TCL is a Chinese international company that produces mostly TVs and other home appliances. This award-winning company has been recommended by many professional reviewers and editors, including being awarded the 2017 Gold Stevie for customer service.

While most TCL TVs can’t compare directly with other brands in terms of overall build quality, these TVs are generally priced very affordably. TCL is a great brand for budget-friendly TVs of all sizes. Because TCL TVs range from 32 inches to 75 inches, the S405 is a mid-sized smart TV that is perfect for your living room entertainment system.

TCL offers plenty of TV options, which makes it easy to find other models if you feel the S405 is too expensive or too small for your needs. While a 55-inch TV is a popular size for a living room entertainment system, some people prefer larger or smaller, depending on the size of your room.

Why Choose a Smart TV?

If your house is already full of smart devices and computer screens in every room, it may seem difficult to choose a smart TV. In order to determine whether a smart TV is the right option for you, here are some popular features of a smart TV.

Stream content

By far the most useful tool of a smart TV is online streaming. You can easily connect your smart TV to the internet and watch TV shows and movies without having to connect another device. It’s the best way to find an endless amount of your favorite shows, videos, and movies. Roku TV, the smart TV software for all TCL smart TVs, offers easy-to-use menus to find your favorite online streaming app. Whether you watch shows on Netflix, Hulu, Amazon Prime or through another popular service, you’ll be able to easily connect your account to your Roku smart TV.

Surf the Web

While you are waiting for the next season of your favorite show to come out, check out your social media sites and shop online with your TCL smart TV. While the Roku remote has too few buttons to make this feature convenient, you can easily use the app to turn your tablet or smartphone into a high-tech remote with a full keyboard and other handy features.

Up-to-Date Apps

While smart TV apps may not be as convenient or plentiful as smartphone apps, there are still plenty of options to choose from. Most smart TV apps work just like additional channels on a traditional TV. There are a few time-saving and convenience apps available as well, like a calendar, news stations, and even instant football stats. This is one of the most noticeable differences between smart TV software, so compare the relatively small Roku app list with more popular options, like the Samsung smart TV, to see what apps will be most useful for you.

From the large screen to the impressive price tag, the TCL S405 TV is a great option for a budget-friendly living room. For a 55-inch TV, it’s recommended that you sit between 6 and 11 feet away from the screen. This will allow you to get the most out of the size of your TV. If your room can’t accommodate this viewing distance, consider choosing another smart TV for your room. While 55 inches is mid-range for current models of TVs, many customers report that this TV feels impressively large for their living room.

Roku Smart TV


The surprisingly simple remote of the S405 is paired with a comprehensive menu that is intuitive and offers plenty of smart capabilities. Use the Roku app to access voice control with your smart device or use your smartphone’s headphones to listen to your TV in private. From streaming online content to surfing the web, smart TVs have plenty of features and capabilities that make them far more than a TV-show-watching machine.

However, a useful feature of smart TVs is the ability to sync with other smart devices in your home. While this TV syncs easily with your smartphone or tablet, it may not be as convenient as other TVs. If you love a convenient, stress-free connection between all your devices, more popular brands, like Samsung, offer a more intuitive connection between multiple devices.

Resolution and Refresh Rate

Numbers don’t lie. While the TCL may cost less and use lower quality parts, the screen resolution and refresh rate are just as high as premium 55-inch TVs. Whether you are playing video games, streaming your favorite movies, or binge-watching the latest TV shows, you’ll enjoy some of the best resolution and refresh rates on the market. TVs have either a refresh rate of 60 Hz or 120 Hz. Most films and TV shows are filmed in 60 Hz, so a refresh rate of 120 Hz doubles the number of frames. This is particularly important for fast-paced scenes, where a refresh rate of 60 Hz may appear sluggish or slightly blurry. Premium TVs come standard with a refresh rate of 120 Hz, just like the TCL S405.


The TCL S405 comes with Dolby Digital Plus audio, but most customers and reviewers agree that the sound quality is less-than-optimal. While the speakers are functional, you might want to consider purchasing separate speakers or a sound bar in order to match the sound quality of premium high-definition TVs. However, many customers have this same issue with competitor’s TVs as well, so this is more of an industry problem than an issue with the TCL S405.


At 30 pounds and only 3 inches thick, the TCL S405 is a comparable weight and slightly thinner than other 55-inch TVs. The true display size is only 54.6 inches, which is typical of TVs claiming to be 55 inches. The S405 comes with a stand, but consider purchasing a wall mount for this large TV. Many customers who hadn’t purchased a large TV before were surprised at the size difference when compared to older TVs.


Few 4K ultra-high-definition TVs can compare with the TCL S405. With similar specifications, most competitors cost over $100 more than this budget-friendly option. While the MSRP for the TCL S405 is $499.99, most department stores sell the S405 for $379.99. Check out online stores for the best deals. Other 55-inch smart TVs can cost between $499.99 or more. Some of the most premium 55-inch TVs, like a Sony model, can be over $1,200.00. Carefully consider your budget, as well as the features that are most important to you.

Like most TV brands, TCL makes a similar model at a variety of screen sizes. If this 55-inch TV is too expensive or too small for you, consider an option with a 43-inch, 49-inch, or 65-inch display. Because of the poor speaker quality, you may want to consider adding a speaker bar or other sound system to your budget as well.

The TCL S405 is a popular model in the 4 Series, so you can find it at a variety of locations. Check out online stores, like Best Buy and Amazon, or visit a local electronics store to compare different models and prices. Many online stores offer free delivery with a large purchase like a TV, so be sure to order from a company that offers free delivery.

The mid-range model in an impressively large line of TVs, this LG TV can range from 43 inches to 77 inches. The LG 55-inch TV has all the basic specifications of the TCL S405, but also includes voice controls. Speak directly to your TV with Google Assistant, or connect with Amazon Alexa for convenient controls and easy commands.

Just like the Samsung NU7100, the LG UK6300 includes three HDMI ports, which is more than the TCL S405. This is particularly important for gamers who want to connect multiple gaming systems easily.

Just like the other TVs on this list, the LG option comes with a one-year limited warranty on labor and parts. Customers love the display and smart capabilities of this TV, as well as the easy set-up. However, many customers reported the stand breaks easily. While it comes with a TV stand, you should consider using a wall-mount in order to protect your TV and ensure the stand won’t be damaged. Customers also dislike the sound quality of this TV, which is typical of TVs at this price range. If you want a mid-priced, 55-inch TV with voice-activated controls, this is a great option for you.

While most of the specifications may appear similar, Samsung TVs are typically far more expensive and made from more durable materials. This Samsung model includes 3 HDMI ports, just like the LG UK6300. The resolution and refresh rate are the same as both the TCL and LG models, which means this TV costs much more for a similar product.

However, most customers prefer Samsung’s smart TV software instead of competitors, like Roku. Just like others, this TV series comes in a wide range of screen sizes. Choose one of the 8 sizes between 40 inches and 75 inches for a custom-fit TV for your living room, bedroom or anywhere else you choose. This premium TV comes with a one-year warranty and is able to be mounted on the wall or used with a TV stand. While it’s an affordable option for Samsung, it’s one of the more expensive 55-inch options you can choose. Consider this TV if you want a reliable brand with excellent smart features.

Pros and Cons of the TCL S405

The TCL S405 isn’t the most affordable TV on the market, but it is far less expensive than other brands that feature comparable specifications. Consider the pros and cons of the TCL S405 and other 55-inch smart TVs. Only you can determine which TV is the best option for your home and your lifestyle. You want to choose a TV that not only matches your budget, but will also work with your entire entertainment system.


  • Affordable price
  • Simple remote and smart features
  • High resolution


  • Smart TV not as intuitive as competitors
  • Only two HDMI ports


These days, a 55-inch TV is a mid-sized option. If you are up-to-date with the latest TVs, you may consider this TV for a secondary screen or a bedroom option. If, on the other hand, you haven’t bought a TV in a while, you’ll be impressed with the large size and excellent resolution of this 2017 TV. Choose the TCL S405 if you want an affordable option that boasts a high-tech menu and connectivity with all your computer devices. Consider an alternative option if you need more HDMI ports, a more premium brand, or a more popular smart TV menu.
