What is HDCP?

High-bandwidth Digital Content Protection (HDCP) is a system designed to protect digital content. The technology is intended to protect unauthorized duplication of high definition (HD) video and audio as it travels across connections—from your computer to your TV or monitor, for example. Your setup, from devices to displays to cables, adapters, and software drivers, must all be HDCP compliant in order to watch HD-quality videos with HBO GO.

For example, if you are watching HBO GO on an HDCP-compliant laptop, you shouldn't encounter any issues. However, if you connect that same laptop to a TV, then your laptop, the TV, and the cable connecting the two devices must all be HDCP compliant in order for you to view HD-quality video in HBO GO.

How do I know if my setup is HDCP compliant?

HBO GO verifies that your setup is HDCP compliant when you play a video. If your setup is not HDCP compliant, HBO GO displays an error message and one of the following will occur:

  • Video will play in standard definition only.

  • If a standard definition video is not available, playback will be limited to either audio only or video only. In most cases, video won't play at all. 


In general, newer HDTVs and HDMI or DVI cables should be HDCP compliant. Older TVs, VGA cables, and some older DVI or HDMI cables are more likely to lack support for HDCP. If you aren't sure, try checking the manufacturer's specifications for the device, cable, or adapter.

What should I do if I'm getting an HDCP error?

If you've never had an issue when watching HBO GO with your setup before and get an HDCP error message, it's most likely that the HDCP authentication failed temporarily. In some cases, an out-of-date video driver or loose cable connection can cause your setup to appear as if it isn't HDCP compliant.
