Screen flicker

[Wim]

When the screen blacks out, does the device drop off the USB bus (eg does it disappear from device manager) or is it just the screen that blanks?

Does it improve if you connect your USB 3.0 hub with a USB 2.0 cable, to see if it is a USB 3.0 problem?

Thank you for your answer.
I finally managed to circumvent the old proprietary Samsung GPU drivers for the current AMD version. Sadly the behavior of the adapter has not changed much.

USB 2.0: Stable, but incredibly laggy. Even watching 480p is pretty bad.

USB 3.0 (Laptop port): Exactly the same, very stable. Fullscreen 1080p video playback without a problem. This is not an option for me, because I only have 2 USB 3.0 Ports, which are both in constant use.

USB 3.0 (via Exsys ex-1188hms 7 Port Hub): Screen blacks out in random intervals. Hub firmware and USB 3.0 controller drivers are up to date, no other device has encountered any problems.

3D-Applications still crash with all of the above configurations, the following passage is an exemplary crash report. This did not happen with the old Dynadock and 6.x drivers.

EDIT: The adapter remains in the device manager, but the manager itself seems to search for new hardware everytime the blacks out.
