10 Best 40 Inch Smart Tvs 2025 in the United States

The INSIGNIA 40" Class F20 Series is a solid choice if you're looking for a full HD smart TV that balances picture quality and smart features at an affordable price. It offers a 1080p resolution, which means you get clear and sharp images, though not the ultra-high detail of 4K models. The LED-backlit screen provides good color and contrast for everyday viewing, but it lacks HDR support, so the picture might not have the extra brightness and color depth seen in higher-end TVs. The 60 Hz refresh rate is standard, suitable for watching movies and TV shows, though it may not be ideal for fast-paced gaming or sports where smoother motion is preferred.

The built-in Fire TV platform is a strong point here, giving easy access to popular streaming services like Netflix, Prime Video, and Disney+, plus Alexa voice control for convenient navigation and smart home integration. Connectivity includes Bluetooth and Wi-Fi, allowing for wireless streaming and pairing with other devices. While the sound quality isn't highlighted as a strong feature, you can expect decent audio for casual viewing but might want external speakers for a richer experience. The viewing angle is typical for LED LCD screens, so the picture quality may drop when viewed from the side.

In terms of design, the TV is slim and straightforward, fitting well in most rooms without being bulky. This TV is a good fit for anyone wanting a dependable 40-inch smart TV primarily for streaming and regular TV watching, without needing 4K resolution or advanced gaming features.

The Amazon Fire TV 40" 2-Series is a solid choice for anyone seeking a compact smart TV with easy access to a large variety of streaming services. With a Full HD resolution and support for HDR, it delivers vibrant picture quality that enhances your viewing experience. The inclusion of the Fire TV platform allows you to stream from popular services like Netflix, Prime Video, and Disney+, making it versatile for entertainment needs.

One of the standout features is the Alexa Voice Remote, making it incredibly user-friendly; you can easily navigate and control smart home devices with voice commands. The TV also supports multiple connectivity options, with two HDMI ports for devices like gaming consoles and an Ethernet port for reliable internet access.

The refresh rate of 60 Hz might not be ideal for fast-paced gaming or sports, as it may lead to motion blur. Additionally, while the sound quality is decent with Dolby Digital support, the built-in 16W speakers may not provide the immersive audio experience that some users look for. For enhanced audio, you'll want to connect a soundbar or external speakers. In terms of design, the TV is lightweight and can be easily wall-mounted or set up using the included stand. Its sleek black plastic finish might not appeal to everyone. This TV is suited for casual viewers who enjoy streaming content and want a user-friendly interface. If your focus is on high-end gaming or superior audio quality, you might want to consider options in a higher price range.

The Samsung 40-Inch Full HD F6000 Smart TV is a solid choice if you want a reliable mid-range smart TV with good picture quality and smart features. Its 1080p resolution offers clear and sharp images, which is ideal for a 40-inch screen size—perfect for bedrooms or smaller living rooms. Thanks to HDR and Mega Contrast, you’ll notice better brightness and deeper blacks, adding more life to movies and shows. The TV runs on Samsung’s Tizen OS with One UI, an easy-to-use platform that gives quick access to popular apps and an impressive range of free channels, so you can find plenty to watch without extra subscriptions.

Connectivity-wise, it has Bluetooth, Wi-Fi, USB, HDMI, and Ethernet ports, allowing you to connect various devices smoothly. The 60 Hz refresh rate is standard for this size and category, suitable for everyday TV watching, though it might not be the best for fast-paced gaming or sports where higher refresh rates shine. Sound quality is enhanced with Samsung’s Object Tracking Sound Lite and Q Symphony compatibility, which means it delivers directional sound for a more immersive experience and works well with certain soundbars (sold separately). The slim, bezel-less design looks modern and keeps the focus on the screen.

The viewing angles are typical for LED TVs, meaning image quality can drop if you’re watching from far to the side. Also, while the built-in speakers are decent, they might not satisfy those wanting powerful audio without external speakers. Security features like Samsung Knox provide peace of mind by protecting your data and connected devices. This TV suits casual viewers who want a user-friendly smart TV with good picture and sound in a compact size, but serious gamers or cinephiles looking for 4K resolution or higher refresh rates might want to explore other options.
