Onn Roku TV Review

If you’re looking for a TV that comes with all the perks of a high-end TV, Walmart’s Onn TV is not your best option. Onn TV series are affordable and perfect for people with a small budget who still want to feel what top-notch smart TVs have to offer.

Onn TV might be inexpensive, but unfortunately, it is a letdown when it comes to features, performance, and other cool stuff. The 50-inch model, for instance, comes at around $329, which is a great price when you consider TVs of similar size, but it falls short compared to similarly priced TVs.

One good thing about Onn TVs is that they are Roku TVs. This means they come pre-installed with Roku. This feature alone gives the TV a huge boost, but we’ll see in this detailed review if they are worth your time or money. 

Onn Roku TV

The Onn smart televisions are Roku-enabled, and if you’ve never used Roku before, you’re in for a treat. Roku offers thousands of free channels, as well as premium subscriptions to your favorite shows from Netflix, HBO, and other suppliers. It auto-updates and is controlled with a remote, allowing you to search for exactly what you want to see.

The following models in this review are 4k, except the 42-inch Onn model, which is 1080pi high definition. 

Onn 42 Inch Roku TV Review

This is the only Onn TV model on this list with a 1080p display. If you’re interested in the 4k wider screens, see the 50″ and 70″ listings below. 

The 1080p looks good but not good enough (especially if you have high standards). However, when combined with the Roku, which shows 4k content, it’s a lot more appreciable. The 8-watt speakers can cover a reasonable amount of ground but will not fill the room. You might want to consider buying a Soundbar or some external speakers.

In terms of gaming, we’d say it’s okay but not exceptional. It has a 60hz refresh rate, which is sufficient for gaming. However, a 120 Hz refresh rate would be preferable for a better experience. That’s not to suggest it’s a terrible thing; you’ll still have a good time gaming, but it won’t be as smooth as a 120 Hz display.

Overall, the performance of this TV is just about average, and that’s not entirely surprising going by the price. The picture quality will not win an award but is good enough to enjoy Roku TV shows and movies. Thanks to the collaboration with Roku, it’s still very relevant among budget smart TVs.

If the TV breaks or something happens, it’s easily replaceable. Lastly, if you’re a professional or competitive gamer, you want to skip Onn 42″ Roku TV. Its 60 Hz isn’t good up to standard for most games.

  • Wireless streaming
  • 60 Hz refresh rate
  • HDR display technology
  • 1080P resolution

Onn 50 Inch Roku TV Review

The thin appearance of the Onn 50 inch 4K Smart TV attracts buyers at first glance. The TV is 44.2 inches in length and 25.5 inches in height. The model is also very light.

The screen is encased in a gleaming plastic rim that adds to its appeal. If you’re going to install this Onn TV somewhere where a child or pet might run into it, we recommend using a 200 x 200 VESA wall mount.

For performance, don’t expect excellence, especially in terms of picture quality. Again, the price informs this. While Onn 50″ smart TV may not compete and feature in the best smart TVs list, it’s not bad. For its screen size, the 4k (3840 x 2160p resolution) is impressive up to a certain standard, and that’s it.

The TV’s brightness and colors are also some of the things you might find underwhelming. You might find that certain movies you watch don’t capture the ideal colors intended. Expect blurs, unsatisfying blacks, and less than desirable brightness.

The Onn 50-inch 4K Roku Smart TV, as its name suggests, takes advantage of Roku’s extensive app catalog. It supports the same library of streaming services as flagship products from prominent midrange brands such as Hisense and TCL.

The Onn 50-inch 4K Roku Smart TV’s smart home capabilities, or lack thereof, are where it falls short again. Many current smart TVs come with Amazon Alexa and Google Assistant built-in, but this one doesn’t.

If you don’t use smart home devices, this may not be an issue, but if you live in a house full of internet-connected devices, an Assistant-enabled TV like the TCL 3 Series would be a better fit.

Key Features

  • 50″ (49.5″ actual diagonal) 4K (2160P) UHD LED TV
  • 2160P resolution
  • VESA: 200 x 200 mm
  • Wireless streaming
  • 60 Hz refresh rate
  • DLED Display
  • Connections: 3 HDMI, 1 Composite, 1 USB, 1 Optical, 1 Coaxial/Cable, 1 LAN and Headphone

Our Verdict

If you’re searching for a low-priced set with access to Roku’s channels, the Onn 50-inch 4K Roku Smart TV from Walmart is a good choice. It’s one of the most cost-effective methods to upgrade to a smart TV, and its thin design certainly appeals.

If the picture or audio quality is important to you, you’ll want to pay a little extra and get anything from TCL’s 3 or 4 Series. 

Onn 70 Inch Roku TV Review

This is the biggest model of Walmart’s Onn TV series. The measurements of the model are 61.5 X 38.3 X 12.5 inches. Despite its size, it weighs only 45.2 pounds.

Onn 70′′ class 4K UHD, like other middle-range TVs such as Hisense and TCL, offers a high 4K Ultra-high-definition that produces more precise images. The screen is encased in a gleaming plastic rim that adds to its appeal.

Onn 70′′ class 4K UHD features three HDMI ports, one USB port, one composite, one coax, one headphone jack, and one headphone jack, unlike other variants. You can use the ports to connect external devices such as earbuds, a Fire Stick, and more.

Compared to other brands with above 98 sRGB, the Onn 70′′ class 4K UHD has 96.7 sRGB, limiting its visual capability. Additionally, this model operates at 60 Hz, which is lower than other variants that operate at 120 Hz. Consider alternative models if you’re searching for something to play high-end games on.

Some of the upsides of this TV include its large and thin size, perfect for large-sized rooms and TV time with more than a few people. You also get larger images because of the size. The 70″ also comes with impressive 10-watt speakers that provide good sound, so you might not need an external speaker or soundbar. Lastly, Roku adds to the overall value of the set.

Apart from the average picture quality, which cuts across the different models reviewed here, the stand needs some work. It’s not as strong and should probably not be trusted to do the heavy lifting if you have kids around.

This model comes with fewer HDMI connectors than the other two on this list, which is surprising since this is a more expensive model of the three. And lastly, we believe there is no difference between the 70 and 50 inches – perhaps just the size.

Key Features

  • 70″ (69.5″ actual diagonal) 2160p UHD LED TV
  • 4K UHD (2160p) resolution
  • DLED display
  • VESA: 400 x 200 mm
  • Wireless streaming
  • 60 Hz refresh rate
  • Connections: 3 HDMI, 1 composite, 1 USB, 1 LAN, 1 coaxial/cable, 1 optical and 1 headphone

Our Verdict

We were a little startled to learn that this Onn TV only has three HDMI ports rather than the four that the 50-inch model has. However, this model does come with 10-watt speakers, and the music quality is quite good.

There does appear to be a discernible difference in detail in the larger picture. Even though it has 96.7 sRGB constraints, it nevertheless produces a beautiful image.

We were a little unimpressed to learn that all of these devices share the same 60hz refresh rate. We’d expect a speed of 120 at the very least, and 240 would have been better. This isn’t a big deal for casual viewing, but if you’re searching for a high-end gaming screen, 60hz could be a massive issue.

The black hues are not as sharp, and you may need to experiment with the brightness to find the best setting. You get a lot of detail, but with the 70-inch, we expected more thrills and frills. We thought it could be better than the 50-inch because it’s bigger and has one less HDMI connector.

The included stand hasn’t changed much from the previous two models, except for the television weight, so this is a TV you’ll want to mount if you have cats chasing each other around the house or children.


This Onn TV is a good choice for those who can’t afford some of the top brands. If you’re looking for something more affordable, Onn TV is a good option. But if you’re looking for a smart TV with all the top-quality features, you might want to look elsewhere. We hope you found this review helpful.
