10 Best 40 Inch Smart Tvs 2025 in the United States

The Roku Smart TV – 40-Inch Select Series offers a great combination of features and affordability, making it an appealing choice for those looking for a good streaming experience. With its 1080p Full HD resolution, it delivers clear and sharp picture quality, sufficient for most users who watch TV shows, movies, and sports. The LED display technology ensures bright and vibrant images, while the 60 Hz refresh rate is adequate for smooth playback of regular TV content, though it may not be ideal for fast-paced gaming.

The built-in Roku platform is a major highlight, providing easy and fast access to a wide range of streaming apps and channels, including a substantial amount of free content. The customizable home screen allows for a personalized viewing experience, which is user-friendly and convenient. The Roku Voice Remote adds to the ease of use, allowing for voice commands to search and control the TV.

However, the TV falls short in a couple of areas. The audio quality, while designed for clear speech, may not be as robust as some higher-end models, potentially requiring a soundbar for a better audio experience. Additionally, the connectivity options like Wi-Fi, USB, and HDMI are standard but might not be sufficient for users with multiple devices to connect. The design is simple and functional, though not particularly premium, making it blend in rather than stand out in most room settings. This TV is best suited for individuals or families seeking an affordable, user-friendly smart TV with a good range of streaming options and decent picture quality.

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 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.
