This issue occurs randomly and lasts only 1-2 seconds, then the display returns to normal. The frequency of occurrence can range from once every 10-15 minutes (sometimes longer), or as often as once every couple seconds (though this is a rare condition). Sometimes the issue frequency increases when additional applications are opened on a display, but it has also occurred with no applications open. All docking station functions (keyboard, mouse, Ethernet, display) appear to act normally most of the time. I have searched through many forums and posts relating to this topic and tried a number of troubleshooting procedures (listed below), but nothing seems to rectify the situation. The problem only started happening recently after my computer (Windows 10 OS) crashed and had to be rebuilt from bare metal (the SSD had become warped). I had been operating in the exact same HW configuration (other than the new SSD) before the crash for over a year without seeing this issue. My system configuration and specs are listed below. I have posted the DisplayLink Support log file as well. I have this computer connected via USB 3.0 port to a StarTech.com docking station (USB3SDOCKDD). The docking station is connected to a KVMP switch via USB and dual DVI-D connectors. Dual Dell monitors are connected to the KVMP switch, and these are the displays that black out. I have seen both black out individually, but not at the same time. The native monitor on my laptop does not black out. I also have a Windows 7 OS Dell laptop connected to the KVMP switch, and there are no blackouts of the displays when that system is sending data through the switch. This leads me to believe that the monitors and the switch themselves are fine, and the problem resides with the Windows 10 laptop, the USB docking station, or the interaction between the two.
Troubleshooting Steps:
1. Swapped DVI-D cables from the Windows 7 laptop side of the KVMP switch to the Windows 10 laptop side of the switch. Swapped DVI-D cables between the two monitors.
2. Tried multiple USB 3.0 ports on the laptop.
3. Uninstalled/Reinstalled/Updated the following drivers
a. DisplayLink USB (tried drivers 8.3, 8.4 and 8.5 beta – original driver that came with the device was 7.6 which worked fine with Windows 10 for over a year)
b. NVIDIA GeForce GTX 980M GPU (uninstalled with DDU)
c. ATEN KVMP switch
d. Dell Monitors (tried with Dell driver and Generic PnP Monitor driver)
e. Intel(R) USB 3.0 eXtensible Host Controller – 1.0 (Microsoft) – Uninstalled through Device Manager
f. Used Driver Easy to check for any additional driver updates
- Applied all available updates (except USB Root Hub xHCI: Downloaded the update files {amdxhcireg Security Catalog and Setup Information} nothing appears to happen when I right-click on the setup file and select install and the device still shows that it needs updating in the Driver Easy menu)
4. Unselected “Allow the computer to turn off this device to save power” for each of the USBC peripherals (Device Manager >> USBC >> {USB device} >> Properties >> Power Mangement)
5. Modified Advanced display settings for multiple displays; changing which monitor was “main” vs. “Extend desktop to this display”
6. Modified GPU clocking using NVIDIA Inspector
