The Roku Streaming Stick Plus 4K is a compact HDMI streaming stick that adds a full smart TV interface, 4K playback and HDR support to almost any television with a spare HDMI port. It is aimed at people who want a clean, simple setup without a big box on the TV stand, and it's small enough to live permanently behind the screen once installed.
In terms of output, it supports 4K UHD at up to 60 fps, with HDR10 and HDR10+ for compatible TVs, so it can take advantage of high-contrast content on Netflix, Disney+, Prime Video and similar services. Audio is sent over HDMI with support for formats like Dolby Digital and DTS pass-through, which is enough for most soundbars and AV receivers even though it does not handle Dolby Vision or Atmos like some more expensive streamers.
Inside, it runs on Roku's own platform with a quad-core processor and dual-band 802.11ac (Wi-Fi 5), which is plenty for typical fibre or cable broadband speeds and stable 4K streaming if your router is reasonably close. Power usually comes via the TV's USB port, but a mains adaptor is included if the USB output is too weak, which can help avoid random restarts on older sets.
The included remote is RF/BT rather than infrared only, so it does not need direct line of sight and can control TV power and volume as well as the stick itself. There are a few dedicated app buttons and a microphone for voice search, which is convenient for jumping straight to a show or app without digging through menus.
Day to day, the main appeal is that it is quick to set up, responsive in use and largely gets out of the way so you just pick a service and watch. If you are not chasing premium formats like Dolby Vision or Wi-Fi 6 and simply want a reliable 4K HDR streamer that does the basics well in a tidy package, the Streaming Stick Plus 4K is a sensible, low-drama option.
