10 Best 40 Inch Smart Tvs 2025 in the United States

The VIZIO 40-inch Full HD Smart TV stands out in the compact smart TV category with its combination of features tailored for streaming and gaming. The Full HD resolution offers a noticeable clarity improvement over standard HD, providing vibrant colors and deep contrasts thanks to its Full Array LED Backlight and Active Pixel Tuning. Users can easily access a wide range of built-in apps from popular streaming services, allowing for convenient viewing of over 15,000 movies and shows, alongside 275 free channels through the WatchFree app.

One of the significant strengths is its gamer's edge with HDR10 support and Auto Low Latency Mode, ensuring smooth performance when paired with gaming consoles. Its Bluetooth capability enhances the listening experience, allowing users to connect headphones for a more personalized audio setup. The Smart TV is also designed for integration with smart home systems, compatible with Apple AirPlay 2 and voice assistants like Amazon Alexa and Google Assistant, which can streamline your viewing experience.

Despite its strengths, there are some limitations to consider. The refresh rate of 60 Hz might not satisfy users looking for ultra-smooth action in fast-paced media, especially in gaming. Additionally, while the audio quality is enhanced with DTS Virtual:X, some users might find the need for an external sound system to achieve a more immersive sound experience. The design, although modern with its ThinFrame, may not appeal to everyone, and as a 40-inch model, it’s more suited for smaller living rooms or bedrooms.

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 Roku 40-Inch Select Series Smart TV offers a solid choice for those looking for an affordable and easy-to-use 40-inch smart TV. Its Full HD 1080p resolution provides clear and sharp picture quality suitable for everyday TV watching, though it lacks the higher resolution (4K) seen in some modern TVs. The TV runs on the Roku platform, which stands out for its simple interface and access to a wide range of streaming apps, including free movies, live TV, and popular channels, making it great for streaming fans and those who want a lot of entertainment options without extra cost.

With a 60 Hz refresh rate, the TV handles regular content smoothly, but it may not be the best choice if you are a fan of fast-paced sports or gaming where higher refresh rates can improve the viewing experience. It supports Dolby Audio and Bluetooth headphone mode, which enhances sound options, though built-in sound on TVs this size typically won't replace a dedicated sound system. Connectivity-wise, it includes Wi-Fi, Bluetooth, and USB ports, covering common connections for streaming and external devices.

The absence of HDR support means colors and contrast won’t be as vibrant or dynamic compared to TVs with HDR technology. The design is practical with a flat LED screen and a slim profile that fits well in most rooms. Viewing angles are standard for an LED TV, so the picture looks best when viewed straight on. This Roku TV suits viewers seeking a straightforward, budget-friendly smart TV experience with easy streaming access and decent picture quality at 1080p. For those wanting features like 4K resolution, HDR for richer visuals, or a higher refresh rate for smoother motion, other models may be more appropriate. However, for everyday use, especially in smaller rooms or bedrooms, it is a reliable and user-friendly option.
