The details

Have you been planning to cut the cord but don’t want to switch to a streaming service just yet? If you do, you should look for a tv compatible with indoor antennas, like Toshiba 43LF421U21.

This smart TV can be connected to any HD antenna, and this gives you easy access to a ton of over-the-air channels that are available for free. Here are other features you can expect from Toshiba 43LF421U21 tv.


When it comes to design, this TV has a fairly basic design. It has no bells and whistles, but it’s solidly-built and is sure to give you years of service.

Made primarily of plastic, the TV boasts a lightweight profile. The stand offers ample support, keeping the TV stable at all times. The only drawback is that it lacks a cable management feature, so if you’re not careful, the cords may become tangled quite a bit.

If you view the TV from the side, you’ll notice that it’s pretty thick. As a result, it protrudes slightly when mounted on a wall.


As we touched on earlier, the Toshiba 43LF421U21 doesn’t have any frills. Unlike its higher-priced siblings, this one doesn’t employ quantum dot technology, which would otherwise improve its color pallet.

It’s a simple 60 Hz display with a basic LED backlight, which is not as advanced as the full-array local dimming present in other TVs. Given these missing elements, it’s not surprising that its picture performance is a little wanting. In fact, its resolution is rated as 720p, so it may not display the sharpest images.

On a more positive note, the TV comes with a remote control that supports Alexa. This lets you issue most commands using only your voice.

The convenience that comes with using this voice assistant technology is massive. Not only can you control most of the TV functions but you can also launch buttons for streaming platforms like HBO, Netflix and Prime Video.

Ease of use

As we’ve come to expect of Fire TV models, the Toshiba 43LF421U21 is not difficult to set up.

The rear of the TV is fitted with three HDMI inputs, an optical audio output and a USB port. This makes it easy to connect any device you wish to. Also located on the back is an Ethernet port, an RCA composite video input and an antenna.

For navigation, this TV uses the Amazon Fire TV platform. If you’re planning to perform transactions like purchasing media or downloading apps, you’ll need to have an Amazon account. The good news is that if you’re on Amazon Prime membership, you’ll have unlimited access to a broad range of streaming movies, music and TV shows.

Important to note though is that you can choose to use your Toshiba Fire TV Edition without an Amazon account. You can opt for the Basic mode that allows you to use it as an ordinary TV. However, this eliminates the majority of streaming services and online features from the OS.


This is one of Toshiba’s biggest selling points. With a price tag that hovers around $200, it’s one of the least expensive TVs on the market.

And except for the resolution, which is below the average of 1080p, it has a pretty cool set of features. You get a reasonably-sized 31.5-inch screen that comes with an Alexa-enabled remote and so much more.

Final verdict

The Toshiba 43LF421U21 is designed for homeowners who’d like the opportunity to connect their HD antenna and enjoy free over-the-air channels. While it doesn’t have cutting-edge technologies, its minimalist design and Fire TV integration are adequate for its price.
