Why is HDCP 2.2 important to playing 4K content?


HDCP is a copy and content protection standard. Copy protection/content protection has been around for a long time, and in its early stages was what prevented you from copying VHS tapes. The latest copy protection technology is called HDCP (High-bandwidth Digital Content Protection) and is used for digital devices like Blu-ray™ players, cable boxes and Roku® streaming devices. HDCP 2.2 is specifically for Ultra HD (4K) content.

If your 4K TV or audio/video receiver (AVR) does not support HDCP 2.2, you may see this message during setup:

Or you may see this message when trying to change to 4K UHD TV in Settings > Display type:

How do I solve this problem?

Here are the steps to verify that your other devices are capable of supporting 4K content:

  1. Your TV must be 4K UHD with an available HDCP 2.2 HDMI® input.
  2. Even if your TV supports 4K, not all inputs on that TV may be HDCP 2.2 enabled. Check the owner’s guide or TV manufacturer’s online support instructions to make sure your TV meets these requirements.
  3. If you are connecting your Roku player through an AVR, the AVR must also support HDCP 2.2. Every device in the chain between the Roku player and the TV must be HDCP 2.2 compliant. Check the documentation for your AVR to make sure that HDCP 2.2 is supported on the HDMI input that you are using. 
  4. If you are using an AVR and you want to see if it is the source of the issue, you should remove the AVR from the chain and connect your Roku player directly to a HDCP 2.2 input on your TV and see if you can stream 4K content when connected directly.

If you have a 4K TV, and your AVR does not support HDCP 2.2, you can still get both 4K video and use your AVR by connecting the Roku player directly to the HDCP 2.2 input on your TV, and using either ARC (Audio Return Channel) or S/PDIF to route the audio from the TV back to the AVR. 

What if I can’t change my TV or rewire my AVR?

You can still enjoy Full HD content. During setup, your Roku player will automatically select 720p or 1080p instead of 4K UHD. Or you can select 720p or 1080p from Settings > Display type.
