Dell XPS 9550, 9350 or Precision Mobile Workstation 5510 users may encounter flickering on systems with a Ultra-High Definition (UHD) 4k display when connected to a Thunderbolt dock (TB15) Type-C docking station with dual external monitors.
The flickering may be random and may continue after disconnecting from the TB15 dock until the system is restarted.
Dell Engineering and the graphics team have released an updated Intel video driver to resolve this issue. Please update to the Intel Graphics Driver 18.104.22.16890 or newer to resolve this problem.
You can download the latest graphics driver for your system from the Dell support website, Select your system model or enter your Service Tag, go to Drivers & Downloads, Video, then select the latest Intel HD Graphics driver.
