Overview
A bedroom or kitchen television gets streaming from this small Roku box, which connects over HDMI, comes with a remote and lists a short set of popular services.
Roku makes this model simple, with an easy setup claim and a compact body that is easy to tuck away. The resolution is limited, and the listing names no ports beyond HDMI or any power details.
Who it's for
Secondary rooms, dorm sets and older HDMI televisions suit this player, where a modest resolution is enough. Owners of large or newer screens should look at a model with higher output.
Pros and cons
- Remote control included
- Wide codec support
- Output limited to 720p
- Power and extra ports not described
- Short named service list
Performance notes
Picture quality tops out at the listed resolution, so a larger screen looks softer than on a higher output player. Codec support for the newer HEVC format allows efficient streams, while network speed decides whether playback is smooth. The memory figure affects app storage rather than picture quality.
