If you experience the error code C7353 on your Google Chromebook, it's typically caused by an unsupported monitor or screen. Google only supports playback on internal monitors or through HDCP (High-bandwidth Digital Content Protection) compatible monitors. Follow the troubleshooting steps below to resolve the issue. Disconnect your display Disconnect your computer from your external monitor and try playing a movie or TV show again. If this resolves your issue, it's likely that your external monitor or TV does not support HDCP. What should I do next?
