Overview
The Roku 3920RW-SW is a 4K UHD streaming player that connects over HDMI, weighing 0.62 pounds in a purple finish. It sits above 1080p Roku sticks in the lineup by supporting 4K output for compatible TVs.
Unlike Roku's 1080p stick models, this one is built for 4K TVs and will pass through 4K content rather than capping at Full HD. The purple color and light weight suggest a compact stick or box form factor, though the specific product shape isn't detailed beyond the HDMI connection and weight.
- 4K UHD resolution
- HDMI connectivity
- Purple finish
- 0.62 lb
Who it's for
Suited to owners of 4K TVs who want Roku's app catalog at native 4K resolution rather than 1080p. Not necessary for anyone with an older 1080p-only TV, where a cheaper Roku model would use the resolution just as fully.
Pros and cons
- 4K UHD output for compatible TVs
- Light at 0.62 lb
- HDMI only, no listed ethernet option
Performance notes
4K UHD output means content streamed through this player can reach full 4K resolution on a compatible TV, unlike Roku's 1080p stick models. It connects exclusively over HDMI, with no separate ethernet port mentioned, so streaming quality on Wi-Fi networks will depend on signal strength.
