Overview
A cord cutter who wants one remote for live channels and apps gets a 4K screen with Roku built in. The set tunes over-the-air broadcasts through its ATSC tuner, and the Roku platform pulls streaming channels over Wi-Fi. A VESA pattern lets it hang on a wall bracket, or the included stand sets it on a dresser.
Roku TV turns the set into a streaming hub without a separate box, and the fast refresh rate holds sports and action together. The direct-lit backlight cannot dim zones independently, so dark scenes lose depth, and the glossy finish mirrors lamps and windows. Viewers who mostly watch at night or in a dim room get the most from it.
Who it's for
A bedroom, dorm or guest room where the TV doubles as the streaming device suits this set, since Roku covers apps and the tuner covers antenna channels. A dedicated home theater chasing deep blacks and uniform lighting should look elsewhere.
Pros and cons
- Roku TV built in, no streaming box needed
- 120Hz panel handles fast motion
- HDR10 support for compatible content
- Three HDMI inputs for consoles and players
- Glossy screen reflects room light
- Direct-lit backlight, no local dimming
- Stand width not listed
- No Bluetooth audio output listed
Performance notes
A direct-lit LED panel lights the whole screen from behind, so bright objects bleed into dark areas instead of dimming in zones. The fast refresh rate redraws motion more often, which smooths panning shots and sports. HDR10 feeds a wider brightness range to compatible sources, though the panel's contrast sets the ceiling. Streaming speed depends on the Wi-Fi signal in the room.
