Streaming Player for 4K HDR TVs

The Roku Ultra 2024 model 4850R is a digital media streamer designed for HD, 4K and 4K HDR televisions. It delivers up to 2160p at 60fps with upscaling from 720p and 1080p sources. The device supports Dolby Vision at 60fps, HDR10/10+ and HLG formats for cinematic picture quality. A premium High Speed HDMI cable is included in the box for immediate connection.

Voice Remote Included — Not for Legacy AV Setups

This unit suits viewers who want the Roku Voice Remote Pro (2nd edition) with backlit buttons, hands-free voice control and a rechargeable battery charged via USB-C. It also fits listeners who wish to pair Bluetooth headphones directly to the player for private listening. Buyers whose audio systems lack an HDMI input for Dolby Atmos pass-through or decode should look at something else.

HDR Format Support Decides Compatibility

The single specification that determines whether this is the right part is the television's HDR capability: the player outputs Dolby Vision at 60fps, HDR10/10+ and HLG. If the display does not support at least one of these formats, the player will still function but cannot deliver its highest picture quality.
