Having rapidly evolved, smart TVs no longer hold the title of “idiot box”. The current generation of smart TVs comes equipped with a long list of features like internet connectivity, app compatibility, operating systems, and many more. With these features, the viewing experience has also improved a lot. Thanks to the aggressive competition between brands, smart TVs are now available for under $400.

The Smart TVs under $400 may be budget-oriented units, but they do not compromise with a user’s viewing experience.

We have explained some of the features below to give you an idea about their importance.

  • Screen Resolution: Screen resolution is considered an important factor for a smart TV. It refers to the overall quantity of pixels (both horizontal and vertical) present on the screen. A higher resolution improves the quality of the content displayed on the smart TV screen. Smart TVs under the $400 range usually feature screen resolution from 720p to over 4K.
  • Display Size: A smart TV must feature a suitable display size to deliver a comfortable viewing angle to the user. The screen size helps users in engaging with the content, thereby improving the immersion level. If the display size is too large or small, the viewing experience will not be good for the user. Under the 400 USD price range, brands offer display sizes between 40 inches to 65 inches.
  • Display Technology: The display technology used by a smart TV matters for various reasons. It has to produce correct levels of brightness, contrast, saturation, etc. At the same time, display technology must be energy efficient. The viewing angle is also an important sub-factor of display technology. Majority of the smart TVs have adopted LED display technology while some units feature older LCD technology.

When these factors are given importance, users can sort out the best smart TV amongst several options. Since smart TVs are being accepted by a large portion of consumers, the market is already flooded with several options.

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.

1. Screen Resolution

Screen resolution as a major factor controls other factors like screen size, refresh rate, etc. Without good resolution, high-quality content will appear degraded. The terms refer to the total number of pixels contained by a screen, including horizontal and vertical ones. Looking at the TV screen closely, the pixels become visible to the human eye. Since the high density of pixels together creates a recognizable image or video, the resolution must be high for smart TVs. A higher resolution also means the TV will display an equivalent quality of output. Almost every smart TV below $400 features 4K resolution and comfortably displays 4K quality media.

2. Display Size

You might get a high-resolution smart TV but if the display size is smaller, the user will not be able to approve the content’s quality. The viewing distance is taken into consideration for any type of TV while selecting its screen size. A larger screen offers more area to display the content thereby improving the viewing experience. The diagonal length between opposite corners of the smart TV is referred to as screen or display size. Under the $400 price range, users easily get smart TVs with display sizes ranging from 40 inches to 65 inches. A larger screen size is preferred by consumers but requires more space for installation.

3. Display Technology

Display technology plays an important role in the design of a smart TV. The older generations of televisions were based on cathode ray tube (CRT) technology, making them bulkier. A slim design for smart TVs was achieved by using newer technologies like liquid crystal display (LCD). Replacing the bulky vacuum tube in CRT, LCD TVs feature several layers of filters. The current generation of smart TVs runs on LED technology which offers better sharpness, congrats, brightness, saturation, etc. in the displayed content. Since these TVs use LED emitters, their thickness is much less than TVs using other display technologies.

4. Smart Apps

A smart TV will be of no use if it does not support the installation of several apps. These units run on various operating systems like Android TV, WebOS, etc. Various brands develop dedicated applications for these operating systems to help the user install apps on the smart TV. The smart apps offer on-demand entertainment, games, additional functions, and many other features. Users can access these apps via a dedicated app store and install them on the built-in storage of the smart TVs. Users must check if the app is compatible with the TV’s operating system. Due to limited storage space on smart TVs, app size is also given equal importance.

5. Refresh Rate

The refresh rate has become a synonymous term for smart TVs in recent years. In simple words, the refresh rate tells us how many frames will be refreshed on the screen within a second. The refresh rate becomes noticeable when video is played on the TV screen. Human eyes have adapted to the refresh rate between 30 to 60 Hz. A refresh rate above 60 Hz turns the video smooth and reduces the blurring of the video. Smart TVs with a refresh rate ranging between 120Hz to 240Hz are available depending on the user’s preference. TVs with refresh rates beyond this range use image processing to boost video frames.

6. Warranty

Even if you are buying a smart TV in the $400 range, it is still an important investment. Any type of damage poses a risk of losing the functionality of your smart TV. Besides this, repairs or replacements will empty your pockets. To avoid such situations, the smart TVs come with warranty coverage. It guarantees the user with free repairs and replacements of their smart TVs till a specified time. Smart TVs below $400 price come with a minimum warranty of 1 year. Some brands also offer extended warranties of up to 4 years on selective models. The terms for warranty vary from brand to brand and hence users must check them beforehand.
