You're standing in the middle of a Walmart electronics aisle. It’s loud. The fluorescent lights are humming. You just need a decent screen for the bedroom or maybe a dorm, and you’re staring at a wall of 40-inch displays. Most people think this size is dying out because everyone wants a 75-inch monster that requires a construction crew to mount, but honestly? The 40-inch bracket is still the "sweet spot" for real life.
It fits on a standard dresser. You can carry it yourself. It doesn't cost a month's rent.
But here is the problem: 40 inches Walmart TVs are a minefield of weird brands and varying resolutions. If you grab the wrong one, you’re stuck with a "720p" muddy mess that looks like it belongs in 2012. You have to be careful. Walmart pushes their house brand, Onn., pretty hard, but they also stock TCL, Hisense, and Vizio. Each of these companies approaches the 40-inch limit differently. Some give you a "smart" interface that’s basically a billboard for ads, while others actually focus on the panel quality.
The Onn. Factor and Why Price Isn't Everything
Walmart’s own brand, Onn., is the elephant in the room. They are cheap. Sometimes suspiciously cheap. We are talking "under 150 dollars" cheap during a good sale. Now, if you just want a screen to play the news in a breakroom, go for it. But if you’re actually planning to watch a movie, you need to look at the refresh rate and the operating system. Most of the 40-inch Onn. models use Roku TV.
Roku is great. It’s simple. It doesn't lag nearly as much as the proprietary software you find on some off-brand budget sets.
However, the hardware inside an Onn. TV is often the bare minimum. You'll notice the viewing angles are... narrow. If you aren't sitting directly in front of it, the colors start to shift and look washed out. It’s a trade-off. You save fifty bucks, but you lose that crispness you see on the slightly higher-end TCL or Hisense models sitting right next to it on the shelf.
Resolution Traps to Avoid
Let's talk about 1080p versus 720p. In 2026, 720p shouldn't even exist in a 40-inch size, yet you’ll still see them lurking on the bottom shelf at Walmart. Don't do it. At 40 inches, the pixel density of 720p is low enough that you can actually see the "screen door effect" if you’re sitting within six feet. Always check the box for "Full HD" or 1080p.
Wait.
What about 4K?
Finding a 4K TV in a 40-inch size is actually harder than you’d think. Most manufacturers jump from 1080p at 40 inches straight to 4K at 43 inches. That three-inch difference is massive in the manufacturing world. If you find a 40-inch 4K TV at Walmart, it’s usually a specific model from a brand like Hisense or a smaller tech player trying to fill a niche. For most people, 1080p is totally fine for this size, but if you’re using it as a giant computer monitor, you really want that 4K density.
Why 40 Inches Walmart TVs are the King of Gaming Nooks
Gaming isn't just for the living room anymore. A lot of people are setting up "sim rigs" or small desk setups where a 55-inch screen would literally give them a headache. This is where the 40-inch Walmart inventory shines.
Take the TCL 3-Series or 4-Series.
TCL has basically mastered the art of the budget gaming screen. Their 40-inch models usually have a dedicated "Game Mode." It’s not just a marketing buzzword. It actually reduces input lag by turning off unnecessary image processing. If you’re playing something fast like Call of Duty or Apex Legends, that split-second difference between pressing a button and seeing the action on screen matters.
Vizio is another one to watch here. Their D-Series often pops up in Walmart's circulars. Vizio tends to put a lot of focus on their "SmartCast" system. Honestly? It can be a bit buggy compared to Roku, but they often include better local dimming or backlight control than the super-cheap brands. This means blacks look blacker, not just a cloudy dark grey.

The Sound Quality Struggle
Here is a truth nobody likes: every 40-inch TV at Walmart sounds like a tin can.
The physics just don't work. The TVs are too thin to hold decent speakers. Manufacturers know that if you’re buying a budget 40-inch set, you probably aren't hooking it up to a $500 Sonos bar. So, they put in the cheapest 5-watt or 8-watt speakers they can find.
If you’re buying one of these, budget an extra $50 for a small soundbar. Even a cheap one will beat the internal speakers. Some of the Hisense models at Walmart have "DTS Virtual:X," which tries to trick your ears into thinking there is surround sound. It’s okay. It’s better than nothing. But it won't replace a real speaker.
Smart Platforms: Roku vs. Google TV vs. WebOS
When you buy a TV at Walmart, you aren't just buying hardware. You're buying an ecosystem.
- Roku TV: Found in Onn., TCL, and Hisense. It is the gold standard for budget TVs. It’s fast. It works.
- Google TV: Becoming more common in Hisense and Sony models. It’s better for "discovery." It suggests shows based on what you like, but it can feel a bit "heavier" on cheaper processors.
- Vizio SmartCast: It’s fine, but it relies heavily on "casting" from your phone. If you hate using your phone as a remote, avoid this.
Most people prefer Roku because the remote is simple. It has about five buttons. Your grandma can use it. Your toddler can use it. In the 40-inch market, simplicity usually wins because these aren't typically the primary "home theater" screens where you want to spend twenty minutes tweaking settings.
Checking the Ports (The Part Everyone Forgets)
You get home. You unbox your new 40-inch find. You go to plug in your Soundbar, your Xbox, and your cable box.
Uh oh.
Only two HDMI ports.
This is a classic "budget TV" move. To save money, manufacturers will strip out the ports. Always look at the back of the display model or the side of the box. You want at least three HDMI ports. If you can find one with an eARC (Enhanced Audio Return Channel) port, grab it. It makes connecting a soundbar so much easier because your TV remote will automatically control the soundbar volume without any extra setup.
The "Walmart Special" and Black Friday Leftovers
Walmart is famous for having "special" model numbers. You might see a TV that looks exactly like one at Best Buy, but the model number is off by one digit. Usually, this means it was manufactured specifically for Walmart to hit a certain price point. Sometimes they swap out a premium remote for a basic one, or they use a slightly different plastic for the stand.
It’s rarely a deal-breaker, but it’s why "price matching" can be tricky.
If you see a 40-inch TV that seems like an insane deal, check if it’s a "Refurbished" unit. Walmart’s website is flooded with third-party sellers now, much like Amazon. If you’re buying in-store, you’re safe. But if you’re ordering online, make sure it says "Sold and Shipped by Walmart" to ensure you have a real warranty and an easy return path.
Real-World Use Cases: Where 40 Inches Makes Sense
I’ve seen people try to put a 40-inch TV in a massive living room and sit 12 feet away. Don't do that. You’ll be squinting at the subtitles.
A 40-inch screen is perfect for:

- The Kitchen: High enough to stay out of the way, big enough to see a recipe from the stove.
- The Home Office: It’s the ultimate "second monitor" for keeping a YouTube stream or the news running while you work.
- The Kid's Room: It’s cheap enough that if a Wii remote goes through the screen, your heart won't break (well, not as much).
For a bedroom, 40 inches is actually quite large if the room is standard size. It’s immersive without being overwhelming. If you’re mounting it, remember that 40-inch TVs are incredibly light. Most of them weigh less than 15 pounds. You don't need a heavy-duty mount; a basic $20 VESA wall mount from the same Walmart aisle will hold it just fine.
Actionable Steps for Your Purchase
Before you head to the checkout with that 40-inch box, do these three things:
- Check the resolution on the box. If it doesn't say "1080p" or "FHD," put it back. 720p is a relic of the past and you deserve better.
- Look at the remote. Budget TVs often have infrared remotes that you have to point directly at the sensor. If it’s a Roku TV, try to see if it’s the "Voice Remote" or the basic one. The voice remote is worth the extra $10 every single time.
- Test the return policy. Walmart is generally great with returns, but keep your box for at least 30 days. These budget panels sometimes have "dead pixels" that you won't notice until you’re lying in bed at night watching a dark scene. If you see a bright green dot that won't go away, take it back.
Shopping for 40 inches Walmart TVs doesn't have to be a gamble. Stick to the name brands like TCL or Hisense if you care about picture quality, or go with Onn. if you just need the cheapest possible portal to Netflix. Just don't settle for 720p. You're better than that.
