If you have a Roku device, you may be wondering what happens if you unlink it. This is a question that many people are asking because Roku devices can be used as standalone streaming devices or as part of a connected TV system. The answer to this question is that Roku devices can still be used, but they will not work as well. If you want to watch your favorite streaming content on your Roku device, you will need to use an app like Netflix or Hulu Plus.
