My Amazon FireTV is hardwired to my AT&T 5268AC router via an 8-port ethernet switch and into the game port of a Pioneer 824 A/V receiver and then to my Samsung TV. My FireTV tells me I cannot display the 4K picture because some component of the system is not HDCP2.2 compatible.
I lack expertise in this area, but I sure could use some help in finding which component of the setup is not HDCP2.2 compatible. Any help you can provide would be appreciated. Thanks in advance.
