What do you care about when buying smart TV? Do not ignore these parameters

1. The screen and picture quality screen is the most intuitive embodiment of the TV function. Regardless of the smart TV, a good screen always brings people the most enjoyable viewing experience. Now in this smart era, video is getting more and more high-definition, and you want to support high-definition video signals. Most mainstream screen displays use 4K ultra-high-definition resolution. Therefore, if you choose a smart TV, from the perspective of the screen, first look at whether there is such data:

Screen Level: The screen level is divided into five levels, mainly reflecting whether there are dead pixels and bad points on the LCD panel. For LCD TVs, the screen level must be at least above A to qualify.

A++: There is no bad point
A+: 1-3 bad spots
A: Less than 5 bad spots
B: 6-10 bad spots
C: 11 bad points or more

Screen resolution: 4K Ultra HD, referring to a resolution of 3840 × 2160 pixels, four times the 2K (1080P) TV, able to display more details, significantly enhance the clarity of the picture.
Technical Support: HDR Technology, MEMC Motion Compensation

2. The CPU of the core processor smart TV is also the core of the computer. The processing speed of the data directly affects the response speed of the TV. At present, the larger brand choices are basically four-core CPU processors, most of which are MstAR chips. As GPU graphics processors are generally integrated with a CPU on a chip, it is also necessary to pay attention to what processor is used.

3. Memory and Flash Memory Since it is a smart TV, memory and flash memory are very important. Memory is mainly used to store user-processed data. The larger the memory, the smoother the TV operation will be. Flash memory is used to store files such as APPs, videos, pictures or music downloaded by users. It is equivalent to a computer hard disk. The larger the memory, the more files that can be stored.

4, response speed TV response is mainly reflected in the playback video screen whether there will be residual image or fuzzy phenomenon, especially when the motion picture is more obvious, it shows that the TV response time is longer, now more and more high-definition signal source, The long time for the TV picture to respond will affect the effect of HD. When you buy, you must observe more and see more pictures.

5, the interface TV as a home large-screen terminal, involving many external devices, so the interface is complete and how much the number of need to view, USB interface and HDMI interface must have at least SD slot sometimes used. Also note that the standard of the interface should also pay attention to, for example, USB3.0 is much faster than USB2.0, and HDMI2.0 is much faster than HDMI1.4.

6. Delaying the function of smart TVs is not just watching TV, but also taking on more entertainment functions, such as games and interactions. This kind of video signal input from the outside, if the delay is obvious, will affect the game experience.

7, energy consumption All household appliances should pay attention to power-saving performance. The energy efficiency rating of home appliances in China is divided into 5 levels, with the figures from low to high, and the energy-saving effects from low to high. Level 1 indicates that the energy consumption is the lowest, Level 2 indicates that it is relatively energy-efficient, Level 3 indicates that it is general energy-saving, which is China's current market level, Level 4 is lower than the market average, and energy consumption is high. Level 5 is the lowest standard of energy consumption of the product. The highest consumption. At the time of purchase, it is recommended to purchase products with an energy efficiency level of at least 2.

The choice of smart TV, in addition to considering the CPU and memory, the other is basically the same with ordinary TV, as long as you master a few key core points, do not blindly look at the business promotion, or can choose to really make you satisfied with the product .

Connecter Color-coded Pigtail

With the widespread application and rapid development of optical transmission equipment, the use of optical patch cords (ODF) and pigtails in the communication room has also increased dramatically. However, many units do not pay much attention to this aspect of management. The gathering of hundreds of pigtails from all directions to a certain location is a big test for the cleanliness and beauty of the computer room and the safety of business transmission. It can often be seen that after many pigtail jumper operations, the originally neat pigtails and optical jumper racks often become messy, difficult to sort out, and difficult to remove when they are not used. Not only has it seriously affected the appearance of the computer room, but also brought inconvenience to future operations, and also brought a greater threat to the security of the ongoing business.
The ODF rack should be distributed:
It is often seen in the equipment room that certain sections of the trunking are covered with pigtails, overlapping each other, while the pigtails in other trunks are very few. The occurrence of this situation is not conducive to the safety of the transmission business, but also It is detrimental to the beautiful environment of the computer room and causes a waste of resources. The main reason for this phenomenon is that the layout of the ODF rack in the computer room is not reasonable enough, and a large number of equipment that needs to use optical fibers are concentrated in a certain direction of the ODF rack. In order to avoid such phenomena, consideration should be given to the design and construction of the computer room. The ODF frame can be set in the center of the computer room to facilitate the pigtail to reach any position in the computer room, and the distribution of optical transmission equipment in the computer room should be considered.
Set the ODF jumper:
For the failure to make a reasonable layout during construction and design, or for some reason, there is indeed a large number of equipment that has a huge demand for optical fiber resources in a certain direction of the ODF rack, and the sub-ODF rack should be installed appropriately according to the situation. Replace a large number of optical jumpers in the trunking with optical cables. The sub-ODF rack is installed at the near device end. When performing fiber jumper operations between the equipment in the cabinet and the ODF rack, first jump to the corresponding sub-ODF rack and then jump from the sub-ODF rack to the equipment in the cabinet. But it should be noted that this kind of design will have a certain degree of optical attenuation, and the loss of experience value increase is below 1dB.
Optical fiber routing channel:
Due to the limited space resources of many computer rooms, generally only one cabling channel is set in the computer room, and the pigtails are routed together with the electrical signal cables. Because the pigtail is afraid of pressure and lacks a protective layer, if it is not protected by a sleeve, the pigtail is easily damaged and safe transmission is threatened. If the pigtail is protected by a pipe, the pigtail will not be threaded a few times, and the cable duct will be full. The arrival of the trunking is a waste of resources and is not conducive to the beauty of the computer room. If you can use special fiber optic cable routing channels. It can save the pigtail through the pipe protection, which saves resources and is conducive to the beautiful environment of the computer room.
Selection of ODF frame:
(1) There must be sufficient space for storing redundant pigtails.
(2) The flange interface of the ODF frame should be convenient for maintenance. If there is a problem with a flange interface, pull out a certain row where it is located, replace it and use it. (The commonly used ODF frame has 12 flanges as a unit, repairing one core will affect the other 11 cores).
