S2716DG, RTX 2080, blinking black for split second

Question

I have the revision A07 S2716DG monitor bought less than a year ago. I have upgraded my GPU to RTX 2080 recently with NVIDIA driver v.416.34. I have only encountered this after upgrading the GPU. I had a GTX 1070 before without any issues. How to troubleshoot/fix this?

* The fact that you did not have this issue when using the GTX 1070 points to the culprit has either the RTX 2080 or its driver.
* How was the S2716DG connected to the GTX 1070 using what port and cabling on both?
* How is the S2716DG connected to the RTX 2080 using what port and cabling on both?
* Have you reset the S2716DG to factory defaults in its menu?
* Have you tested all Hz? (60Hz/85Hz/100Hz/120Hz/144Hz)

Can you recommend a driver I should be using? • I don’t have a different DP cable at the moment but I will buy once I’ve exausted all troubleshooting steps. • Does the cable that comes with the monitor have issues if I plugged it the other way around (I’m thinking it doesn’t make a difference).

Just spoke with the Monitor team. We do not currently have any of the Nvidia RTX video cards in the lab.

Please post the issue, troubleshooting, all of your hardware, OS, drivers, etc. on the Nvidia RTX forum.

All good steps. Cable direction should not matter.

There are four Windows 10 64-bit drivers here doing a Manual search. (416.34, 416.16, 411.70, 411.63). You may need to test them all. Start with the oldest one.

Did you ever fix this problem?  I have the same scenario (RTX 2080 with S2716DG), though with the Dell monitor as my second montior (and an AW3418DW as my primary).

Just got my RTX 2080 yesterday, I am also having the same issue, I have the S2417DG monitor.   I have a dual monitor setup the other one is a regular 60hz monitor.  The flickering stops if I only use one monitor, or if I put my dell monitor to 1080p resolution.  I suspect this is not a hardware issue and most likely a driver issue. some people were able to resolve this issue by creating a customer resolution in NVIDIA Control Panel -> Display -> Change Resolution -> Customize -> Create Custom Resolution -> Timing, and change the 'Standard' setting to something other than 'Automatic' -> 'CVT Reduced Blank'.  However I did not have success with doing this.  Other solutions were to switch from a DP cable to a HDMI cable or use a third party program called Nvidia inspector.  But none of this worked for me.  There will be a new driver release next week I hope that fixes it.
