4K Monitor randomly goes black and comes back on

[JaspervanV]

I have a very annoying issue with my new Surface Pro connected through dock with 4K external monitor. Have been breaking my head about but don't have any ideas left..



Microsoft Surface Pro - i7 - 8 GB - 256 GB

MICROSOFT Surface Dock

AOC Q2577PWQ (2560 x 1440 60 Hertz)

Club 3D Mini DisplayPort to Displayport Cable


Microsoft Surface Pro 4 - i5 - 4 GB - 128 GB

MICROSOFT Surface Dock

Samsung LU28H750UQUXEN (3840 x 2160 / 60 Hertz)

Club 3D Mini DisplayPort to Displayport Cable


These 3 configurations work without any problems.

In this configuration the external monitor blacks out for a couple of seconds randomly a couple of times per hour. Showing on screen [Displayport] indicating it doesn’t get signal.




So excluded is defect on monitors, cable or dock since the all work fine combined with my (old) Microsoft Surface Pro 4 - i5 - 4 GB - 128 GB leaving the Microsoft Surface Pro - i7 - 8 GB - 256 GB as the source for the issue. I did all the updates (for Surface itself and Windows). Deleted the display firmware and reinstalled. All without effect.


Don’t know what to do about it anymore. Please help!

I got a Surface Pro 2017 i7 16Gb 512Gb, hooked to a Samsung U28D590 4K, and have had the same issue with 2 equal machines, prior I had the same monitor used on a Surface Pro 3 i7 8Gb 512Gb, same mDP-DP cable, and worked with no issue 4K@48Hz to 4K@52Hz, so here are my results while trying to fix this.

I found the issue, is more incident when using video, Chrome is worst, and using image Apps like Adobe After Effects it's almost unusable, but even with Visual Studio just scrolling causes the black blink issue. Always tested with 4K@60Hz, using 4K@30Hz reduces frequency but doesn't solve.

- Surface Pro 2017, cable mDP-DP, several Intel drivers, including MS default: got issue.
- Surface Pro 2017, Dock cable mDP-DP, several Intel drivers, including MS default: got issue.
- Surface Pro 2017, cable mDP-DP, Intel drivers v22.20.16.4815 : no issue, but got image freezes and continuous display recover System events.
- Surface Pro 2017, cable mDP-DP, Intel drivers v21.20.16.4678 : no issue.
- Surface Pro 2017, cable mDP-DP -> 4K, and Dock mDP-DP second 4K, Intel drivers v22.20.16.4771 : no issue.

So Guilherme do I read correctly that Intel drivers v22.20.16.4771 fixed the problem for you? If yes; where did you find this driver? Can't find it in Intel download center

Sorry I wasn't clear, but the Intel drivers v22.20.16.4771, don't give the issue only with that particular setup, having 2 x 4K screens connected, one to the Surface and the other to the SurfaceDock. For single 4K monitor, drivers v21.20.16.4678, work without any issue, both connected to Surface or throught the Dock.

Intel Display drivers v21.20.16.4678:

My Surface Pro 3 / Club 3D combo was an intermittent problem until I did these things:

1. Removed, then allowed to auto-install the Intel graphics drivers.
2. Made sure these where the latest from Windows Update.
3. Updated the firmware in my Club 3D (SUPER IMPORTANT)
4. Kept the Club 3D cool. On particularly hot days, my Club 3D will overheat and cause the screen to blank out until it has cooled off. If it feels hot to the touch, you may be having this issue.
