Overview
The Roku 3400R streaming player pushes output up to 4K UHD and connects to a TV over a wireless network, adding Roku's channel platform to a set that doesn't already have smart apps built in.
Because the only connectivity listed is wireless, setup depends on a solid Wi-Fi signal reaching the TV rather than a wired backup. The core appeal is straightforward: 4K UHD output paired with Roku's platform on a TV that otherwise lacks streaming smarts.
- 4K UHD output resolution
- Wireless network connectivity
- Roku streaming platform built in
Who it's for
Fits owners of an older or basic TV who want 4K streaming apps without replacing the whole set. Less useful for anyone who already owns a smart TV or streaming device with 4K apps built in.
