Welcome, and thank you for posting here at the Roku Community, @arvb!
We appreciate you reaching out to us regarding this matter. No worries! We'd be more than happy to further assist you with this.
Be advised that changing the selected system language also affects the audio and captioning languages. Use the steps below to help you change to your preferred system language on your ONN Roku TV:
- Navigate to your Home screen
- Scroll up or down to select Settings
- Select System > Language
- Select your preferred language
You can also change your preferred caption or audio language separately. Refer to our Support article on How to change the preferred language on your Roku® streaming device for further details and clarification.
