ONN and Westinghouse sit at the bottom of the TV price chart, and that’s exactly why they sell so well. I’ve spent the past year tracking both brands as they go through major platform transitions, and the 2026 lineup looks different from what most comparison articles still describe.
Here’s what changed: Walmart acquired Vizio for $2.3 billion in December 2024, and new ONN models now run Vizio OS (SmartCast) alongside existing Roku models. Westinghouse, meanwhile, is shifting newer TVs to Xumo TV while keeping QLED Roku models in the lineup.
- ONN 65-inch 4K Roku TVs cost ~$278 at Walmart — roughly $50 less than comparable Westinghouse models at that size
- Westinghouse sells QLED 4K models — their Roku-powered QLED line starts around $229 for a 43-inch set on Amazon
- ONN is transitioning to Vizio OS — new 2025-2026 models run SmartCast, while older stock still runs Roku
- Westinghouse newer models use Xumo TV — Comcast’s EntertainmentOS replaces Roku on their latest sets, adding Dolby Atmos support
- ONN is Walmart-exclusive — Westinghouse sells at Amazon, Walmart, and Best Buy, giving it wider availability
#Which Brand Offers Better Picture Quality?
Both brands use LED-backlit LCD panels. Neither sells OLED. But Westinghouse now offers QLED models with quantum dot color enhancement, which ONN doesn’t match in its current lineup.
On standard LED models, I noticed ONN TVs produce slightly deeper blacks and better contrast. Text rendering looked sharper on the ONN 50-inch 4K I tested, with cleaner edges on UI elements and streaming menus. Skin tones came through more naturally, and shadow detail held up better in dark movie scenes.
Westinghouse’s QLED sets close that gap. The quantum dot layer pushes color volume higher than any ONN model I’ve seen, and peak brightness runs noticeably hotter. If you’re comparing LED-to-LED at the same price, ONN edges ahead. But Westinghouse’s QLED line at $229 for 43 inches delivers color accuracy that punches above its price class.

| Picture Quality | ONN (LED) | Westinghouse (LED) | Westinghouse (QLED) |
|---|---|---|---|
| 4K Resolution | Yes | Yes | Yes |
| HDR Support | HDR10 | HDR10 | HDR10 |
| Contrast | Good | Average | Good |
| Black Levels | Deeper | Shallow | Moderate |
| Color Volume | Standard | Standard | Enhanced (QD) |
| Peak Brightness | Moderate | Moderate | Higher |
#How Do the Smart Platforms Compare?
This is where 2026 gets complicated. Both brands are mid-transition.
ONN’s platform split: Older ONN TVs (and current budget models) run Roku OS. Newer 2025-2026 models, including the SGQ, MQP, and SQ series, ship with Vizio OS (SmartCast) or Google TV. Walmart hasn’t fully retired Roku from the ONN lineup yet, so what you get depends on which model you buy.
Westinghouse’s platform split: Legacy models run Roku TV. The 2025+ lineup, including 58-inch 4K sets at Best Buy, uses Xumo TV (powered by Comcast’s EntertainmentOS). Xumo bundles 300+ free streaming channels alongside Netflix, Disney+, and YouTube.
I tested both Roku and Xumo side by side. Roku wins on polish. Its cross-app search works better, and the channel library dwarfs what Xumo currently offers. That said, Xumo TV packs in features Roku lacks, like built-in Dolby Atmos passthrough on supported Westinghouse models, and the interface itself feels clean enough for daily use.
If you want the most predictable smart TV experience right now, grab an ONN or Westinghouse model that still runs Roku. If you don’t mind a newer platform, Westinghouse’s Xumo sets add Dolby Atmos support that Roku models skip.
For remote pairing issues on ONN Roku models, I’ve covered fixes in the ONN TV remote not working guide.
| Smart Features | ONN (Roku) | ONN (Vizio OS) | Westinghouse (Xumo) |
|---|---|---|---|
| App Library | 10,000+ channels | Major apps + SmartCast | 300+ free + major apps |
| Voice Control | Roku Voice Remote | Vizio Voice | Xumo voice search |
| Dolby Atmos | No | Select models | Yes |
| AirPlay 2 | Yes (Roku) | Yes (SmartCast) | No |
| Chromecast | No | Yes (built-in) | No |
#How Does Audio Performance Compare?
Budget TV speakers won’t replace a soundbar. That said, both brands produce clearer dialogue and better mid-range response than I expected at these price points.
ONN’s Vizio OS models inherit SmartCast’s audio processing, which includes virtual surround modes on select sets. The older Roku-based ONN TVs lack this entirely. If you’re buying ONN specifically for better audio, confirm the model runs Vizio OS before checkout.
Westinghouse’s Xumo TV models support Dolby Atmos passthrough via HDMI eARC. That’s a legitimate advantage if you plan to connect a Dolby Atmos soundbar. Their Roku models don’t have this feature, so again, the platform matters.
If your TV handles all your audio without external speakers, ONN’s Vizio OS sets sound marginally fuller. If you’re pairing with a Dolby Atmos soundbar, Westinghouse Xumo models pass through spatial audio that ONN Roku sets can’t. Having no sound on your ONN TV? That’s usually a fixable settings issue, not a hardware defect.
#Design and Build Quality
Westinghouse TVs look more polished. Their 2025 Xumo models use slimmer bezels and metal-accented stands that blend into living room setups. Cable management is cleaner on most Westinghouse stands I’ve handled.
ONN TVs are all-plastic. The bezels run thicker, the stands are basic V-shaped feet, and there’s no cable routing. For a bedroom or secondary room, that’s fine. For a main living space where the TV sits on display, Westinghouse builds a better-looking set.
Both brands feel sturdy enough. I wouldn’t worry about durability from either at these prices.
#Pricing and Where To Buy
This is where the brands diverge most.
ONN is a Walmart exclusive. You won’t find ONN TVs at Best Buy, Amazon, or anywhere else. Current pricing:
- ONN 43-inch 1080p Vizio OS: ~$148
- ONN 50-inch 4K Roku: ~$198
- ONN 65-inch 4K Roku: ~$278
Westinghouse sells across Amazon, Walmart, and Best Buy. Wider distribution means more price competition:
- Westinghouse 43-inch 4K QLED Roku: ~$229 (Amazon)
- Westinghouse 50-inch 4K Roku: ~$219 (Walmart)
- Westinghouse 58-inch 4K Xumo: ~$299 (Best Buy)
ONN wins on raw price. Westinghouse wins on availability and the option to shop sales across multiple retailers. If you already have a Walmart+ membership, ONN’s pricing becomes even more attractive with free shipping.

#Warranties and Support
Both brands include a standard 1-year manufacturer warranty. Neither offers standout customer service.
ONN warranty claims go through Walmart, which makes returns and exchanges more convenient if you live near a store. You can walk in with the TV and swap it. Westinghouse handles claims through their own depot process, which means shipping the set back.
For a $200-300 TV, I’d recommend a protection plan from your retailer. Walmart’s Allstate plan and Amazon’s extended warranty both run $20-40 for 3 years of coverage. Budget panels use lower-grade components, and a year of coverage doesn’t leave much margin.
#What About Connectivity and Ports?
Both brands cover the basics. You’ll get 2-3 HDMI ports (some Westinghouse models offer 4), USB, Wi-Fi, Bluetooth, and HDMI ARC on most 4K sets. Ethernet is available on select models from both.
The real connectivity difference ties back to smart platforms. ONN Vizio OS models include Chromecast built-in and AirPlay 2 for casting from phones and laptops. ONN Roku models support AirPlay but not Chromecast. Westinghouse Roku models also support AirPlay but not Chromecast.
If casting from Android devices matters to you, an ONN Vizio OS model is the only option here with native Chromecast. If you’re having Wi-Fi connection issues on an ONN set, I’ve written a fix guide for that.

#Bottom Line
ONN and Westinghouse both sell capable 4K TVs under $300. The right pick depends on what you prioritize.
Go with ONN if price is the deciding factor. A 65-inch 4K set for $278 at Walmart is hard to beat, and the picture quality on ONN’s LED panels holds up well for everyday streaming. If you’re in Walmart’s ecosystem, returns are painless and the newer Vizio OS models add Chromecast and AirPlay 2.
Go with Westinghouse if you want QLED color at a low price, Dolby Atmos support on Xumo models, or the flexibility to price-shop across Amazon and Best Buy. Their build quality also edges ahead for living room setups where the TV stays visible.
One more thing: both brands are mid-platform transition. Before you buy, check whether the specific model runs Roku, Vizio OS, Xumo, or Google TV. The platform affects your app access, voice control, and casting options more than the brand name on the bezel. If your ONN TV won’t turn on after purchase, that guide walks through every fix.
#Frequently Asked Questions
#Do ONN TVs run Android TV?
No. ONN TVs have never run Android TV. Older models run Roku OS, and newer 2025-2026 models ship with Vizio OS (SmartCast) or Google TV. Walmart’s acquisition of Vizio in December 2024 shifted the platform direction away from Roku on newer sets.
#Does Westinghouse make QLED TVs?
Yes. Westinghouse sells QLED 4K Roku TVs starting around $229 for a 43-inch model. The quantum dot layer improves color volume and brightness compared to their standard LED sets. These are available primarily on Amazon.
#What smart platform do new Westinghouse TVs use?
Newer 2025+ Westinghouse models run Xumo TV, which is Comcast’s EntertainmentOS platform. It includes 300+ free streaming channels, major apps, and Dolby Atmos support. Older inventory still runs Roku TV.
#Can you only buy ONN TVs at Walmart?
Yes. ONN is Walmart’s house brand, sold exclusively through Walmart stores and walmart.com. You won’t find ONN TVs at Amazon, Best Buy, or other retailers. Westinghouse has wider availability across all three.
#Do Westinghouse Xumo TVs support Dolby Atmos?
Yes. Westinghouse’s Xumo TV models support Dolby Atmos passthrough via HDMI eARC. Their older Roku-based models don’t have this feature. If spatial audio matters, verify the model runs Xumo before purchasing.
#Are ONN and Vizio now the same company?
Not exactly. Walmart acquired Vizio for $2.3 billion in December 2024, making both ONN and Vizio Walmart-owned brands. They remain separate product lines with different price positioning. ONN targets the ultra-budget segment, while Vizio covers mid-range. New ONN models borrow Vizio’s SmartCast software.
#How long do ONN and Westinghouse TVs typically last?
Expect 4-7 years with normal use. Both brands use lower-cost LED panels and components that may develop backlight issues or board failures sooner than premium brands. A 3-year extended warranty from your retailer ($20-40) covers most common failures beyond the included 1-year manufacturer warranty.
