Overview
Roku's 3810R streaming player outputs 4K UHD over a Wi-Fi connection and runs the Roku smart platform.
This model steps up from Full HD Roku players to 4K UHD, aimed at televisions that can display the extra resolution. Some fields in the listing data, including color and weight, come through as placeholders rather than real values, so those details are left out here rather than guessed at. Recent purchase volume of about 4,000 a month is well above the 1080p Roku listing in this same batch.
- 4K UHD resolution
- Roku smart platform
- Wi-Fi connectivity
Who it's for
Fits owners of a 4K television who want Roku's interface and app catalog without buying a new smart TV. Less useful for anyone whose TV only supports 1080p, since the extra resolution goes unused.
Pros and cons
- 4K UHD output
- Strong recent purchase volume
- Color and weight not clearly listed
- No wired ethernet option given
Performance notes
Video streams over Wi-Fi and is decoded up to 4K UHD, so picture quality on a compatible television scales with source content and network speed. The Roku platform handles app navigation and search across connected streaming services.
