HD streaming stick for TV upgrade

The Roku 3840R is a compact media streamer that plugs directly into an HDMI port and draws power from the TV USB-C connection. It delivers up to 1080p video with up-scaling from 720p and supports digital stereo plus DTS Digital Surround pass-through over HDMI. Dual-band 802.11b/g/n Wi-Fi at 2.4 and 5 GHz handles network connectivity.

Buyers wanting simple HD streaming.

This stick suits viewers who want free live channels, major apps and voice search on an HD television without extra cables or a wall outlet. The included voice remote controls TV power, volume and mute alongside the Roku interface. Households requiring 4K resolution, HDR formats or Ethernet connectivity should consider a different device.

1080p output with USB-C power from TV

The single specification that decides fit is the maximum video output of 1920 x 1080 at up to 1080p with up-scaling from 720p, combined with a 5 V 1 A USB-C power draw that many TV USB ports can supply. If the display or projector accepts only higher resolutions or demands more power than the TV port provides, this model will not meet the requirement.

Questions about this item

Does my TV need a specific HDMI port to fit the 21 mm wide player?

The player measures 21 mm wide and 11.5 mm high, so it fits a standard HDMI port without blocking the neighbouring one.

Will the 802.11b/g/n dual-band Wi-Fi (2.4 GHz / 5 GHz) connect to my older router?

Yes, the stick supports 802.11b/g/n on both 2.4 GHz and 5 GHz bands, matching most routers still in use.

How do I confirm the stick is streaming at 1080p after setup?

Open Settings > Display type on the Roku home screen; it will show 1080p when the TV reports that resolution.
