Overview
A shopper with a 4K television gets a purple Roku box that connects over HDMI, ships with a cable and remote, and adds screen mirroring and a headphone mode through the remote.
Roku includes the cable and remote, supports Miracast for phones and tablets, and updates itself, which makes setup simple. The service list is short and the resolution entries disagree, so the stated 4K needs verifying.
Who it's for
Households that want an HDMI cable, remote and mirroring in one box suit this player. Shoppers who must have verified 4K output should confirm with the seller first.
Pros and cons
- HDMI cable and remote included
- Automatic software updates
- Resolution entries conflict
- Only two services named
- Ethernet not listed
Performance notes
Picture quality depends on the network, the app and what the television accepts. HDR needs a display that supports it, and codec support for HEVC allows efficient streams. Mirroring from a phone relies on a stable local connection.
