Roku has finally made its refreshed media streaming box official. In addition to 4K video playback capabilities, the new set-top box packs a few neat surprises such as a remote locator.

The Roku 4 is powered by a speedier quad-core processor assisted by 1.5GB of RAM, up from just 512MB in the Roku 3. This allows the box to play back 4K streams at up to 60 frames per second. Buyers also get 802.11ac MIMO Wi-Fi, optical audio out, an Ethernet jack, HDMI port, microSD card slot and Wi-Fi Direct-enabled remote with voice search, headphone jack and the aforementioned remote finder function.

To use the function, simply press the button on top of the box which will cause the remote to emit a tone. This of course could be immensely helpful if you're constantly losing your remote between the couch cushions or behind the bed.

The box itself is significantly larger than the Roku 3 so it'll take up a bit more room on your home entertainment center or behind your television. Roku has also reworked the UI and upgraded it to 1080p quality. It's also now easier to find content as the universal search function has been expanded to include TV shows, actors and directors.

The Roku 4 is available for pre-order starting today. It's priced at $129.99 - up from the $99.99 price point of the Roku 3 - and will ship on October 21.
