Been researching this for a whilst and found this forum link to stop HDCP protected content from displaying a black screen but hearing audio from streaming services such as Netflix and Disney.
Disabling Hardware Acceleration only works for me on Google Chrome but not Firefox.
Streamed video content is now displaying Google Chrome.
I can live with this for the moment.
Thanks so much
