Let’s be honest. Nobody buys an onn roku tv 24 inch because they’re looking for a "home theater experience." You aren't expecting a 100-inch laser projector or an OLED that costs as much as a used Honda. You probably just need something for the kitchen, the garage, or maybe a kid’s bedroom where a giant screen would basically be a structural hazard.
But here’s the thing: because it’s a "budget" TV—and I mean really budget—people tend to either overestimate what it can do or, more commonly, assume it’s total junk. Neither is quite right.
I’ve spent plenty of time digging into why this specific 24-inch model (often listed as model 100012590) survives in a market obsessed with 8K resolution and AI-enhanced everything. It turns out, being "just okay" is actually a superpower when the price is right.
The 720p Elephant in the Room
If you look at the specs, the first thing that jumps out is the resolution. It’s 720p. In 2026, saying a TV is 720p sounds a bit like saying your car has a cassette player.
But wait.
On a 24-inch screen, the pixel density is surprisingly tight. You have to remember that 1080p (Full HD) only really starts to matter once you cross the 32-inch threshold, or if you’re using the TV as a dedicated computer monitor while sitting twelve inches away. For watching the news while you’re frying bacon or letting a toddler watch Bluey, 720p is perfectly fine. Honestly, most people can't tell the difference at this size from five feet away.
The refresh rate is a standard 60Hz. It’s not going to give you that buttery smooth motion for competitive Call of Duty sessions, but for casual streaming? It’s solid.
What’s Under the Hood (The Good and the Meh)
- The Screen: It uses a DLED (Direct LED) display. This basically means the LEDs are behind the screen rather than just along the edges. It helps with brightness uniformity, though don't expect deep, "inky" blacks.
- Port Selection: You actually get 3 HDMI ports. That’s more than some high-end laptops have these days. You also get a USB port, a composite input (for those ancient Nintendo Wiis), and an optical output.
- Wireless: It’s got Wi-Fi, obviously, because it’s a Roku TV. But don't go looking for an Ethernet port; this little guy is strictly a wireless warrior.
Why the Roku OS Saves the Day
The real reason the onn roku tv 24 inch is even worth talking about isn't the hardware. It’s the software. Roku is, and arguably remains, the most user-friendly smart TV platform for the average human.
The interface is basically just a grid of big, chunky icons. There aren't any weird "trending now" sidebars that take five seconds to load while the processor struggles to breathe. It just works.
If you’ve ever tried to navigate a cheap Android TV or a proprietary OS on a bargain-bin screen, you know the pain of "remote lag." You press a button, wait two seconds, nothing happens, so you press it again—and then the TV jumps three menus ahead.
The Roku OS on this model stays relatively snappy because it’s not trying to do too much. It handles Netflix, Hulu, and the Roku Channel (which has a surprising amount of free, albeit ad-supported, content) without breaking a sweat.
The Remote and the "Private Listening" Hack
The remote that comes in the box is the standard, simplified Roku remote. It’s infrared (IR), meaning you actually have to point it at the TV. No hiding under the covers and changing the channel.
However, the real "pro tip" for this TV is the Roku Mobile App.
Since the built-in speakers are, frankly, pretty "tinny" (they’re tiny 3W or 5W drivers, what do you expect?), you can use the app for Private Listening. You plug your good headphones into your phone, and the audio streams from the TV to your phone via Wi-Fi. It's a game-changer if you’re trying to watch a late-night show in bed without waking up your partner.
The Sound Quality Reality Check
Look, we have to talk about the speakers. They are not good.
They’re okay for dialogue. You’ll hear what the news anchor is saying. But if you’re watching an action movie where things are exploding, it’s going to sound a bit like a bumblebee in a soda can.
The Fix: Since there’s a 3.5mm headphone jack and an optical port, you can easily hook up a cheap pair of computer speakers or a small soundbar. Even a $20 pair of desktop speakers will make this TV sound ten times better.
Where This TV Actually Belongs
Don't put this in your living room. Just don't.
But if you need a screen for a very specific, utilitarian purpose, the onn roku tv 24 inch is a champion of the "secondary space."

- The Home Gym: It’s light. Like, really light (about 6 pounds). You can mount it on a cheap VESA 100x100 wall mount in about ten minutes and watch workout videos without cluttering up the floor.
- The Kitchen: It fits under most standard cabinets.
- The Travel Trailer: Because it’s small and energy-efficient (costing roughly $8-$10 a year to run), it’s a favorite for RV owners.
- The "Dumb" Monitor: If you have an old PC that just needs a display for basic tasks, the HDMI inputs make this a functional, if low-res, monitor.
The Competition: Onn vs. The World
You’ll see similar 24-inch models from brands like Insignia (Best Buy’s brand) or Vizio.
Vizio’s D-Series often offers 1080p at this size for maybe $20-$30 more. Is it worth the jump? If you’re using it as a computer monitor, yes. If you’re just watching The Office on a loop while you fold laundry, probably not.
Insignia uses the Fire TV platform. Some people love Alexa integration, but the Fire TV interface is significantly more "cluttered" with ads than Roku. If you want simplicity, stick with the Onn.
Real-World Reliability
One thing to watch out for: Onn is a Walmart brand. They aren't built to last twenty years.
I’ve seen reports of the Wi-Fi card getting a bit flaky after a year or two. If that happens, you can usually fix it by just plugging a $20 Roku Express stick into one of the HDMI ports, effectively bypassing the internal smarts but keeping the same interface you’re used to.
Also, the power supply is often an external "brick" rather than a standard plug. It’s a bit of a cable management annoyance, but it keeps the TV itself thinner and cooler.
Actionable Next Steps
If you’re ready to pull the trigger on an onn roku tv 24 inch, keep these three things in mind to get the most out of it:
- Check the VESA size: If you’re mounting it, make sure your mount supports 100mm x 100mm. Many "small" mounts only go up to 75mm.
- Update immediately: The first thing you should do after plugging it in is run a software update. Out-of-the-box Roku firmware can be buggy and slow; the latest patches usually smooth out the navigation.
- External Audio is key: If this is going to be your primary "bedroom" TV, budget an extra $30 for a small soundbar or even just use the Roku app's private listening feature. Your ears will thank you.
Basically, as long as you know you're buying a utility player and not a star athlete, you won't be disappointed. It's a screen that gets out of its own way and lets you watch what you want for less than the cost of a decent pair of shoes.
