The Onn 50-inch 4K Roku TV is a Walmart house-brand budget TV, and in 2026 it suits a guest room or kid’s room better than a home theater. It became one of the cheapest ways to put a 4K smart TV in a living room or bedroom. During its run, Walmart sold it for roughly $170 to $250, and it still turns up as a restored or open-box unit. This Onn 50-inch TV review covers what you get for that price, where the TV cuts corners, how the Onn lineup has changed in 2026, and which budget 50-inch TVs on Amazon you should compare before you buy.
Quick verdict: The Onn 50-inch 4K Roku TV delivers the simple, ad-light Roku interface and a sharp 4K picture for very little money. Its dim panel, weak black levels, mediocre sound, and so-so input lag make it a better fit for a guest room or kid’s room than a home theater. Newer budget models from TCL, Hisense, Roku, and Amazon offer brighter pictures for similar prices. Check budget 50-inch 4K TV prices on Amazon.
Key takeaways
- What it is: A budget 50-inch 4K TV with Roku built in, a 60 hertz (Hz) panel, and no local dimming, sold under Walmart’s Onn brand.
- Price: Walmart sold it for roughly $170 to $250 during its run, and as of fall 2026 it turns up mainly as restored or open-box stock. Prices change often.
- Main weaknesses: A dim picture with poor black levels, narrow viewing angles, 32.1 milliseconds of input lag in Tom’s Guide’s testing, and thin speakers.
- Status: Walmart has shifted Onn TVs to Vizio’s operating system (Vizio OS) and Google TV, and Roku-powered 4K Onn sets had largely disappeared from Walmart shelves by October 2026.
- Bottom line: Newer budget 50-inch TVs from TCL, Hisense, Roku, and Amazon offer brighter pictures for similar prices.

Is the Onn 50-inch Roku TV still available in 2026?
Mostly no. After Walmart bought Vizio, the company began moving Onn TVs away from Roku. In late 2025, Walmart started selling Onn TVs powered by Vizio’s operating system (Vizio OS), and in mid-2026 it added Onn 4K quantum dot light-emitting diode (QLED) TVs that run Google TV, starting at about $248 for a 55-inch model, according to Cord Cutters News. By October 2026, Roku-powered 4K Onn sets had largely disappeared from Walmart shelves.
So if you find the Roku model, it’s likely leftover, restored, or open-box stock. That can still be a bargain, but check the return window and warranty first. If you prefer Roku specifically, Roku now makes its own budget Select Series TVs, and our guide to smart TVs vs. Roku TVs explains how the platforms differ. You can browse current Onn models at walmart.com.
Design and build quality
The Onn 50-inch TV uses a slim plastic frame with thin bezels. The cabinet measures 2.4 inches deep at its thickest point, with a small bulge at the bottom that houses the speakers and electronics. At about 25 pounds, one adult can lift and position it without much trouble.
The TV ships with two feet that mount near the edges, so you need a stand or dresser that’s nearly as wide as the screen. Owners often describe the feet as wobbly, which makes wall mounting a sensible choice. The back panel has standard Video Electronics Standards Association (VESA) mounting holes, so most budget wall mounts fit. Check the manual for the exact pattern before you order a bracket.
Port placement is a mild annoyance. The three HDMI ports face downward, which makes them awkward to reach once the TV sits against a wall. The USB port and a few other connectors face sideways and are easier to access.
Ports and connectivity
For a TV in this price range, the port selection covers the basics:
- Three HDMI ports, one with ARC for a soundbar
- One USB port for media playback
- Ethernet for a wired internet connection
- Optical digital audio output
- RF input for an antenna or cable
None of the HDMI ports support HDMI 2.1 features such as a 120Hz refresh rate or variable refresh rate (VRR), according to Tom’s Guide. That’s normal for a TV at this price, but it matters if you own a PlayStation 5 or Xbox Series X.
The TV has Wi-Fi but no Bluetooth, so you can’t pair wireless headphones directly. Roku offers a workaround: install the free Roku mobile app, pair your Bluetooth headphones with your phone, and turn on Private Listening. The app then streams the TV’s audio through your phone to your headphones.
Roku smart features
The Roku interface is the best thing about this TV. The home screen uses a simple grid of apps, menus are easy to learn, and it supports almost every major streaming service, along with free live channels through The Roku Channel. The included remote is basic but easy to use.
The TV doesn’t have a built-in microphone or a voice assistant. However, Roku TVs work with Amazon Alexa and Google Assistant through a separate smart speaker, so you can still turn the TV on, change inputs, or launch apps by voice if you own an Echo or Nest speaker. The Roku mobile app also works as a second remote with voice search and keyboard entry.
Owners and reviewers note that apps can load slowly on this TV, a common trait of budget Roku TVs with entry-level processors.
Picture quality and performance
Brightness and contrast
This is where the Onn TV shows its price. Tom’s Guide found it significantly dimmer than other TVs it tested that year, and its black levels were poor. In one dark scene, the reviewer lost the details of a fight sequence in a dark blue blur. Without local dimming, the TV can’t darken parts of the screen independently, so dark scenes look washed out and gray, and HDR content gains little over standard video. Our explainer on local dimming covers why this matters.
Color
Tom’s Guide measured 96.7 percent coverage of the standard Red Green Blue (sRGB) color space, which is lower than most competing 4K TVs. Colors look acceptable in bright, everyday content such as sitcoms, news, and sports, but the TV can’t show the wider range of colors that HDR movies use.
Viewing angles and uniformity
Viewing angles are limited. Tom’s Guide noted that brightness drops when you watch from the side, so viewers at the ends of a wide sofa will see a dimmer, flatter image. For the best picture, sit close to straight on.
Motion and gaming
The 60Hz panel handles casual viewing fine, though fast motion shows some blur. Tom’s Guide measured input lag at 32.1 milliseconds (ms), which is noticeably slower than the roughly 10 to 15 ms that better budget TVs reach in game mode. Casual gamers won’t mind, but competitive players should look elsewhere. Our guide to the best gaming TVs for PS5 and Xbox lists better options.
Sound
The built-in speakers produce clear dialogue but sound thin, with weak bass and some echo, and they don’t get very loud. A cheap soundbar connected through the ARC port makes a big difference. Try a budget soundbar from Amazon if you plan to use this TV for movies.
What owners report
Customer reviews on Walmart’s site are mostly positive about the value, but they point to some recurring issues:
- Unreliable Wi-Fi connections on some units
- Occasional audio lag or sync problems
- Remote pairing problems, especially when replacing the original remote
- Inconsistent quality control, with some units arriving with defects
- Mixed experiences with customer service

Who should buy the Onn 50-inch 4K Roku TV?
Buy it if you find one cheap, want a no-frills screen for a bedroom, dorm, guest room, or kid’s room, and value Roku’s easy interface over picture quality. A 50-inch screen suits most bedrooms; our guide to the best TV size for a bedroom helps you check your viewing distance. Skip it if you watch a lot of movies in a dark room, play fast-paced games, or want your TV to last as your main screen for years.
If you plan to wall mount it, a tilting TV wall mount on Amazon solves the wobbly-feet problem and makes the downward-facing HDMI ports easier to reach when you install it.
Frequently asked questions
Who makes Onn TVs?
Contract manufacturers make Onn TVs for Walmart, which owns the Onn private-label electronics brand. Walmart sells them in its stores and on walmart.com.
Do Onn TVs still use Roku?
Most new Onn TVs don’t use Roku anymore. Walmart has shifted the lineup to Vizio OS and Google TV models, and Roku-powered 4K Onn sets have become hard to find in stores as of late 2026.
Does the Onn 50-inch Roku TV have Bluetooth?
No, the Onn 50-inch Roku TV doesn’t have Bluetooth. You can still listen through Bluetooth headphones by using Private Listening in the Roku mobile app, or connect a soundbar through HDMI ARC or the optical port.
Is the Onn 50-inch TV good for gaming?
The Onn 50-inch TV is fine for casual gaming, but its 60Hz panel, lack of HDMI 2.1, and 32.1 ms input lag (measured by Tom’s Guide) make it a poor match for competitive play or next-generation consoles.
Final verdict
The Onn 50-inch 4K Roku TV does exactly what a bargain TV should: it gives you 4K resolution and Roku’s excellent streaming interface for very little money. Dim highlights, gray blacks, narrow viewing angles, and thin sound keep it from being a good main TV, and Walmart’s shift to Vizio OS and Google TV means the Roku version is fading from stores. If you can’t find a deal on one, a current budget 50-inch TV from TCL, Hisense, Roku, or Amazon will give you a better picture for about the same price.
