The Onn 40-inch Roku TV is Walmart’s no-frills 1080p smart TV for small rooms, and in 2026 it’s worth buying only at a clearance price. Some TVs need to fill a living room wall. Others just need to work in a kitchen, dorm, or kid’s bedroom without costing much. The Onn 40-inch Roku TV belongs firmly in the second group: Walmart sold it for about $98 to $128 during 2022 sales, which made it one of the cheapest name-brand smart TVs you could buy at that size. This Onn 40-inch TV review covers what you get for that money, what the 1080p screen does and doesn’t do, and what Walmart sells in its place now that Onn has moved away from Roku.
Quick verdict: The Onn 40-inch Roku TV is a no-frills 1080p screen with Roku’s easy interface, three High-Definition Multimedia Interface (HDMI) ports, and a light, compact body. It has no high dynamic range (HDR), no Ethernet port, no Bluetooth, and tinny speakers. It’s a fine second TV at a very low price, but newer 40 to 43-inch models give you more for similar money.

Where does the Onn 40-inch Roku TV stand in 2026?
Onn is Walmart’s house brand for TVs, streaming devices, and accessories. Contract manufacturers build the TVs, and Walmart sells them in stores and online. Walmart sold several versions of this 40-inch Roku TV over the years, including model 100097810 and the later 100058007, with nearly identical specs.
The bigger change came after Walmart bought Vizio. In November 2025, Walmart began selling Onn TVs powered by Vizio’s operating system (Vizio OS), starting with a 43-inch 1080p model listed at $89 for Black Friday, which The Desk reported as the apparent replacement for the Roku-powered Onn TVs. Walmart also sells a 43-inch Onn 4K Vizio OS TV (43S4V1) with Dolby Vision and HDR10+ for about $148, and in mid-2026 it added Onn Google TV models with quantum dot light-emitting diode (QLED) panels, starting at 55 inches.
So the Roku version is now leftover, open-box, or used stock. You can check what’s in stock at walmart.com. If you want a bigger Onn screen, our Onn 50-inch TV review covers the 4K Roku model.
Design and setup
The 40-inch Onn uses a charcoal-black plastic cabinet with gray bezels and two glossy feet. At under 12 pounds, it’s easy for one person to carry and set up. Attaching the feet takes a few minutes with a Phillips screwdriver; each foot is shaped for one side, so check the labels before you start.
The feet sit close to the edges, almost 35 inches apart, so your dresser or stand must be at least that wide. Owners describe the feet as lightweight, so a wall mount is the steadier option. The back has standard Video Electronics Standards Association (VESA) mounting holes; confirm the pattern in the manual before you buy a bracket, such as a small TV wall mount from Amazon.
Ports and connectivity
Three HDMI ports are generous for a TV this cheap. You can connect a cable box, a game console, and a soundbar, with the soundbar on the ARC port. A single USB port plays photos, music, and videos from a flash drive, though some file formats, such as Audio Video Interleave (AVI), may not play.
The TV connects to the internet over Wi-Fi only, since it has no Ethernet jack. That’s fine for most homes, but a weak signal in a back bedroom can cause buffering. It also lacks Bluetooth, so use Private Listening in the free Roku mobile app if you want to listen through wireless headphones.
Roku smart features and the remote
Roku makes this TV easy to live with. The home screen groups streaming apps, cable inputs, and an antenna tuner in one simple grid, and The Roku Channel adds free movies and live TV. The interface works with Amazon Alexa and Google Assistant speakers, and the Roku mobile app doubles as a remote with a keyboard for search. Our smart TV vs. Roku TV guide explains how Roku compares with Google TV and Fire TV.
The included remote is basic and has no voice button. Its volume and mute buttons sit on the side, where it’s easy to press them by accident. If you prefer a universal remote, look up Onn codes in your remote’s code list. Another easy fix is a Roku voice remote from Amazon, which works with Roku TVs and adds voice search.
Picture quality
No major testing lab reviewed this model, so the specs and owner reports provide the best picture of its performance.
Resolution and sharpness
At 40 inches, 1080p still looks sharp from a normal viewing distance of 5 to 6 feet. You won’t see much difference from 4K at this size in a small room, which makes a 1080p TV a sensible choice for a kitchen or bedroom.
Brightness, contrast, and color
The direct-lit panel has no local dimming and no HDR, so dark scenes look somewhat gray, and bright highlights don’t pop. Colors look natural but not especially rich. Brightness is adequate for a dim bedroom but struggles against sunlight.
Viewing angles
Viewing angles are narrow. The image fades and colors shift when you sit well off to the side, so place the TV where you’ll watch it from straight on.
Motion and gaming
The 60Hz panel handles TV shows and movies well, but fast sports and games show some blur. It works for casual gaming on older consoles or a Nintendo Switch. For a PlayStation 5 or Xbox Series X, see our best gaming TVs for PS5 and Xbox.
Sound
The two 8W speakers sound thin and shrill at higher volumes. For movies or music, connect a small soundbar to the ARC or optical port. A compact soundbar from Amazon fits neatly under a 40-inch screen.

Who should buy the Onn 40-inch TV?
Buy it if you find one cheap and need a simple streaming screen for a kitchen, dorm, guest room, or child’s bedroom. A 40-inch screen fits most small bedrooms well; our guide to the best TV size for a bedroom explains how to match screen size to your viewing distance.
Skip it if you want HDR movies, a wired internet connection, Bluetooth headphones, or decent built-in sound. In that case, a current Roku Select Series, Fire TV 2-Series, or a 43-inch 4K TV is worth the small extra cost.
Frequently asked questions
Is the Onn 40-inch TV 4K?
No, the Onn 40-inch TV isn’t 4K. The 40-inch Onn Roku TV has a 1080p Full High Definition panel. Walmart’s 4K Onn models start at 43 inches.
Does the Onn 40-inch Roku TV have Ethernet?
No, the Onn 40-inch Roku TV doesn’t have Ethernet. According to Onn’s spec sheet, it connects through Wi-Fi only. If your Wi-Fi is weak, a streaming stick with an Ethernet adapter is one workaround.
Are Onn TVs still Roku TVs?
Most new Onn TVs are no longer Roku TVs. Since late 2025, Walmart has shifted new Onn TVs to Vizio OS and Google TV, so the Roku models remain only as leftover or used stock.
How long is the Onn TV warranty?
Onn TV warranty terms vary by model and over time, so check the warranty section on the Walmart listing or in the box before you buy, especially for open-box units.
Final verdict
The Onn 40-inch Roku TV does a small job well: it puts a sharp 1080p picture and Roku’s easy streaming interface in a light, cheap package with three HDMI ports. The lack of HDR, Ethernet, and Bluetooth, plus weak speakers and narrow viewing angles, keep it in second-TV territory. With Walmart moving Onn to Vizio OS and Google TV, grab the Roku model only at a clearance price; otherwise, a current 40 to 43-inch TV offers more. Check the latest 40-inch smart TV prices on Amazon.
