High-bandwidth Digital Content Protection (HDCP) is a security feature developed by Intel Corporation that requires the use of HDCP-certified products in order to receive a HDCP-encrypted digital signal. Often times these errors occur between televisions that are powered off periodically and cable boxes and game stations that stay on 24 hours a day without going into standby. The easiest way to re-negotiate the HDCP handshake is to power cycle the source device and the display, then power on the display, and then the source device.
Here are some other things to try:
- Ensure that your HDMI cable is securely positioned in the ports with no sharp bends that could cause a poor connection. Any splitters and extenders should also be tightly connected and secure.
- Check the actual connector end for any damage to the pins. Switch out the HDMI cable to see if the error still exists.
- Try setting the television back to factory defaults by using the Menu options. Once the default settings are
restored, check to see if the HDCP handshake issue has been resolved.
- Always be sure to check your television brand manufacturer website for the latest firmware update for your model.
