Last refreshed Aug 4, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A straightforward small-screen smart TV for a bedroom or kitchen where streaming apps matter more than picture punch. Its panel tops out at Full HD, so it is not the set for a bright living room or a movie fan chasing detail.

Overview
Unlike a plain display that needs a streaming stick plugged in, Roku Select Series sets carry the Roku platform inside, so apps, live channels and the home screen are built into the television itself. The panel is a direct-lit LED screen that runs at Full HD, and the set stands on its included feet or hangs from a wall bracket. A voice remote handles searching and playback, while Wi-Fi and Bluetooth link the TV to your network and headphones.
What earns this set a place is the software: the Roku home screen puts free channels, live news and major apps a click or two from power-on, and automatic updates keep that list current. The picture hardware is modest by design, with a Full HD panel and a low refresh rate, so fast sport and dark scenes will not look as sharp as they do on a pricier set. Buy it for convenience and screen size, not for image quality.
Who it's for
Someone furnishing a second room wants a television that arrives with the streaming platform already aboard and a remote that takes voice commands. The size and panel suit close viewing, so it works on a dresser or counter rather than across a large room. Shoppers chasing the deepest blacks or the smoothest motion should look at a different class of set.
Pros and cons
- Roku platform built in, no streaming stick needed
- Voice remote searches across thousands of apps
- Three HDMI inputs for console, cable box, player
- Bluetooth Headphone Mode for quiet listening
- Full HD panel, not 4K
- Refresh rate listed at 60 hertz only
- HDR format not listed
- Batteries for the remote not included
Performance notes
Picture results come from a direct-lit LED panel running at Full HD, so sharpness holds up at close range but fine detail falls away on a large wall. Roku Smart Picture reads the incoming signal and selects a picture mode on its own, which trims setup work but leaves less room for manual tuning. Audio relies on the built-in speakers tuned for speech clarity, and Bluetooth Headphone Mode routes sound to wireless headphones when the room needs quiet.

Frequently asked questions
What comes in the box with the Roku 40R3D5?
The box holds the television, a power cable, the voice remote, the stand and a user manual. The remote needs two AAA batteries, which are not included, and no HDMI cable or wall bracket ships with the set.
Can I mount the Roku 40R3D5 on a wall?
Yes. The set supports wall mounting and uses a 200 x 300 mm VESA pattern, so you need a bracket with that hole spacing. The stand is included for tabletop use, but the mounting hardware itself is not part of the box.
Does the Roku 40R3D5 need a streaming stick?
No. The Roku platform is built into the television, so apps, the home screen and free live channels run on the set itself. You only need Wi-Fi and your own streaming accounts.
Can I watch the Roku 40R3D5 with wireless headphones?
Bluetooth Headphone Mode sends the audio to compatible wireless headphones so the rest of the room stays quiet. The built-in speakers handle normal viewing, and the set also outputs sound over HDMI, optical or Bluetooth.
What can I connect to the Roku 40R3D5?
Three HDMI ports cover a game console, a cable box and a media player, with one USB port and an optical connection alongside them. Wireless links include Wi-Fi and Bluetooth, and the set pairs with gaming consoles, laptops, phones and speakers.
