How about Lenovo 17TV? good or not? Deep experience comprehensive evaluation
Last month, Lenovo announced the launch of its Internet TV brand "17TV". The higher price/performance ratio and various features and services have led to a renewed battle in the current TV industry. As the 17TV's first hardware product, how does the 55S9i perform?
Exterior
The appearance of the 55S9i bid farewell to the traditional black, the main body uses champagne gold. It also uses the current ultra-narrow frame design, the border is only 5.9mm, and the front frame also uses a black design, from the front will basically not notice the frame.
The back body is made of a light-coloured cloth textured plastic design that can tolerate dirt to a certain extent and feels good. The fuselage is designed with hidden vents and screws and looks very refined. Officially provided with self-installed bases and hanging holes, you can choose to place on the table or hung on the wall.
The interface 55S9i is equipped with a very complete, including: USB 2.0, USB 3.0, HDMI 1.4, HDMI 2.0, SD card slot, component / video input interface, headphones, cable TV interface, network port and maintenance of a dedicated interface.
screen
As a TV, the most important part is the screen, let's talk about the screen part.
17TV uses a 55-inch 4K resolution screen that supports 3D. The screen refresh rate is up to 120Hz in 3D and up to 60Hz in 2D. The contrast is 8000:1.
Before I got the real machine, I saw a serious post that leaked. Let's look at the pictures I took first.
Has it been intimidated by this leak? Don't worry, let's talk about what is light leakage.
17TV uses the ADS screen, also known as the iFFS screen, and the IPS is a hard screen, which is the use of horizontally arranged night view fan structure. Compared with IPS ADS, ITO transparent electrodes are used in place of metal electrodes, which increases the aperture ratio and light transmittance of the screen, which means better color performance. However, such a horizontally arranged liquid crystal molecular structure cannot be changed by a relative VA soft screen, and the light transmittance is still lower, so an LED backlight with stronger light is required. Therefore, the performance of light leakage will be relatively weaker.
The night scene itself is not light, and the need for backlighting is well known. However, the larger the screen, the harder it is to control the flatness of the reflective film, the light guide plate, and the diffusion film, thereby affecting the uniformity of the backlight. Secondly, the LED itself will generate heat, which will cause the reflective film to be thermally deformed, which will also affect the backlight. Extremely slight errors in the components of the final assembly can also affect the backlight.
Saying the photo I just took just looks scary, but the naked eye is not as serious.
The results obtained with different camera parameters, including different apertures, different ISO, different shutter times, are also different. Even when shooting with a mobile phone, different shooting modes have different effects. For example, the following figure is what I found on the Internet. The shooting content was taken under different conditions using different camera parameters.
Based on the above reasons, this LCD screen perfect screen basically does not exist, not the best is better. No matter which brand is the same, you can find a bunch of search results in Baidu search for “any brand + light leakageâ€.
17TV official said that for light leakage, the national standard requires ≤ 4cd/m2 (less than or equal to 4 candelas per square meter), they use 2% ND filter + production line dark room 100% pure black screen detection method, standard ≤ 1cd/m2 .
In fact, although this TV leak situation has appeared, it is also within the scope of acceptance. I saw many people on the Internet watching the TV leak when they deliberately closed the curtains at night and watched it. In fact, this was a bit nitpicking. Because the brightness of the TV is very high, watching the TV at night to turn on the interior lights can avoid the irritation of the eyes caused by strong light.
In summary, light leakage on the screen does not affect normal use. After all, not every day you have to watch a horror movie with your sister turning off the lights. If you really feel that the problem of TV leakage in your hands is unacceptable, 17TV's after-sales service is still relatively awesome, with 30 days refunding, and 365 days only for repairs.
Other hardware
In addition to the screen, the 17TV uses JBL speakers to support Dolby sound. In actual experience, although the audio effects can not be compared with professional audio equipment, the experience is still good.
17TV also uses MTK dual-core 1.2GHZ A17 architecture processor, support H.265 encoding format. It also uses the popular Mali 450 processor at this price point. It also comes with 2GB of memory and 8GB of storage, and the actual user space is about 4GB.
17TV also supports Bluetooth 4.0 and 802.11ac WiFi protocols, using MIMO dual antennas.
Remote control 17TV uses voice-activated air rats at this price is very rare. It has a built-in gyroscope and gravity sensor, and is connected to a TV via Bluetooth. The accuracy is also very good. Ergonomically designed hand grip is also very comfortable.
system software
After finishing the hardware, we came to talk about the software. The 17TV is still equipped with Lenovo's Ali YUN OS and Sandwich UI, making it very smooth.
However, what is interesting is that I used several software tests and the results showed that this TV has a resolution of 1920x1080, which means that Full HD is not 4K.
After testing, the resolution of the 17TV's own UI is 1080P, but it can be seen from the external signal input of HDMI 2.0. In terms of this screen, it is indeed a 4K resolution of 3840x2160 at the physical level.
After asking the official, 17TV native UI is indeed 1080P, but the system has 4K decoding function, when playing 4K video will be 4K but presented.
In fact, this problem can be considered a small secret of the industry. Many brands of 4K TVs use 1080PUI. However, this problem is not so important in use. As far as cable television is concerned, the HD resolution is only 1080p. The number of dedicated 4K sources is very small, and the broadband bandwidth of the average household may not be able to bear. If the system UI is directly set to the 4K level, it would be too difficult for the current processor to achieve the current fluency.
Another reason for using 1080P is software compatibility issues. If you directly set the UI to 4K, many software problems will occur.
17TV also added a variety of image processing engines for image quality, including the following:
Sharp sharp MEMC motion image processing technology: Through backlight scanning, panel driver interpolation frame, effectively alleviate the tailing phenomenon, clear reproduction of fast motion scenes.
Sharp sharp image sharpening technology: Reduces ghosting and enhances edge details through Chiap processor's tap-adaptive and comb filter Improvement algorithms; reduces noise through De-blocking algorithm and brings super clear visual enjoyment.
Sharp sharp color processing technology: Through the 3D Color Engine algorithm, the colors are more beautiful, the details are clearer, the levels are clearer, and the color transition is more natural.
Sharp sharp contrast processing technology: Through the adative luma algorithm, enhance the contrast and make the picture more translucent.
For general source and Full HD HD source, the display effect is still good.
If you still don't believe that this panel supports 4K resolution, please plug your computer host into the test. It should be reminded that if the graphics card supports GTX 960 and above, it can support HDMI 2.0 graphics cards.
The sandwich user interface divides the TV interface into three screens: signal input, syndicated content, and application games.
The 17TV supports the voice control of "thinking girl" and can use the remote controller to directly play the desired content with voice. If there is only one video in the search results, it will play directly. And the recognition rate of speech is still relatively high. "Thinking of the girl" also adds a title correction function to make speech recognition more accurate. Of course, you can open the application directly by voice.
One of the more interesting features is the music lock, which allows the TV remote control to control the set-top box swapping without pairing learning, which means you can completely get rid of the trouble of multiple remote controls.
Content service
A major feature of 17TV is his content aggregation service. This screen aggregates legitimate sources including a variety of content providers such as Best Connect, iQiyi, Sohu, and Ali. Mainstream domestic and foreign films, TV shows, and variety shows are all captured, but most of the new movies require a $5 purchase. Fortunately, 17TV comes with a package season card, you can first experience.
In addition, you can also buy Premier League, NBA and other content directly on the TV, watch the game the first time.
In addition to its rich source, the 17TV also supports a feature called "0 seconds to start broadcasting." In the case of bandwidth, it can achieve a video-playing experience by preloading. At the same time also supports the suspension of the cache, to the beginning and end of the film, breakpoints continued transmission, stream adaptation and other functions. It is a feature that many Internet TV stations are still incomplete.
Software applications, 17TV built-in Lenovo Music Store, mainstream application games it is compatible. Including a variety of players, news reading software, somatosensory games, popular mobile games and so on.
Beyond the first time, you can also bind WeChat or install a "TV-controlled" collaboration app to control the TV via the phone, or to install applications or play content on the TV.
In addition, it is also mentioned that 17TV has reached cooperation with Chunyu family doctors. The built-in application can realize the functions of consulting doctors, self-examination of symptoms, and nearby hospitals/drug stores, etc., which are very convenient to use.
The TV can also be installed directly in the store "anger birds" "ski adventure" "cut fruit" or even "Fantasy Westward Journey" "Boxing 97" "Riptide Speed ​​Boat 2" and other games. Some support air rat, some support sense still have some support handles, it is very comprehensive for ordinary leisure. Like my parents, when I was older, I had to fight for landlords. It is not good for people to have eyes on the eyes, and it is even more unfavorable for eye care to keep a mobile phone every day. Now they can sit directly on the TV and landlords.
If the content in the store still cannot meet you, then I can only say that this is a TV based on Android, so everyone knows.
Features: Tiger Mode
This is a special area designed specifically for kids. After entering this mode, the TV will automatically make the following adjustments:
Decrease Blu-ray: Blue light will have an effect on the macular area of ​​the child's retina. For a long time, watching TV with strong blue light will hinder the visual development of children. After entering the Tiger Mode, the 17TV will filter the blue light while lowering the screen's color temperature and brightness, thereby eliminating the impact on the human voice.
Elimination of flicker: Significantly increase the backlight drive frequency to eliminate flicker without affecting product life.
Adjust the screen brightness: Adjust the screen brightness to the most comfortable viewing experience for your eyes.
In addition to the above adjustments on the hardware, the Tiger Mode can also give advice on how to watch TV for different ages. It will automatically stop playing or even shut down at the time.
However, in the trial, it was found that the existence of the contents of the Beidou Shen Quan in the tiger and mother mode did not seem to be suitable for children to watch. After inquiring official officials, as there is no classification system for animation content in China, it is now determined whether the standard, that is, whether the content has been broadcast on television. In addition to the relevant standards, content operations will also listen to feedback from users on the Internet and TV parents in a timely manner, and gradually eliminate some of the cartoons that do not meet the mainstream awareness from children's categories.
The contents of the Tiger Mode are selected for children to watch. If you are unwilling to give the child individual content, you can also manually filter it out.
However, although there is a setting for different children in the Tiger Mode, it is only the duration control. Looking forward to the next version of the software update can make a more detailed classification of the content.
to sum up
Lenovo’s 17TV brand is intended to compete with emerging Internet TVs such as Xiaomi and LeTV. In addition to using high-end configuration and low prices, 17TV recently made breakthroughs in copywriting and other aspects.
However, from the perspective of a user, no one will care about your blows, we just want a good product. In this era of frustration, the wine is also afraid of the deep alley.
Only this product, I saw the sincerity of 17TV, 3999 yuan to buy 55-inch 4K and even empty remote control, cost is not bad. Although there is room for improvement in software, the current experience is not bad. It is hoped that 17TV will really be a transformation of Lenovo's TV and not a change of consumers.
