HDCP errors are simply the TV and the Roku not agreeing to handshake. That's actually the term used to describe what happens when two HDMI devices are connected. For some reason the data between the two devices isn't being conveyed satisfactorily. Sometimes it's because both devices are not using the same version of the HDCP protocol, but it's usually because there's a hardware issue. Either the cable has a fault, or one of the HDMI connectors has a problem. Power off both devices, disconnect the HDMI cable from both, and make sure there's no dust or other contaminant that might cause a problem. try using a different HDMI port in the TV. Try using a different cable. Try the Roku on a different TV.
If the Roku fails after all of these tests, then it has probably suffered a hardware failure. If it's still under warranty, Roku seems to be good at honoring it. If it's too old, save yourself a lot of time and grief and replace it.

If you have a 4K HDR television, try changing the display type to 4K at 30 Hz or 4K at 60 Hz. The 9.2.0 software upgrade seems to be causing problems with them. I've been told that they are working on the problem and will push another software update when it's done.
I have the Roku Ultra and the system updated on 10/29/19 and since then I have been getting this error, HDCP ERROR DETECTED. I've never had this problem before and I have not changed anything. The TV is a 60" LG UHD and I'm using a 2.2 4K HDMI. While the black screen with error code is displayed I can here the content audio playing. I have checked all connections and followed the Roku instructions but still not working. Please help!
