You’re standing in the middle of a Walmart aisle. It’s bright, loud, and you’re staring at a wall of glowing rectangles. There it is—the 40 inch onn roku tv. The price tag is so low it feels like a typo. You start doing the mental math. Is this actually a "real" TV, or is it going to die the moment the warranty expires?
I've been there. Most people look at the Onn brand and assume it's just cheap plastic destined for a landfill. But here’s the thing: in 2026, the gap between "budget" and "premium" isn't as wide as the marketing teams want you to believe. If you're looking for a secondary screen for a guest room, a dedicated gaming monitor for a kid, or just a solid TV that won't break the bank, you need to know what you’re actually buying.
It isn't a mini-LED powerhouse. It won't beat a $2,000 OLED in a dark room. Honestly, it's not trying to.
The Reality of the 40 inch onn roku tv Specs
Most tech reviewers ignore these smaller sets. They want to talk about 85-inch monsters with 8K resolution. But for a regular bedroom or a small apartment, 40 inches is often the "Goldilocks" size.
The current model (100058007) pushes a 1080p Full HD resolution. Some people hear "1080p" and think it's outdated because 4K is everywhere. On a 40-inch screen, however, the pixel density is tight enough that you really won't notice a lack of 4K unless you’re sitting three feet away. The colors are decent. The blacks are... okay. It uses a DLED (Direct Lit LED) panel, which means the backlighting is relatively even across the screen.
Here’s a quick look at what’s actually under the hood:
- Refresh Rate: 60Hz (Standard, but smooth enough for sports).
- Connections: 3 HDMI ports (one with ARC support), 1 USB, and a headphone jack.
- Audio: Dual 8W speakers. They’re fine for news, but thin for movies.
- Smart Features: Built-in Roku OS, which is arguably the best part of the package.
Why the Roku OS Saves This TV
If Walmart had tried to build their own smart interface, this TV would probably be a disaster. By partnering with Roku, they basically outsourced the brain of the operation to experts.
The interface is snappy. You’ve got access to basically every app imaginable—Netflix, Disney+, Max, and the Roku Channel. The 40 inch onn roku tv benefits from Roku’s constant software updates. You aren't stuck with a buggy, proprietary mess that stops working after a year.
One feature people often overlook is the Roku Mobile App. If you lose the remote (which happens constantly), you can use your phone. Even better, you can plug headphones into your phone and use "Private Listening" to watch TV while someone else is sleeping in the same room. It’s a lifesaver.
The Build Quality: Is It Actually "Cheap"?
Let's be real. It’s light. When you pick up the box, it feels like there might be nothing inside. The legs are plastic. The bezel isn't the thinnest on the market.
But does that matter?

If it’s sitting on a dresser or mounted to a wall (it’s VESA 200x200 compatible), you aren't touching it. It just needs to stay in one piece and show a picture. Some users have reported issues with vertical lines over long-term use, which is a common trade-off with budget panels. If you get a "lemon," it usually shows up in the first 30 days. That’s why buying it from a place with a solid return policy is non-negotiable.
Gaming on a Budget
Can you play a PS5 or Xbox Series X on this? Sure.
Will it look like a cinematic masterpiece? No.
The 60Hz refresh rate means you won't get that ultra-smooth 120fps gameplay. But for casual gaming, Nintendo Switch titles, or just some Fortnite, it's perfectly capable. The input lag is surprisingly low because there isn't a lot of heavy image processing slowing things down. It's a "raw" experience, which ironically works in favor of response times.
Comparing the Competition
You’ll see the 40 inch onn roku tv sitting right next to TCL and Hisense models.
- TCL: Usually a bit more expensive, slightly better build quality.
- Hisense: Often has better peak brightness but can have "dirty screen effect" on cheaper models.
- Onn: The price leader. You buy this when every dollar counts.
Common Myths vs. Hard Truths
Myth: It will explode in six months.
Truth: Most budget TVs use the same internal components as "mid-tier" brands. If you treat it well and don't leave it on 24/7 in a hot room, it can easily last 5+ years.
Myth: The sound is unusable.
Truth: It’s better than a tablet, but worse than a $100 soundbar. If you’re a movie buff, you’ll want external speakers. For the bedroom? It’s fine.
Myth: You need 4K at this size.
Truth: At 40 inches, the human eye struggles to see the difference between 1080p and 4K from a typical viewing distance of 6-8 feet. Save the money.
Actionable Steps for New Owners
If you've just unboxed your 40 inch onn roku tv, don't just leave the settings on "Vivid." That’s the "store mode" meant to look bright under fluorescent lights, but it makes people's skin look like orange peels.
- Change the Picture Mode: Switch to "Movie" or "Standard." It’ll look dimmer at first, but the colors will be way more accurate.
- Update the Software: Connect to Wi-Fi immediately and run a system update. Roku fixes bugs constantly.
- Check the Panel: Use a "backlight bleed test" video on YouTube. If you see massive white splotches in a dark room, take it back and swap it. Quality control on budget TVs can be hit or miss.
- Add a Cheap Soundbar: Even a $50 2.0 channel bar will make a massive difference if you find the built-in audio too tinny.
- Use eARC: If you do add a soundbar, use the HDMI (ARC) port. This lets your TV remote control the soundbar volume so you don't have to juggle two remotes.
This TV is a tool. It’s not a status symbol. It’s for the dorm room, the kitchen, or the guest house where you just want something that works. It delivers exactly what it promises: a big, clear picture and a smart interface for the price of a nice dinner out. Take the savings and buy some better popcorn.
