Thanks for joining our community with your question. I’d be happy to help you answer it.
Looping content from the USB port on your new NS-43D420NA18 is not an option. Any of our models using the ROKU SMART platform would have this capability though. I apologized if you were led to believe this model had that capability. Please let us know if you have any other questions.
