What is HDCP error and how can I solve it?


HDCP stands for High-Bandwidth Digital Content Protection, a copy protection scheme to eliminate the possibility of intercepting digital data midstream between the source to the display.

The format is designed by Intel and licensed by Digital Content Protection, LLC using an authentication and key exchange procedure before video and audio is presented.

During authentication, if there is incompatibility between the source (Home Theater System/DVD player/Set top box etc) and sink (TV display) device, it is often displays on-screen as a snowy image/green image or an error message. These errors are known as 'HDCP error'.

Following are some suggestions to eliminate the HDCP error:

  • Try a different HDMI cable
    • Ensure the HDMI cable meets the specification
  • Check the TV display
    • Ensure the TV meets the specification
  • Use alternative HDMI input
    • It could be the HDMI input is faulty, try using other HDMI input
  • Firmware check
    • Ensure that your HTS / DVD Player and TV is having the latest firmware. Please refer to the respective support website for the latest firmware
