Just got my new EVGA RTX 3080 XC3 yesterday from Microcenter and it's causing my monitor to black screen, and flicker a wide black area into my secondary portrait screen. I've never seen anything like this before and after reinstalls/clean DDU of the newest driver for my new GPU, changing DP cables, AND an OS wipe it's not fixed. I decided to go back to my EVGA RTX 2060 Super Black and absolutely no issue even on newest Nvidia driver so we can remove that as the cause. The seems to only occur when using G-Sync (G-Sync Compatible.) My main display is Nvidia certified G-Sync compatible LG 27GN950-B (4K 144Hz G-Sync Compatible) and uses DSC DP 1.4 for full color. My second screen is not certified but G-Sync compatible still works perfectly with my old RTX 2060 Super. As soon as I turn this on it causes my main LG screen to flicker on and off randomly black screen. My secondary with then have a weird black bleed over that flickers on the screen and grows and begins to cover the screen in black. It also causes the secondary screen to randomly go very dim. Then it all flickers back to normal and then repeats. It is also affected by moving windows around on the screen or going full screen in programs. It's all very odd. I have tried disabling adaptive sync on my secondary screen, but then G-Sync turns off on my main LG display even though it's selected in the Nv control panel (confirmed through OSD not changing refresh rate with FPS changes) If I then tick the box that allows you to turn on G-Sync even if not certified G-Sync will work again but I get the same issue and my screen blacks out randomly and my bleeds to the secondary screen. I am pulling my hair out on this one as I have now been using my 2060 Super again with no issue at all. All signs point to the new EVGA RTX 3080 being faulty or having a big vBIOS issue. Any help EVGA? Edit: Updating as I just found this thread.. Looks like there is some issue with G-Sync/G-Sync Compatible with RTX 3080. Some now reporting issues with their 4K 120Hz LG OLEDs. Also reporting they had no issues with old cards. Great.. https://www.nvidia.com/en-us/geforce/forums/support/398630/4k120hz-not-working-with-3080-and-lg-c9-when-g-syn/

What PSU are you running? How many Watts? Is it modular? Are you using 1 cable with a splitter or 2 individual 8 pins?
Edit: Also what Hz are the monitors set at?

EVGA 1600w T2 with 2 separate 8 pin cables. Never had an issue, the PSU is only about 1.5 years old and worked perfectly with my RTX 2080 Ti FTW3 Ultra as well. I don't think that is the issue here. Both monitors are set to 144Hz which is native for both.

Sounds kinda like a Gsync driver issue, like they have had before.

Have you just tried 1 screen first to see if it's an issue? If it's fine then reboot and while the system is running then connect the other?

Just for clarification, if you have gsync or any of the sync stuff off, everything works fine? Edit: On a side note, regardless of how amazing gsync is and how much I love it, I personally stopped enabling it because of the input lag it can cause.

Possibly. But then I would expect that to persists across to my RTX 2060 Super which it's not and is working perfectly. Unfortuantely we have one driver to test right now. vgerik1234

Yes both monitors work fine with all adaptive sync/G-Sync turned off. If turned on with the RTX 3080 I get flickering to secondary screen and my main LG display will black out randomly even on the desktop and it happens every few seconds or radomly. If turned on with the RTX 2060 Super it all works flawlessly.

Ya first time ever having a problem with G-Sync in 4 years. My old Dell and Acer both had real G-Sync modules and never once did I had a flicker or black screen issue on any driver. Now with this new monitor not having the real deal inside and using adaptive Sync/ Free Sync/ G-Sync Compatible is showing me just how trash it is in comparison to the real deal even if this is the first time I've had a snag with it. Nvidia better have a fix quick. Good thing I took the 4 year replacement warranty from Best Buy.

Jesus, the cards have barely been available 24hrs and you're upset there's a minor g sync issue with them that they'll undoubtedly fix? Lol....

Honestly, a simple update can be probably be pushed - hopefully soon :( Have we figured out if it's just "G-Sync Compatible" or true G-Sync monitors as well?

I'll do a test with my real G-Sync monitor soon. I am willing to be this is a G-Sync compatible issue, a program which is really proving to be trash. Look at the G7 and it's issues that still have not been fixed. Nvidia and the monitor companies need to go back to offering full modules or nothing.

Hello! OMG I actually have the same issue. I too have DDU and tried so much. The issue goes away when GSYNC is turned off. I actually have a Gigabyte 3080 and a LG B9. Whenever the instant game response message is displayed the screen goes black and I loose signal input.
It certainly does seem like a driver issue

Likely just the brand new cards with their bugs and kinks that haven't been patched yet. Hopefully some driver updates solve it soon.

Just posting to report the same. I have the same monitor and a 3080. The latest drivers made it worse and I'm unable to stop the black screen flashes unless I set it to 1080p even with GSYNC disabled. So I'm running 456.38 with GSYNC disabled just to be able to use my machine. Has anyone tried out the latest drivers and seen any different?

This is an a$$ thing to say but reading about the issues with the cards and drivers does make the lousy release of the RTX30XX sting a little less.
Assuming I ever lay hands on one, or chose to buy one when they're available, the drivers and hardware ought to be mature.

I hooked my RTX 3090 XC3 up to my LG CX 48” and had these exact same issues. Screen flickered black over and over. I’m glad to see the problem is the card and not my tv or cable though. Hopefully they get a fix soon. Disabling Gsync seems to fix the issue.

 I almost bought one for delivery on Saturday, but decided to hold off - Black Friday is right around the corner. Also - Jacob, I've not heard back in 2 days about that email conversation. I can guess that you're busy, but please get back to me when you can.

Thanks for the info Jacob. Unfortunately this isn't one of the models listed by LG as needing fixed and they've never released a firmware update for it as far as I'm able to tell. This device is actually a 27" 4k 144Hz monitor and not a TV nor is it OLED. I think its a separate issue. Tested the latest drivers just now and still seeing the same thing, monitor blanks out as well as half of my second monitor every 15 seconds or so, then comes back on with Gsync enabled. No problems with it disabled.

Yes the issue is still present even with the newest drivers. But I have discovered what seems like a temporary fix. My secondary monitor is 144Hz IPS 1080p display that is set in portrait mode. I set the secondary screen to 120Hz instead of 144Hz and the issue resolves itself. I can use G-Sync on my main LG monitor, with no more blanking or weird half my secondary screen being covered with flickering black.

An updated firmware has been in development with plans for a roll out within the next few weeks to LG's 2020 and 2019 HDMI 2.1 capable TVs, which should address these incompatibility issues. When ready, additional information will be available on the LG website and in the software update section of owners' LG TVs. We apologise for the inconvenience to our loyal customers and thank them for their support as we continue to push the boundaries of gaming technology and innovation.”
Thanks for the info Jacob. Unfortunately this isn't one of the models listed by LG as needing fixed and they've never released a firmware update for it as far as I'm able to tell. This device is actually a 27" 4k 144Hz monitor and not a TV nor is it OLED. I think its a separate issue. Tested the latest drivers just now and still seeing the same thing, monitor blanks out as well as half of my second monitor every 15 seconds or so, then comes back on with Gsync enabled. No problems with it disabled.
Yes the issue is still present even with the newest drivers. But I have discovered what seems like a temporary fix.
My secondary monitor is 144Hz IPS 1080p display that is set in portrait mode. I set the secondary screen to 120Hz instead of 144Hz and the issue resolves itself. I can use G-Sync on my main LG monitor, with no more blanking or weird half my secondary screen being covered with flickering black.
What an odd workaround but this definitely worked. Thanks!
Nice! Glad I could help.
Which monitor are you on again? Sorry if I missed it somewhere in the post.
LG 27GN950-b 4k 144Hz is my primary and I've got an Acer 1440p 144Hz as a secondary.

Had the same issue with the same monitor (Nvidia FE 3080, LG 27GN950-B, Dell 2716DGR). LG was flickering. Turned the 2716DGR refresh rate to 120Hz, and 144 is working perfectly on the LG now.

Here is same issue.
My monitor is LG 38GN950G and I am using G-Sync for window and full screen.
Black screen issue happened to me when I watching video in Youtube which is totally under performing status.
Not OC my 3080 FTW3 Ultra yet but update bios. I am using 1000W EVGA G5 fully modular power.
The symptom seems like display change. You know, when user manually change the display it disconnected from current screen and turned out to black and if you do nothing, the video and sound is came back about 30 sec. The thing is, I am using DP cable and my sound system using Optical out from main board. I am not using HDMI.
This monitor has NO problem with my old GTX1060 for a 10 month but currently with 3080 FTW3 Ultra, it happening one or two times per day.
Jacob said, LG "plans for a roll out within the next few weeks to LG's 2020 and 2019 HDMI 2.1 capable TVs, "
I am not sure this is include my monitor as well.
For make sure G-sync made this problem or not, I will turn off the G-sync for a while and will see this issue gonna happened or not.
