Chromecast black screen on Z100 Pro

Hey again,

I tried to attach Chromecast to Zidoo Z1000 Pro, and it shows only a back screen.
If I attach through a hdmi extractor it plays properly.

I guess it relates to some content protection. Is it possible to bypass and make Chromecast working with Zidoo it without any hardware?

Thanks

 

Just an extra info:
When I restart Chromecast while watching the HDMI in, I see the boot animation for a few seconds, but after it freezes and never changes anything. When I close the HDMI-In and reopen, it's just black screen.

 

Ah just found it!

I needed to turn on HDCP 2.2 in settings!
And now it works like a charm.
