Roku Ultra — 4K Streaming Player
The fastest Roku experience with cinematic 4K HDR, Dolby Atmos sound, Wi-Fi 6 and the rechargeable Voice Remote Pro (2nd Gen)
Designed for demanding living rooms and dedicated media systems, the Roku Ultra pairs class-leading streaming performance with broad platform compatibility and pro-grade I/O. 30% faster than prior Roku players, it launches apps instantly, renders 4K HDR sources faithfully (HDR10+, Dolby Vision), and delivers immersive object-based audio via Dolby Atmos. Robust connectivity — Wi-Fi 6, Ethernet and HDMI 2.1b — ensures high-bandwidth delivery for today’s highest quality streams.
Speed, Quality, and Control — Optimized
Roku Ultra targets fast, reliable playback and uncompromised picture and sound fidelity. A tuned platform accelerates app launches and UI responsiveness (≈30% faster than legacy players), while modern connectivity and codecs support HDR10+, Dolby Vision and Dolby Atmos for cinematic visuals and immersive audio. The bundled Voice Remote Pro (2nd Gen) elevates control with hands-free voice, backlit keys, lost-remote locate and USB-C charging for professional convenience.
Performance figures and feature availability are manufacturer-specified. Some apps, features and formats require subscription or device compatibility.
Core Capabilities
Accelerated Platform Performance
System-level optimization and a modern processor deliver approximately 30% faster app launches and navigation versus previous-generation Roku devices. The result is immediate responsiveness during content discovery and playback.
Cinematic Picture — HDR10+, Dolby Vision

Immersive Audio & Flexible Pass-through
Dolby Atmos support and broad codec compatibility (DTS, Dolby Digital) make Roku Ultra a flexible front-end for both native Atmos streams and AV receiver pass-through workflows.
