Thank you for contacting us, X1 remote control does not support PC. X1 remote supports infrared devices and Bluetooth devices, as well as ROKU stick+, Sonos speaker, Philips hue (other wifi devices are not supported). The X1 remote control will be on the shelves early next year, and the specific date is uncertain.

Would you please tell the Samsung Specific Model of your device? thanks :) such as: Brand:LG Model: 60UF7300 Because the remote control of each device is different, knowing the specific model of your device, we can better test and solve the problem. If the database is not complete, we can update it for better use. We can even add your Specific Model to our database so that you can one-click to add. I took a video for you, hope it can help you better know U1. "https://www.youtube.com/watch?v=6tRiVf28G74 "
