No, you do not need a Roku for every TV in the house. In fact, Roku has designed all its streaming devices to be compatible with any TV that has an HDMI connection. This means any Roku streaming player can be connected to a high definition or even 4K TV. However, to stream TV shows and movies in HDR or 4K, you’ll need an HDMI-compatible Roku streaming player, and a TV that supports these higher resolutions. This is great news since it means you can experience streaming content on any TV in your home without having to buy multiple Roku devices. Here are some key points to keep in mind:
All Roku streaming players have HDMI connections and can be connected to any television with the same connection.
To take full advantage of HDR and 4K streaming quality, your television must also support these resolutions.
You can enjoy streaming content across all your TVs without needing to buy multiple Roku devices!
So, no matter how many televisions you have, with Roku, you only need one streaming device. Just plug it into your TV, set it up, and start enjoying unlimited streaming options.
