Overview
Not a 4K player, the Express is a Roku box that streams full high definition video over Wi-Fi through the Roku platform and ships in black.
Roku limits the Express to the basics, which suits a television that has no built-in apps. Hardware details are thin in the listing, with no ports, remote or services named, and the weight looks like a boxed shipping figure.
Who it's for
Households with a full high definition television and a Wi-Fi network who want a simple streaming source suit this player. Owners of a 4K display should consider a higher-resolution Roku model.
Pros and cons
- Roku smart platform
- Full high definition output
- Resolution tops out below 4K
- Ports and remote not described
- Weight entry may be shipping weight
Performance notes
Stream quality depends on the Wi-Fi link and the app, since the player decodes and passes video to the television. Full high definition needs less bandwidth than 4K, so weaker networks cope better. The listing names no codec or HDR support.
