Hi all, I have had a Samsung U28E850 for a few years now and it has been working great until a few months ago.

Recently however I have been having an issue in which the screen will blink from normal to black (for approx 3/4 seconds) and back to normal again every 20/30 minutes. I suspect it may be something to do with the refresh rate on the screen, as now in "Advanced display settings" it is being displayed as 59Hz rather than 60Hz. No matter what I do I have been unable to change this refresh rate to 60Hz despite it being an option. When i click "apply" on 60Hz, nothing happens and the Information tab still displays the refresh rate at 59Hz.

It is a 3840x2160 60hz screen and I am running it through a display port. I have a NVIDIA 1080Ti and am on Windows 10. I have tried an alternative DP cable and the problem has persisted. I have ensured that all drivers are up to date.

Any suggestions would be greatly appreciated.

Make sure you're on the latest BIOS update for your motherboard. Use DDU to uninstall your GPU drivers and reinstall the latest drivers you find off of Nvidia's support site.
