of drivers, and using the PG278q monitor profile/driver from ASUS does NOT fix the back-light flickering problem with G-Sync.

    I'm using a GTX780ti, but I will be testing it with a GTX680 just to be sure.

    Repeating this method again since it seems to be a solid way to reproduce the issue:
    Open up CS:GO
    Press Shift+Tab and open up the web browser.
    Go to a bright website (like nytimes.com)
    Scroll up and down

    It also was occurring at 90+fps. If the next driver update doesn't fix it, this monitor is going back. Something that cost $800 should not have these kinds of issues with its KEY feature.

    UPDATE:
    I reconnected my VG248QE w/ G-Sync module to try the same test. Lo and behold, the same issue happens on that screen too!

    Hopefully Nvidia fixes this in a new driver soon.

    Same problem here. CS:GO with G-Sync is flickering. Without - it's fine. The thing is - the first few days I didn't see it, and then it start to manifesting more and more! Tried another DP cable - same propblems.

    Intel i5 2500K, 8Gb RAM, ASUS Nvidia Geforce TITAN, WIn7x64.

    Thanks guys for these posts! I am having the same problem and thought I was the only one!

    Does anyone know if it's a driver issue or a panel issue? I can take mine back and swap it for another one. However if I'm just going to have the same problem I'd like to same myself the trip.

    Currently turning off G-Sync has sorted the issue, but as others have said. Very hard to justify a $1,000 TN Panel without G-Sync

    Sys Specs:

    Intel 3960x
    3-way SLI EVGA 780 Classified
    16gb RAM
    Both Windows Technical Preview and Window 8.1 tested.

    Well, it's flickering even without g-sync on mine, but only after a few hours of playing. It was even flickering in BIOS once so I doubt it' a driver issue.
    Intel i5-2500K // ASUS Sabertooth P67 MB (BIOS 3602) // 8GB RAM // ASUS Nvidia Geforce TITAN (BIOS 80.10.39.00.0A) // Windows 7x64 with all latest updates and drivers // ASUS ROG SWIFT PG278Q // ASUS RT-AC68U
