Toshiba 43LF421U21 review: First thoughts

The 43LF421U21 delivers excellent viewing experiences and a smart engine that learns your taste as you enjoy your favorite TV shows and movies. The Alexa voice-controlled remote performs all the tasks you would expect to be able to do with a regular remote, but with the option of using your hands or voice.

This television comes with Wi-Fi connectivity, and it’s loaded with popular media streaming apps like Amazon Prime Video. It comes with a 28-inch TV stand that provides decent stability with little to no wobble. It comes with 400 x 200 VESA mounting holes.

The 43LF421U21 delivers 1080p HD pictures, with brilliant colors, rich contrast, and lifelike details. It was designed with performance and speed in mind, and it runs on a quad-core Multi-core GPU. The powerful processor leads to a fluid and responsive experience. It does not have the long lag associated with so many Smart TVs.

The color accuracy is just as impressive, with greens and flesh tones looking natural. It has a decent contrast ratio, leading to images with lots of depth. The black levels are okay, but it is only average when it comes to very dark scenes.

The brightness levels are impressive. Pictures are just as clear when viewing the TV in brightly lit rooms. It comes with a Film Mode function which works great with HD content. The glossy screen surface reflects nearby light, but it reduces most of the glare.

The viewing angles aren’t as impressive, and you’ll have to sit right in front of this TV to enjoy the best picture quality. It makes the 43LF421U21 better suited for bedrooms and gaming rooms where only one person would be using it most of the time. Viewing angles are extremely important when it comes to selecting a living room TV since you want something people seated at all corners to enjoy the same detailed pictures.

The 43LF421U21 handles motion well, with little blur. It does it better than most LCD TVs with a 60Hz frame rate. Our Toshiba 43LF421U21 review is just getting started. We’ll explore what the audio is like next.


The inbuilt audio system that comes with the 43LF421U21 is a little bit better than what you would expect in a budget TV. It’s good enough to enjoy movies, shows, or concerts, and the bass is surprisingly full. At the max volume, the TV is loud enough to fill up most rooms, but the sound quality does degrade as the volume is turned up.

User interface

Another cool thing we liked about the 43LF421U21 is the easy-to-use interface. Everything is self-explanatory and you can use verbal commands if you’re not a fan of remotes. The buttons are backlit so they are easy to see even in a dimly lit room.


The 43LF421U21 comes with three HDMI ports – one no component input, one composite input, and one Audio Return Channel. It also has a headphone out jack, which is not something you will find on many budget TVs. It means you can enjoy detailed audio without bothering anyone else in the room.

Other connections that come with the 43LF421U21 include an Ethernet port, a Wi-Fi adapter, an optical digital audio out port, and a USB port. It comes with casting capability, which allows you to push content you’re watching on your mobile device to the TV.


  • Fully functional Smart TV at a budget price
  • Responsive user interface
  • Clear detailed pictures
  • Comes with headphone out port


  • Poor viewing angles
