While most Roku Streaming devices support 4K resolution, some streaming platforms are still catching up. Disney-owned Hulu recently updated its user-facing help pages to inform customers that the platform is finally offering 4K streaming and 5.1 surround sound audio on Roku devices. Previously, only 1080p streaming was available via the Hulu app on Roku. (The platform still does not support HDR streaming.)

Hulu has had a difficult time implementing 4K on its platform, announcing the capability in 2016 on select titles and devices before removing support entirely in 2018. It has since been re-added on some devices, such as the Apple TV 4K, but the move to add Roku to the list of 4K- and 5.1-compatible devices indicates the platform hasn’t given up on the lates resolution tech.

Streaming in 4K on Roku will not be offered for all of Hulu’s content, of course. Popular Hulu Originals like The Handmaid’s Tale and Catch-22 will be available in 4K, but it appears as though no third-party content is available yet for 4K streaming on Hulu via any streaming device, let alone Roku. In this regard, Hulu trails behind other services like Netflix and Amazon Prime.

Hulu’s addition of Roku to the list of supported platforms for 5.1 surround sound is great news for Hulu lovers who also own a 5.1 soundbar or other surround systems.

Roku devices are among the most popular streaming devices in the U.S. (as well as the world), making the 4K and 5.1 updates significant ones for Hulu viewers who want to be able to enjoy their favorite content in the best quality.
