The author has evaluated the representative models of five TV brands from last year to this year, and the performance of LCD TVs is very well known. This is also a great honor to get the experience of Changhong 55D2P all-metal HDR artificial intelligence TV provided by Suning evaluation, so that I can feel Changhong's charm of this HDR Ultra HD LCD TV. Let's take this TV as an example to see what considerations should be taken in choosing a living room TV.
Out of the box
Changhong TV brand is the old brand in domestic TV. When I was a child, I watched Changhong. I didn't expect children to go to school. Changhong TV is still strong. Facing the emergence of Internet TV brands, Changhong has also introduced LED intelligent 4K TVs with the times. The 55D2P is one of the explosive models. As soon as she entered the door, she noticed that the packaging was solid and had four wraps fixed. After opening, it was found that in addition to foam fixing around, there was a row of inflatable bags on the side of the panel. Take out the accessories, and see that there are two metal brackets, a pair of 7th battery, a remote control, 4 fixed screws, a warranty card and a manual, I saw the USB that is not often seen in other brands of TV Extension line, presumably to allow users to connect U disk and other devices more convenient, people-oriented or very intimate.
With the CHiQ artificial intelligence client, Changhong 55D2P all-metal HDR artificial intelligence TV can realize artificial intelligence voice control: for example: voice to say the name of the movie to play, how many seconds to advance to a fast, the sound to adjust the size, etc., can also let her recommend 4K Movies, broadcast weather, stocks, and more. Using the system's own screen-casting function, pictures, music, video, and even games on the mobile phone can be delivered to the TV screen, enabling the function of playing music, video, and pictures. Are you looking forward to this TV?
installation
Currently, there are two ways to install the TV. One is to use the bracket to mount it on the TV cabinet, and the other is to use the wall bracket to hang the TV on the wall. If you choose to wall-hang, the master who needs delivery will use a tool to measure the hole in the wall to install. If you choose the bracket, you can install it like I do. The appearance of the metal bracket is treated with an anodizing process consistent with the frame of the fuselage, and the texture of the touch is good. The brackets are divided into two groups, so it is impossible to install the wrong ones. Because the wrong ones cannot be inserted, they cannot be fixed with screws. This kind of fool-like installation settings, the author is still more appreciated.
At the same time, you can also see a lot of cooling holes on the bottom of the TV. On the one hand, it is used to dissipate heat inside the TV. On the other hand, a speaker is set in the middle to facilitate sound transmission. On the bottom right side, LED light display and five-wide navigation keys are set. The author found that the 55D2P TV does not have a dedicated power-on key, but it can be switched on and off by remote control and pressing the arrow keys. Interestingly, after clicking the five-latitude navigation key, the TV screen will pop up a small nine- grid menu, allowing the five-latitude navigation keys to have more choices and achieve more features. This design is wonderful.
Exterior
After installation, one person can pick up the TV and place it relatively easily. You can see Changhong 55D2P TV's front design is very simple and generous, similar to the mobile phone's design language, narrow border, screen share is very good. Light gold metal frame, using anodizing process, superior texture. And this color is almost wild for the living room, without losing the elegance. The back of the TV is also a two-stage design. The circuit board, speakers, and the interface area are all designed at the bottom. What's expensive is that these only take up 1/3 of the area. On both sides, it uses a large-angle arc to make the visual effect excellent. .
The interface area of ​​Changhong 55D2P adopts the L-shaped design, and two USB interfaces are designed in the vertical place. One supports 3.0 and the other supports 2.0. In the tap position, an antenna interface, an HDMI high-definition interface*2, an audio/video interface, a wired network interface, and a digital audio output (coaxial) interface are designed. On the whole, the interface setting is quite satisfactory and can meet the needs of most families. The author also found that at the top of the lower part of the back part, there is also a cooling hole. Combined with the above-mentioned bottom part, there are cooling holes left and right, which can better dissipate the heat generated by the circuit and the lamp, even if It is hanging on the wall and there is no fear of the effect of heat on TV.
detail
In terms of workmanship, the metal brackets are high in firmness and strong in appearance. The bottom is made of silica gel mats. The anti-slip performance is much higher than rubber, and the white transparent silicone is also more beautiful. However, I noticed that the metal frame seems to have to be strengthened in terms of workmanship. Taking into account the price of just over three thousand, this stitching gap is still acceptable.
Changhong's TV is thin as a selling point, in the thinnest place only 11.9mm, compared with a dollar silver coin, only half of its diameter. With the ultra-narrow frame design, the weight of the body is also very light and one person can easily handle it.
Screen quality
Everyone knows that watching TV is to look at the screen. The screen is good for direct impact on the viewing experience. Changhong 55D2P TV screen first uses a 55-inch 3840*2060 resolution 4K screen, but also with HDR function, allows the screen to be more delicate, more transparent, more realistic colors. Here's a test using a professional 4K TV test chart to see if it can be advertised.
As can be seen from the above test chart, the screen of this TV is very good: First of all, it must be a true 4K screen, the text in the enlarged test chart is clearly identifiable, reaching the 4K HD standard; secondly in the grayscale transition, The best of the 4K TVs that have been evaluated before is the 18 value in the upper left corner, and this screen can actually reach 2! This should be the contribution of HDR and dot matrix light control, so that the screen is more transparent, so that the screen level is more clear, while the TV is more power saving; grayscale reduction capability is quite good; in the tone level reduction, zoom in, can also Clearing the display of the 21st level of grayscale did not find the occurrence of the leveling and the parallelism. Finally, in the color performance and visual angle tests, the color of the sphere transitioned naturally, and the color triangle of the color distribution degree was obvious. It shows that the grayscale transition of the screen can see more and more clearly, and the color performance is more abundant and the transition is natural.
Experience the professional contrast black and white tone of the video, standing in the black background of the model, can clearly see the outline of the clothes, wear a white standing on a white background, can also identify the edge of the clothes. This shows that when the screen displays black and white color, the permeability performance is very good. In actual viewing, the dark part has layers instead of blur, and the bright part is not easily exposed.
Through the 4K resolution of the original and actual display photo contrast. In addition to the fact that the white balance of the camera is slightly cold, the detail and color performance capabilities are indeed very close to the original. Explains the 4K screen used in this HDR technology, as well as the dot matrix light control technology, so that the screen effect will indeed look more transparent and the color performance is more realistic.
By playing a 4K resolution demo video, I found that the Changhong 55D2P TV is compatible with 4K video in various formats. She originally used ARM's next-generation 64-bit Cortex-A73 processor, which is a 60% improvement over the previous generation. Above, with 1.5GB DDR4 memory and 8GB of built-in storage. So playing a 4K video is effortless, there is no Caton or there is no sound in the picture. From the screen performance point of view, it is also very visual impact: full color rich, restore the truth. Shadows and light details were preserved, and the transition was natural. Overall, the screen was excellent.
System UI and content
Changhong's TV system is a deeply customized Android 5.1 system. The UI design uses an inverted waterfall design that is simple and generous, allowing users to operate the TV more intuitively. After powering on for the first time, according to the instructions of the wizard, after setting up the network, you can enter the system menu interface. See the menu options are very rich, including: system, select, UMAX, on-demand, music, shopping, education, games, applications, mine, these ten menu options. Of course, there are many small options in each menu. For example, in UMAX, you can watch 4K resolution movies online and automatically recognize Blu-ray titles, which is very convenient to use.
For example, the TV system is cooperating with Tencent's film and television platform. Most of its content is provided by Tencent, but some programs, especially variety shows are only released in a video app. When you enter the selected menu, click on the top content. , Found that sometimes pop-up guide to download the TV APP interface, this design can effectively solve the user in the demand for a particular program, can not find the flaws in the system, the user experience is very concerned about. You can also see that many videos can support up to 4K resolution playback, so that television can make the best use of it.
Eyes tired, do not want to watch TV? You can select music menu, open QQ music and listen to a favorite song. You can also download the APP and enjoy watching the MTV or concert of the star. If you have the amplifier and microphone, you can directly sing a song at home.
What Smart TV buys is extensibility, which is considered by the Changhong 55D2P. Provides its own app store where you can download apps, software, education, games and other APP software. Let Daddy listen to songs and relax and watch movies. Mothers chase dramas and play games. Children watch educational cartoons to meet the entertainment needs of the family.
In the system's own 4K area, the author found a lot of content, including all kinds of movies. The VIP-listed movies are all just coming from the cinema and are updated very quickly. With the remote control, the UMAX viewing function can be opened with a single key, and the stereo surround sound is surprisingly found to be more pronounced. The experience of a relatively large sound field in a theater is unforgettable. At the same time, the screen will be adjusted according to the status of the currently playing screen. For example, when the screen in the above image opens UMAX, the color of the screen becomes warmer, and after closing it becomes more cool. Users who like different experiences can open this function to feel it.
How should I play with 4K TV? After opening the TV with voice control, the king of the mobile phone will be glorified and the screen will be played on the TV. Combined with the hardware configuration of the A73 processor, 1.5GB DDR4 memory + 8GB of storage and distribution, making artificial intelligence control feedback quickly. 55-inch 4K mobile experience. Have you ever experienced it? This visual experience is so cool!
There are many advantages of Changhong 55D2P TV. For example, after installing CHiQ client via mobile phone, it can realize artificial intelligence voice control TV, 2K to 4K times line technology, and so on. It requires users to experience it slowly. In this price TV, I believe that the TV screen with HDR and dot matrix light control technology, the color performance to restore true and delicate, color grade transition natural, more transparent screen, so that the TV is very beautiful. This is the biggest advantage of the 55D2P. Simple and generous in shape, the color is almost a living room. In terms of content and application expansion, it can also satisfy the entertainment needs of the whole family.
