[PConline Review] In recent years, although the prices of large-size TVs have been getting lower and lower, small-size products still account for more than half of the sales. To make steady gains, there is no way to imagine not using small-size products. Looking back at Lenovo’s product line, due to the short time to market, its product line is relatively narrow. At present, there are no 32-inch products in the two major series (high-end K series and main fashion S series). So Lenovo released a new series of A series products in June this year. The A series inherits the excellent smart UI and control design of the K and S series, and continues to carry dual-core dual GPU processors; in addition, the screen size extends to 42/ 32-inch, and expand the price of the product line to 1999 yuan, I believe this move will inevitably lead to the Lenovo TV's overall turnover.
Lenovo Smart TV 32A21 Picture Series Evaluation Forum Quote
So how about the performance of this cost-effective entry-level TV? Let's take a look at the detailed specifications of the product: The Lenovo smart TV A21 is equipped with a dual-core 1G dual-core dual GPU processor, built-in 4G storage capacity, and a custom Android 4.0 intelligent system.
â— Introduction of key functions
Lenovo A21 uses a dual-core 1Ghz CPU, we are currently unclear processor manufacturers, only know it is a dual-core CPU / GPU products, frequency 1GHz, run large games, download smart applications, play high-definition network video, can be completed very quickly .
A21 continues the good human-computer interaction experience before Lenovo smart TV. One-button VOD is the best expression. Lenovo currently cooperates with video licensee BesTV to provide 400,000 hours of massive video, TV drama, variety show, entertainment and sports videos. source. Claimed to be able to achieve playback and breakpoint playback within 3 seconds.
Multi-screen interaction is a key point in the future development of smart TVs. Even if it is an entry-level A21, Lenovo has equipped it with a built-in WiFi module and can realize the sharing and interaction functions of TV, tablet and mobile phone through wireless protocols.
In addition Lenovo A21 is also equipped with intelligent remote control and game controller, using the remote control 6-axis sensor to achieve more gaming experience. Let's take a look at the actual product.

A21's shape design is exactly the same as that of the S61, which is almost a smaller version of the S61, but the border and other parts of the process and design details are still slightly different.
From the aspect of size and material style, the A21 is not very eye-catching in design and craftsmanship, but because of this, the reduced cost of the A21 series can reduce the price even more.
The estimate is to further reduce costs. The manufacturer of A21 is a company owned by Lenovo. We searched the address from Google Maps and found that it was indeed Lenovo's own factory.
Interface configuration, although there is no audio fiber interface, but HDMI and USB interfaces are configured, the number is also two, I personally think that as a small-size TV, the daily use of the two interfaces is completely sufficient.
The buttons on the body are located on the left side of the TV. There are not many buttons, but the feel is very crisp.
The horn, as always, is located below the TV. The use of a ring diaphragm is a small-size speaker designed to fit the shape of the flat-panel TV as much as possible. I personally think that buying flat-panel TVs does not require too much attention to sound quality.
The remote control changes greatly. The K-Series touch + direction navigation area is split into arrow keys and touch bars, as well as a large number of function keys. The numeric keys are at the bottom.
Supporting the gamepad is also a major feature of the A21. There are also remote control keys on the side that can be held horizontally or vertically to simulate more somatosensory game forms, such as rackets.
Due to the fact that it is equipped with a borderless hard screen, polarized 3D (non-flash 3D) is conceivable. Since it does not require a power supply, it is much lighter than active shutter 3D glasses. A TV comes with a total of 3 pairs of glasses; one of them is a clip-on type that can be clipped to the glasses it wears. It is quite human.
â— Picture quality test
Quality testing parameters
First of all, we use the evaluation room professional instrument to conduct detailed tests on the Lenovo A21. In the test, we will adjust to the standard image mode, and the backlight is adjusted to the brightest. We first record the measured data in the following table.
After a professional color analyzer test, we obtained that the color saturation of A21 is equivalent to 72.53% of the NTSC color gamut. This data is a medium level in LCD TVs. The average brightness is 293.91 cd/m2. Both parameters are basically the same as those of the S61. It can be seen that although it is an entry-level product, there is no shrinkage in the basic quality parameters.
In terms of ANSI contrast, Lenovo's A21 performance is acceptable, and the 675.658:1 level is consistent with most entry-level models.
Under the black screen, A21 can control the light leakage phenomenon and it appears slightly bright in the four corners of the screen.
Grayscale, black bit real shot
Since the screen shot has undergone necessary software processing and is affected by the actual effects of the netizens' displays, the screen finally displayed on the screen will be different from the actual effect of the TV. Therefore, the actual effect is based on the author's text description. The author used a Hi-Definition Reference Disc to test the picture quality of the TV. (Because of the different effects of different display devices, you can refer to the editor's main view method when you cannot judge the screen shot.)
On the gray scale, the darkness of the A21's performance is slightly weaker, and the highlights can fully show their differences. However, the 0-2 color blocks cannot be easily distinguished.
There is also a good performance in latitude. The dark and bright parts of the tower can be displayed normally.
The details of the dark parts of the A21 are generally expressive, and the details of the darker parts of the charcoal can hardly be seen.
However, for the black display, its performance on the dark part will appear brighter, making it harder for the black to sink. This may be the commonality of the Lenovo S series and the A series.
High-speed dynamic screen real shot
In terms of dynamic high-speed performance, the performance of the A21 is not very good, but the overall performance is satisfactory. The outline of the locomotive is not very vague, and the scenery across the window is slightly blurred.
Color screen real shot
In the color reproduction please see the test dish real shot map.
Although there is still a certain reddish effect on the restoration of people's skin color, this level is relatively slight compared to many Korean products. In general, the color performance of A21 is relatively normal and accurate, and there will not be too much. More obvious rendering.
HD picture real shot
The actual high-definition video feedback information is similar to that of the test disc. The color reproduction is accurate and the saturation is not high. However, the natural rendering-free tendency of the author personally thinks that there is nothing wrong with it. This kind of processing is ultimately better than the transitional rendering. It's easier to accept.
HD static picture real shot
The static picture shows that the overall style of the picture is soft, the sharpness is not high, and the color saturation is normal.
â— Intelligent system trial
Humanized startup wizard
When the A21 is turned on for the first time, the TV will display the boot-up interface after the boot screen, which is displayed in the form of origami and is quite beautiful. In the setup, the product introduction video, network connection, and Lenovo user registration can be combined with Weibo and other accounts.
After completing the settings, the ideal TV's LOGO is displayed, along with other consumer electronics products, using the same idea label, indicating the continuity of Lenovo's products.
Sandwich User Interface
The user interface of the Lenovo smart TV is very simple. The user interface called "sandwich" is based on the depth customization of Android 4.0. The major feature is that the main interface has only three major sections: TV, online video, and application programs. Switch to select, and the animation transitions in practice are excellent.
Operation interface setting screen
The Lenovo A21 has a rich set of menus. Because of the depth-customized Android 4.03, it is not easy to notice the traces of Android in the settings menu. There are also certain options for adjusting the image and audio settings.
In addition, the network interface supports wired LAN and wireless Wifi in two forms. Lenovo A21 has a wealth of body settings options, including image, sound, network settings, application management and so on.
Online video resources
Lenovo and Shanghai Media Group have established a joint venture company, which makes online video resources abundant. The main program of the online video is directly on the “sandwich†interface. The subdivisions of Chinese movies and overseas movies can be directly selected. The top video preview section will play the recommended video resources cyclically. This part will be updated regularly. .
After entering the partition, you can slide through the remote touchpad. Film resources are quite abundant. According to the official, all video quality has reached the level of 480p and above, of which the level of 720p reaches 70% of all resources, of which more than 20% is ultra-clear resources with a resolution of 1080P.
In fact, the video resources are also quite abundant. The source of the videos watched by Xiao Bian basically reach the level of 720p. The ultra-clear video resources also have a good sense of the screen.
In the video resources, Xiao Bian also found that there are special paid areas, mainly new movies. These fine movies are between 3 yuan and 5 yuan. It can be seen that A21's online video resource management standards have reasonable charges. Interval.
Application resources
The application is also a separate page in the "sandwich interface". The upper part of the page is the application recommendations that are constantly switched; the lower part is the application shortcut. The overall operation is designed in terms of user-friendly considerations that are easy to understand and operate.
You can also click "Local apps" to browse all programs, you can quickly delete apps or set desktop shortcuts.
A21's built-in music store provides software downloads and upgrades. Currently, the number of software is quite large. Most of the commonly used software can be downloaded directly; some of them are customized by Lenovo, while others are used by Android tablets. Consistent.
Sina Weibo is a deeply customized software of Lenovo and its name has also been changed to Weibo TV. The program supports full HD resolution, and supports the operation of four-color shortcut keys on the remote control. No matter if it is forwarding, sending microblogs, @, etc.
The built-in browser also supports the operation of the air mouse. The speed of reading a web page is faster, and quick clicks, shortcut keys, and web pages can be switched.
Baidu maps are also customized software for Lenovo TVs. They can use remote control shortcuts to perform some functions and have high practicality in practical use.
Game resources trial play
One of the main features of the Lenovo smart TV is the game. Many of the games are customized by Lenovo. They can directly use the attached game controller to play games, including plant vs. zombies, badminton, tennis, and wild vehicles. It can be seen that Lenovo's relationship with other software developers is not normal. We can directly watch the game's trial video to learn more.
1. Plants vs Zombies
A21 directly built a plant vs. zombie game, this game is a customized version, not only the screen beyond the resolution of the general Andrews tablet, you must also try to use the game handle to operate, use the arrow keys or joystick to collect sunlight and planting plants Using the L and R keys to switch plant types is also faster. In addition to this game, there are fighting games, racing games and other customized games that need to use the handle directly to play. At this time, the 6-in-1 remote controller is disabled and can not be remotely controlled.
2, badminton (sense games)
This time, we specially selected a game that supports somatosensory, “badminton,†to try it out. In the game, you can use the grip to hold the game handle. When you swing, press the A button on the side of the handle to catch the ball.
In the game, you must swing the handle and press the A button at the same time to catch the ball. Although there is support for the body feeling, the amplitude of the action is not well recognized. Because the sense of the body is realized only by gravity sensing, it is not experienced. Wii infrared, Kinect motion detection and PS3 light detection.
3, Fruit Ninja (Air Mouse)
The above describes the experience of using gamepads or somatosensory games. What about games that are not specifically tailored for Lenovo? The answer is to use the 6-in-one remote control air mouse function, because the remote control supports 6-axis sensing, so you can achieve motion capture; air mouse appears as a cursor on the screen, press the OK key like a finger click on the touch screen to determine the general All touchscreen-based programs can rely on this method.
The remote air mouse function is sensitive to the detection of movements, but it is never as intuitive as playing games directly.
Lenovo smart TV's game features are more powerful, not only have many custom games, these custom games are better than the average Android game's screen, the compatibility of the game handle makes the experience to enhance significantly. Other non-customized Android games rely on the air mouse function to simulate the sense of touch, although the experience generally provides better compatibility.
USB streaming test
Lenovo A21 has 2 USB ports, which is quite a lot of flat-panel TVs. Due to the dual-core 1Ghz CPU and Android 4.0 system, we don't have to worry about its compatibility issues in high-definition video. After inserting the U disk, we can browse the files in the U disk directly in the system's own music, pictures, video software.
A21 has excellent compatibility with high-definition video formats. It can smoothly play the files of MOV, MP4, RMVB, MKV suffixes that have been tested by Xiaobian, and it also has the ability to load .SRT subtitle files, which can completely replace the use of high-definition players.
The music interface is relatively simple, you can directly read the cover of the music file, the operation is more smooth.
Among them, the compatibility of the picture format is good, and various operations can be performed.

Price analysis
In terms of positioning, the A21 series hits the entry-level market and is positioned lower than the K and S series. The main difference is in the remote control's remote control function, hardware configuration and operation, but the difference is not significant. The price of the current 32-inch A21 is at $1,999. It is priced similar to the mainstream 32-inch LCD TV. Although it is higher than the lowest price of the traditional TV on the market, its intelligent function is indeed far ahead of any rival in the industry.
to sum up
This is Lenovo's third wave of products to enter the smart TV market. After the continuation of the previous operation of the S61 sandwich system, it has reduced costs and selling prices. On the other hand, its smart features and image quality have been maintained. The level of first-class products, and still able to support a variety of applications and games, as an entry-level product, it has enough strength to compete with other TV manufacturers.
