How to use 50Hz mode
Your Chromecast is designed to pick the best mode supported by the TV and typically the TV will adjust the mode based on the stream. However, if you’re seeing jitter or stutter issues when viewing certain sports content that is encoded for 50Hz (typically in Europe and Asia), the following steps will force your TV into 50Hz mode and will likely correct the issue.
Note: This is an advanced option and may not be applicable for most users.
