The TV industry has changed again and again, LCD TVs have begun to occupy the living room of the people. The first TV upgrade was in 2010. At that time, more than 5,000 yuan worth of 25-inch SONY CRT TVs would be retired, trade-in replacements, and a discount of RMB 400. For a Philips 46-inch LED LCD TV, once bad in previous years, just in the three-year warranty period, free replacement of the motherboard, see the results can be. This year is the year of the Olympic Games. Watch the game can not be without a big screen. Plus the current civilian price of TV, TV has to be replaced. The price of the big-screen 4K TV is no longer astronomical. The 4K TV on the big screen has become the current trend. I decided to make a second TV upgrade.
According to my many years of experience in selecting several TV standards, upgrading once will not be eliminated for at least five years. Specific requirements are as follows:
1. Select domestic brands, domestic brands and imported brands are no longer different, and prices are more affordable;
2. 4K, it can provide 3840 × 2160 four 1080P resolution, can display more details in the TV screen, significantly enhance the clarity of the picture;
3. Consider taking the living room, watching distance is about 4 meters, 55 inches is most suitable, too big is not necessary;
4. Select "Response time" fast. Response time is an important performance indicator of LCD TVs, also called response speed, 4ms is the first choice, so that watching games will not be trailing;
5. Select the interface with the new standard. USB3.0 is indispensable, for high-definition interface HDMI, at least should be equipped with a HDMI2.0. Interfaces with these new standards not only support more new devices, but also provide higher transmission speeds, making the picture clearer;
6. TV must be intelligent, one machine is versatile, has the functions of digital cable TV and Internet TV, watching TV live, seeing broadcast, playing games is indispensable.
To sum up, weigh the advantages and disadvantages, and finally decided to choose a domestic brand, has many years of television development, production experience of Hisense's LED55EC520UA ultra clear 4K 55-inch smart TV.

Open the box, install two brackets, and put it on the TV cabinet, which is larger than my original 46-inch TV. The bracket design is very reasonable, and it is much more stable than the previous base structure.
There are no accessories in the box, an instruction manual and a remote control
The remote control feels good, the size is appropriate, and the sensitivity is high
The interface on the back is fairly rich, except that there is no VGA interface, everything, there is a USB3.0 and two USB2.0 interfaces, three HDMI, two of which are 1.4 interfaces, one HDMI2.0 interface, one wired network port, The AV input and component input interfaces are reserved, and there is a set of digital audio coaxial output interfaces that can be used to connect power amplifiers, a TF card slot, a TV antenna interface, and a Smart Card smart card slot.

Can support to 3840x2160P 60Hz, I connect the latest cloud network CR18S on HDMI3, this box is to support HDMI2.0 protocol, open the display settings of the box to see HDMI mode
HDMI mode finally appeared 2160P 60H, but Ycbcr420 format, indicating that the TV is to support 3840X2160 60Hz resolution, is a real 4K TV
f. Hisense LED55EC520UA uses 1.5G DDR3 and 4G eMMC internal memory. After installing some common applications, the memory is less than 1G. It seems that 4G is not enough, if 8G is enough
g. Switch the source of the program, press the left and right arrow keys of the remote control to switch the selection source, switching is very convenient
h. The media center, each section of the design is very user-friendly, easy to use, easy to use!
Third, software articles
Hisense LED55EC520UA software industry is very good, embedded "available," "gathering," "gathering together" and "a lot of learning", also joined the "WeChat Internet TV", "poly" and "cool play gym" Content content is extremely rich, compared with the general network set-top box can not be compared to nothing.

Two weeks of centralized use, no one crashes, the system is also quite stable, the TV during the 315 event as long as the price of 3,099 yuan Jingdong can buy, high cost, is the ideal choice for replacement.
Inadequacies:
1. 4G's internal memory is too small, it should be upgraded to 8G, otherwise "juggled" is the decoration, there is no space to install the game, let alone large games;
2. Buy TV, the first demand is to watch TV, can not receive direct broadcast cable TV, the smart card inserted into the SMART CARD, can not enter the cable digital TV search console interface, can only simulate the search station, and now the analog signal stops The terrestrial wave TV also failed to receive the TV. The TV receiver received the cable through the TV set top box. The AV output had poor image quality, and it could not receive the HDTV. Instead, it used two remote controls to switch back and forth. Others included SMART CARD kcal TVs. On the small card can receive cable digital TV, and LED55EC520UA parameters clearly indicate "support for cable digital TV", which is also a major selling point, but now it can not be used, disappointed!
If the digital cable TV is opened, the box manufacturer will go bankrupt. The Hisense LED55EC520UA is a TV that does not need to connect any set-top box!
