Yes they will because all the cable companies are making the change to HDCP 2.2 if You got cable.

Samsung support told me only one wireless outfit offers HDCP 2.2

I forgot which one He said?

Also, the cable company in Your area may have already upgraded to this new anti-piracy HDCP 2.2 already.

That would be why You don't have the problem with the ROKU-4 like I do.
