Hi again,
I'm officially out of ideas.
I also tried buying DP->HDMI "active" adapter (whatever that means) as suggested by some sites and tried the shortest HDMI cable (0.5m).
Always the same behaviour of flickering.
At this point the only working solution is using the 2 DP ports of the station and the built-in HDMI port of the notebook. The USB->HDMI graphic adapter seems to work bad, after some point all the monitor goes black and all windows position are resetted to notebook monitor.
Any thoughts on this?
