When this error occurs, you will see the following message on your screen:
"Sorry, this isn’t working. Switching to Ultra High Definition (UHD) resolution requires High-bandwidth Digital Content Protection (HDCP), a protocol that protects against piracy. Please check that your TV Box is plugged in to an HDCP 2.2 compatible port. Since configurations vary, check your TV or receiver’s owner manual to confirm."
