Overview

The Roku 55R4A5R Select Series is a 55-inch 4K smart TV designed by Roku to pair sharp picture quality with its famously simple streaming platform. The 4K UHD panel renders content at four times the resolution of standard HD, and HDR10+ support dynamically adjusts brightness and color on a scene-by-scene basis for noticeably richer visuals. An automatic brightness sensor reads your room's ambient light and adapts the display accordingly, which means the picture looks balanced whether you're watching in a bright living room or a dimmed home theater.

On the software side, the Roku operating system provides a customizable home screen where you can pin your most-used streaming apps, HDMI inputs, and free live TV channels for quick access. The TV comes with access to over 400 free live channels plus major streaming platforms like Netflix, Hulu, and Disney+. The enhanced voice remote lets you search across apps by speaking, includes a headphone jack for private listening via Headphone Mode, and features a lost remote finder — a genuinely useful addition for households prone to misplacing remotes between couch cushions. Connectivity includes Wi-Fi, Ethernet, USB, and HDMI ports, and the bezel-less design keeps the TV's 48.5" x 31" footprint visually clean at just 10.2 inches deep. At 34 pounds, it's manageable for wall mounting or tabletop placement.
