Overview
Roku's 3840R is a black streaming player that connects over Bluetooth and Wi-Fi and outputs up to 1080p Full HD.
Unlike the mounts and TVs elsewhere in this batch, the 3840R is a standalone streaming box meant to add Roku's app platform to an existing television rather than replace one. Its output tops out at 1080p, built for standard high definition streaming rather than 4K playback. Bluetooth pairing covers headphones or a Roku remote, while Wi-Fi handles the internet connection needed to stream. Recent purchase volume, around 10,000 units in the past month, points to steady ongoing demand.
- Brand: Roku
- 1080p Full HD output
Who it's for
Anyone with a non-smart or older TV who wants Roku's app ecosystem without buying a new television. Someone dead set on 4K or Dolby Vision output should look elsewhere.
Pros and cons
- Adds Roku's app platform to any HDMI TV
- Bluetooth pairing for headphones or remote
- High recent purchase volume suggests steady demand
- Capped at 1080p, no 4K output
- No wired ethernet option listed
Performance notes
Streaming quality on the 3840R is capped at 1080p Full HD, so it suits standard HD content and apps rather than 4K libraries. Bluetooth support means it can pair directly with headphones or a compatible remote instead of relying on line of sight infrared, and Wi-Fi is the only listed connection method, so a strong home network matters since no wired option is given.
