Hi @morunok3,
Welcome to the Roku Community!
We understand that you want to use Nintendo Switch on your Roku device that is connected to your Samsung TV. We would be more than willing to provide you with further details about this.
I just wanted to inform you that the Nintendo Switch is not compatible with a Roku device. The Nintendo Switch is an external gaming console that requires a direct connection to a television and does not have the capability to connect to other external devices like Roku streaming devices. It is specifically designed to work with Roku TVs only.
In order to play games on your Nintendo Switch, you will need to utilize the input selection feature on your Samsung TV remote to switch between the Roku device and the Nintendo Switch.
We hope you find this information helpful. Thank you for your understanding.
Regards,
Riamie
