HDCP limitation on HDMI output of MacBook Pro

[Mikolaj]

I'm trying to connect my MacBook Pro M1 Max to a conference room screen with HDMI, but I only see a message "HDCP content“ on that external screen. But I'm not trying to share Netflix or any other HDCP protected content, just my Desktop and eventually some Keynote presentation. The same result with mirroring of the internal screen and in the extension mode.

I assume that the screen in the room does not support HDCP, but the question is if the entire output from MacBook is secured by default even for non-protected content like an empty desktop? If so, is there any workaround?

My Windows laptop works fine in the same conference room.

Thank you for your advice!

Try doing it using a DisplayPort to HDMI adapter instead of the HDMI port on the computer.
