Hi James,
thank you for your advice.
At first I had with the CCCP player the same problem as with Mirillis Splash: The playback area got black when I moved it onto the tv.
But I could solve the issue by disabling the notebook display and defining the tv as primary display. With this configuration both CCCP and Splash work with the DisplayLink video adapter.
No I have the problem that my notebook fan gets quite loud due to the decoding work, but this is another problem.
Best regards
Bernhard
