I have a new Vizio 4K TV that I purchased a few months back. I originally had a streaming stick which worked okay but I wanted to get a player that supported 4K. I bought the streaming stick 4K+ which seemed to work fine but the remote had problems pairing to the TV. So I upgraded to the Ultra and within days I started getting that dreaded HDCP error code popping up about every 3 days. I did the restart process - unplugging the HDMI cable from the TV and Roku player, then unplug both the TV and player, then reconnect TV and player and power on TV and player. I changed out the HDMI cable to one that supports 4K 2.2 and still got the error. I disabled the auto-adjust refresh rate and I’ve also done the system restart option. I still get the error about every 3 days. Since I’ve tried all of the suggested fixes for this, I’ve come to the conclusion that it’s an issue with the player since the error goes away temporarily but reappears constantly. I have since switched to Amazon Fire Cube - good luck to anyone still struggling with this HDCP headache!
We do apologize for the inconvenience this has caused you.
If you're still experiencing an HDCP issue on your Roku device, please reply here with the serial number of the player. It can be found by navigating to Settings > System > About. I'll be able to further assist you from there.
