hi,
i have the same problem after the Windows 10 Anniversary update, the monitor is still black, mouse and keyboard are working. Before the update all works fine.
I tried also, the 8.0M2 driver, but no effect.
Hardware ID from my HP device: USB\VID_17E9&PID_01D4
In attach you can find the log file, created by DisplayLink Windows Support Tool.
thanks in advance,
br
