Overview

Roku's 3840R is a black streaming player that connects over Bluetooth and Wi-Fi and outputs up to 1080p Full HD. It carries a 4.7 star rating from over 20,000 buyers, with about 10,000 units bought in the past month.

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.

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.

Strengths and trade-offs

Drawn from this product's published specifications.

What to check first

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.
