Ranked in these QuestionsQuestion Ranking
Pro Works well as a computer monitor
This 4K TV has everything a good computer monitor needs. It has small input lag, barely noticeable motion blur, decent color accuracy, and full 4:4:4 color support.
As for responsiveness, the TCL S405 is the fastest TV in its price range. It has the lowest input lag (14.9 ms) among all of its main competitors, including the Sony X720E and Samsung MU6300.
Furthermore, the S405 is handling motion blur excellently because of its fast full response time. The full response time of the TCL S405 is 14.4 ms which means that the TV’s pixels can entirely change their colors in 14.4 ms - ten times faster than an average blink. Because of that, fast-moving objects don’t leave trails; thus the TV does not suffer from any noticeable motion blur.
Pro Reasonable picture quality
When placed in a dark environment, the S405 can reproduce decent picture quality as the TV's VA panel has a reasonably high native contrast ratio (4171:1), acceptable grey uniformity, excellent black uniformity, and good color accuracy. Regarding the overall image quality, the S405 is on a par with its competitors like the Sony X720E.
Pro Excellent value for money
Priced below $300 (43-inch model), this 4K TV has enough functionality to compete against more expensive competitors. You’d be hard pressed to find a similar TV in its price range due to its decent picture quality and broad feature set.
Pro Ads-free interface
The main interface of this TV does not have advertisements. It even has a function to limit ads even in third-party applications.
Pro Displays colors accurately
Out of the box, the TLC S405 does an excellent job of color reproduction. In fact, you probably won’t even need to calibrate it.
Pro Can be used up-front
Because of its reasonably small panel size, you can place the 43-inch model of the TCL S405 on top of your work desk and use it as a computer monitor. This is possible because of its small minimum viewing distance (2.2 ft).
Pro Intuitive user interface
The S405 runs the Roku TV smart OS platform. The platform has noticeably simpler navigation than Android TV, WebOS, and Tizen. Furthermore, the Roku TV does not lack functionality because of its broad app support.
Pro Good for sports
Due to the TV’s fast response time, the S405 is also an excellent solution for those who like to watch highly dynamic content, such as sports. The 4/5 response time (the parameter which describes how good a TV handles motion blur) of this TV is 6.3 ms. That is a much better response time than some higher-end competitors can offer. In fact, its closest competitors: the VIZIO E-series, Sony X720E, and Samsung MU6300 have worse motion blur handling capabilities than the S405.
Pro Good for gaming
This TV is an excellent choice for gaming because of its low input lag, well-handled motion blur, and full HDR support. It works well with every new-gen console like the Xbox One X and PS4 Pro because of the TV’s native 4K60 refresh rate. Furthermore, the TV’s low HDR input lag makes it an ideal solution for HDR gaming.
Con Narrow viewing angle
Due to its limited viewing angle, the TCL S405 looks good only when you sit right in front of it. This viewing angle limitation is very common among VA panels, making such TVs not suitable for group watching.
Con Not all HDR formats are supported
This TV is compatible with HDR10, but not with Dolby Vision content. While HDR10 has more content, Dolby is aggressively pushing Dolby Vision towards content makers.
Con Not suitable for bright rooms
This TV is not bright enough to fight glare when placed in a luminous environment.
Con Remote lacks functionality
The TCL S405's remote is very basic and has limited functionality. It can only be used for navigation and sound level control, which is not that much since many modern TV remotes have advanced functions.
Con Poor sound quality
The stereo speaker system sounds horrible and cannot get louder than 91 dB. Adding a relatively cheap speaker system or a soundbar will make a huge difference.
