10 Best 40 Inch Smart Tvs 2026 in the United States

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.

The LG 42-Inch OLED evo AI 4K C5 Series Smart TV offers an impressive viewing experience thanks to its OLED display, which delivers perfect blacks and vibrant colors by controlling each pixel individually. With a 4K resolution and support for Dolby Vision and HDR10, the picture quality is sharp and bright, making movies and shows look stunning. The TV’s 120Hz refresh rate ensures smooth motion, which is great for fast scenes in sports or gaming, although some gamers might wish for a full 144Hz. It also features low response times and advanced gaming tech like NVIDIA G-Sync and AMD FreeSync, making it a strong choice for gaming enthusiasts.

Sound is enhanced by Dolby Atmos and LG's Wow Orchestra technology, providing immersive audio without needing extra speakers. The built-in Alpha 9 AI processor boosts picture and sound quality, adapting to what you watch, which is helpful if you're not keen on manual settings. Its smart platform, webOS, is user-friendly and offers many streaming apps plus handy voice assistants like Alexa built-in. Connectivity options are solid with multiple HDMI 2.1 ports, USB, Bluetooth, and Wi-Fi, supporting various devices easily.

The design is sleek and modern, fitting well in a living room, and the 42-inch size is good for medium-sized spaces, although slightly bigger sizes might suit larger rooms better. A minor consideration is that the TV is priced towards the upper mid-range, so it might be a bit expensive for budget shoppers. This LG model is well suited for someone wanting excellent picture and sound quality, smart features, and a good gaming experience in a compact 42-inch OLED screen.

The TCL 43-Inch Class S5 UHD 4K LED Smart TV with Fire TV (43S551F, 2024 Model) offers a lot of impressive features for its category. The 4K UltraHD resolution provides stunning detail, which is four times the resolution of 1080p Full HDTVs. It also boasts HDR PRO+ with Dolby Vision, HDR10+, HDR10, and HLG, ensuring enhanced contrast and vibrant colors, making your viewing experience more realistic and immersive. The Fire TV platform is a great addition, giving you access to a vast array of streaming services and live TV, all in one place.

Alexa built-in with voice remote makes navigation and control easy, adding to the convenience. The TV also supports Apple AirPlay 2, which is a nice touch for iOS users. For gamers, the Auto Game Mode (ALLM) minimizes input lag for smoother gameplay. On the audio side, it features Dolby Atmos and DTS Virtual:X for a more immersive sound experience, and an Enhanced Dialogue Mode for clearer audio in movies and shows. The design is sleek with a bezel-less look, making it a stylish addition to any room.

However, there are a few drawbacks. The refresh rate is only 60 Hz, which might not be ideal for those who prioritize super-smooth motion, especially in fast-paced action scenes or sports. Additionally, while the built-in speakers are decent, they might not satisfy audiophiles or those looking for a more powerful sound system. Lastly, although the viewing angles are generally good, there may be some color distortion when viewed from extreme angles. This TV is a strong contender in the 40-inch smart TV category, especially for those who enjoy streaming, gaming, and smart home integration, but may fall short for those seeking top-tier refresh rates and audio performance.
