10 Best 40 Inch Smart Tvs 2025 in the United States

The INSIGNIA 40" Class F40 Series Fire TV offers a solid 1080p Full HD resolution, which is great for clear and sharp picture quality on a 40-inch screen, making it suitable for everyday TV watching and casual gaming. It runs on the Fire TV smart platform, giving you access to popular streaming services like Netflix, Prime Video, and Disney+, all navigable with the convenient Alexa Voice Remote for easy voice commands. The TV has a standard 60 Hz refresh rate, which works fine for most shows and movies but might not be ideal for fast-paced gaming or sports where smoother motion is preferred. While it supports DTS Virtual-X sound technology for an immersive audio experience, the built-in speakers can still feel a bit limited compared to separate sound systems.

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.

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.
