Walmart Onn 4k Plus Google TV Streaming Box Review

Walmart just refreshed their sub $30 Google TV device with the new Onn 4K Plus (compensated affilate link). These are designed mainly for situations where a TV’s smart features are outdated or no longer functional, and in that context, it ends up being a surprisingly capable solution that feels a lot more powerful than its predecessor.

You can see it in action in my latest video review.

The device itself is a small puck—slightly larger than the last version—with HDMI out, a USB-C port for power, and a reset button. Performance over Wi-Fi was surprisingly solid. It supports Wi-Fi 6 and pulled around 430 Mbps down and up.

The 4k Plus supports USB-C hubs for peripherals, and I was able to get Ethernet working through one, though compatibility was inconsistent depending on the adapter. It looks as though the port is limited to USB 2.0 speeds as the best I could get out of my adapter was 100 megabits per second.

Internally, this version runs on an Amlogic S905X5M processor with 2GB of RAM and 16GB of storage. That’s a bump up in both performance and storage compared to earlier models. It still won’t satisfy power users, but general performance is responsive, especially when navigating Netflix and other streaming apps. The interface felt much zippier than I expected for this price point.

It runs Android 14 under the hood, and the front-end experience is standard Google TV, which remains very ad-centric. You’re presented with promotions and suggestions based on viewing habits, and it integrates content from services that support Google’s recommendations. The usual suspects like Netflix, Disney+, and YouTube are present, although there are some quirks—Netflix shows can’t be added to the watchlist, for example. That’s a long-standing limitation tied to how Netflix handles integration.

The remote includes voice control, which worked well for searches, and a new “Free TV” button that jumps into Google’s curated free content offering. It’s not vastly different from what Roku or other aggregators do, but Google has added a prominent shortcut to it on the remote to steer users onto their free platform.

Video and audio performance was mixed depending on the app. Netflix ran fine with Dolby Vision and Atmos audio on my 4K setup, but Disney+ didn’t deliver Atmos, and also failed to switch into 24p mode for content that needed it. This isn’t unusual—frame rate switching has been a persistent issue on Android boxes. You can enable it in settings, but results still vary app by app. Netflix behaved the best in my testing.

Gaming was better than expected. Android games ran smoothly, and GeForce Now performed decently over Wi-Fi at 1080p60. There was one crash and reboot, possibly related to the 2GB RAM ceiling, but overall stability was reasonable. Emulation is limited; PlayStation 1 works, but GameCube and PS2 emulators wouldn’t install.

As a Plex client, it handled browsing quickly, which made navigating a large local library feel snappy. But it lacks features more serious users might expect—no support for Dolby Vision from Blu-ray rips or lossless audio passthrough. So while it’s fine for casual Plex use, it’s not going to replace a higher-end setup in a home theater environment.

This box isn’t for enthusiasts, but it’s the kind of product they might still find a use for in a guest room or second TV. For most people, especially anyone looking to upgrade an old smart TV without spending much, it feels like a substantial upgrade. Even if it’s not perfect, it is probably the most value packed TV box on the market.
