Buying Guide For The Best Smart TV Under $400

When choosing a smart TV under a budget of 400 USD, you have to give certain factors the topmost priority. If done right, the chosen smart TV will not only come at an affordable price but will also offer the best features in the segment. To understand each of these factors, we advise you to go through this buying guide. It explains the relevant factors and helps you understand their relationship with a smart TV. Here’s a buying guide to help you choose the best smart TV under $400, going beyond the basics:

Screen Size and Resolution

  • 32-43 inches: Ideal for bedrooms, kitchens, or smaller living areas. A 32-inch TV is great for placing on a desk or countertop, while a 43-inch TV works well in a bedroom. Keep in mind that sitting distance also plays a role. For comfortable viewing of Full HD content, you want to be at least 1.5 times the screen size away from the TV.
  • 43-50 inches: A good mid-range size that works well in most living rooms, striking a balance between screen real estate and price.
  • 50 inches and above: Great for larger living rooms or home theaters, offering a more immersive viewing experience. However, these TVs tend to be heavier and require more space.


  • High Definition (720p): This is the most affordable option, but it won’t provide the sharpest picture quality. It’s suitable for watching casual content or using the TV as a secondary display. However, with the rise of streaming services offering high-quality content, even budget-conscious users might want to consider a higher resolution.
  • Full HD (1080p): The most common resolution for TVs under $400. It offers a good balance of price and picture quality, and you’ll find a wide selection of content available in 1080p.
  • Ultra HD (4K): Offers the sharpest picture quality, with four times the resolution of Full HD. However, 4K content can be more expensive to stream, and you’ll need a fast and reliable internet connection to enjoy it. If you plan on watching a lot of 4K content or are a gamer, then a 4K TV is a good option. However, if you’re on a tight budget and don’t mind a slightly less sharp picture, then a 1080p TV is a perfectly reasonable choice.

Smart Features

  • Smart platform: Most smart TVs under $400 will come with a built-in smart platform, such as Roku, Fire TV, or Google TV. This platform allows you to stream movies, TV shows, and music from a variety of apps. Roku is known for its user-friendly interface, Fire TV integrates well with Amazon’s ecosystem, and Google TV offers a personalized experience with Google Assistant integration.
  • Apps: Consider which apps are important to you and make sure the smart TV you choose supports them. Popular options include Netflix, Hulu, Disney+, YouTube, and HBO Max. You can usually find a list of supported apps on the manufacturer’s website.
  • Voice control: Some smart TVs also support voice control, which allows you to control the TV with your voice. This can be a handy feature, especially if you’re using the TV to stream content or control smart home devices.

Other Features to Consider

  • HDR: High Dynamic Range (HDR) TVs offer a wider range of colors and contrast than standard TVs, resulting in a more realistic and immersive viewing experience. However, HDR content can be more expensive to stream and not all TVs under $400 support HDR. If you plan on watching a lot of HDR content, look for a TV with HDR10 or Dolby Vision compatibility.
  • Refresh rate: The refresh rate determines how often the image on the screen is updated. A higher refresh rate is better for watching fast-paced content, such as sports or action movies, as it reduces blur and judder. Most TVs under $400 will have a refresh rate of 60Hz, which is fine for most casual viewers. If you’re a gamer or cinephile, you might want to consider a TV with a 120Hz refresh rate for smoother motion.
  • Ports: Make sure the TV has the ports you need to connect your devices, such as HDMI, USB, and optical audio. HDMI ports are essential for connecting streaming devices, gaming consoles, and cable/satellite boxes. USB ports allow you to connect external storage devices, such as flash drives and hard drives, to play back your own media. An optical audio port is useful for connecting the TV to a soundbar or home theater system.
