What choices can TV need to measure? Personal consideration of hardware performance and functionality is necessary. Buying a cost-effective smart TV product is not only a matter of viewing the screen size but also measuring hardware performance and functionality. In this 4K era, 4K smart TVs have become the basic criteria for each user to purchase TVs. Based on this quasi-side editorial, how to correctly select smart TVs through the hardware parameters of the chip. What is the most important thing to buy a smart TV?
With the increasingly complex functions of smart TV systems and more and more applications, the requirements for chip computing performance are also increasing. The performance of the chip depends on the number of CPU cores and the operating frequency, which will affect the smooth running of the UI system and various applications and games. Nowadays, smart phones are generally quad-core and eight-core, and TVs cannot lag behind.
The strongest chip in smart TVs in 2015 was MStar's MSD6A928, which uses a quad-core ARM Cortex-A17 design to run smoothly all existing applications. With super 4K decoding capability.
Considering that the Cortex-A17 and Cortex-A53 have become mainstream, the use of Cortex-A7 and Cortex-A9 TVs is a bit worrying. Although the fluency of the UI can be guaranteed by simplifying system functions, smart applications in the future may be Can't run smoothly. And because the resolution of 4K TV screen is 4 times of 1080p, it is higher to require computing performance too, A17, A53 chip should be the first choice when buying.
Second, GPU graphics processor
The GPU's role is similar to that of a computer's graphics card, except that the TV does not have a discrete graphics card. The GPU and CPU are integrated on one chip. Many of my friends would have experienced this: using a very high-profile computer, running software or browsing the web is fast, but playing a game is very card - because of poor graphics performance, causing a bottleneck. The same applies to smart TVs. GPUs are primarily responsible for graphics rendering. This is especially important for games. It requires strong GPUs and CPUs to provide a smooth gaming experience.
Currently, there are several GPU models in smart TVs, such as PowerVR SGX series and ARM Mali series. The previously mentioned Mstar 6A928 chip integrates the MaliT760MP4 quad-core GPU, which basically meets the requirements of games under the Android platform.
In addition to regular games, the powerful GPU can provide more gameplay. For example, LeTV X50 Air provides a 3D game function. Through special settings, games that support OpenGL technology can be converted into 3D games. Currently, over 300 games support this technology. Wearing 3D glasses, you can not only enjoy 3D movies on the X50 Air, but also play interesting 3D games - of course, if you have a strong GPU, because GPU rendering graphics workload will be doubled in 3D mode, If the performance is not enough, it is easy to get stuck in the picture.
Third, 4K decoding capability
The aforementioned core number and frequency refer to the CPU part, which is equally important for smart phones and smart TVs. However, televisions are used to view video, so more needs to consider video decoding capabilities, especially 4K video decoding capabilities, this part is the difference between television and mobile phones. The mainstream TV chip will integrate the decoding circuit with the CPU on the same chip to save cost and power consumption.
A few years ago when 4K TV was first born, there were some models. Although 4K LCD screens were provided, but they did not support 4K video decoding, they were called "Fake 4K." We must now purchase 4K TVs and we must not commit such low levels. error.
However, we must also pay attention to whether the chip supports 4K format. At present, 4K video mainly includes H.264 and H.265. The former has been available for 10 years and is commonly used in 1080p full HD video. The latter is the new standard and is designed for 4K and 8K ultra high definition video. of.
According to the data, video files with the same video quality generated by H.265 encoding are half the size of H.264. This means that H.265-encoded 4K video not only occupies much less hard disk storage space than H.264, but it also occupies very little bandwidth for watching H.265-encoded 4K video online.
The previously mentioned 4K TV dedicated chip: Mstar 6A928 supports both 4K decoding of H.264 and H.265 formats. TVs that only support H.264 will obviously be in an awkward position after a large number of 4K content will appear in the future, and it will be inconvenient to buy a home. If you want to see 4K video in H.265 format, you must connect a TV box or a computer.
Fourth, RAM operating memory
Running memory is relatively simple, mainly depends on the size of the capacity, many old smart TV menu response is very slow, often crashes, one of the main reasons is the memory is too small. Today's Android 5.0 and above systems are increasingly demanding on content, and mobile phones with 1GB of memory are very slow, not to mention smart TVs, so 2GB is the most basic requirement.
However, some manufacturers use å¿½æ‚ tactics when promoting, for example, a TV memory is only 512MB, but when it is advertised, it is 4Gb. This is to play a word game, because 1B = 8b (B is the abbreviation of Bite, b is the abbreviation of bit), we must pay attention to when purchasing.
Fifth, performance + appearance
If you want the same performance and appearance, personal advice to buy split TV, one machine performance, especially the sound quality is not perfect, "split TV" is basically enough configuration, experience enough, can put the sound quality and quality All are better reflected. Personally recommended LeTV, Nigeria, Sharp, if it is based on cost, then choose the domestically made is always right. Let's take 65 inch as an example, high-smooth dynamic + colorful static painting, thin screen also has flagship quality, with 3/4GB memory, A72 architecture quad-core processor, Mali series GPU and 32GB of large memory, split TV The special structure allows you to choose the program to use based on different scenarios and needs.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
