What are so many ports behind the TV used for? I figured it out after reading it
Although everyone is accustomed to watching programs on the Internet and does not rely so much on TV, there is still a TV in every house. If there is no TV in the house, it seems like something is missing. Now TVs are all LCDs. If you have seen the back of the TV, you will find that there are many ports on the back. What are all these ports for? I figured it out after reading it
In fact, before we buy a TV, we must observe the ports on the back of it, and also know their purpose. On the one hand, it can ensure that the ports we need to use frequently are not damaged. On the other hand, it can also help us better. Use the functions of the TV.
Nowadays TVs are pursuing high-definition, and they have entered the pace of intelligence. The HDMI interface has become a must-have interface for TVs. To watch TV now, you need to install a set-top box, and HDMI is the interface that connects the set-top box and the TV. In some families, one set-top box is not enough, and two set-top boxes are often needed. Therefore, this interface is not only important, but also needs a few more, so a TV It will be equipped with 2-3 HDMI ports.
There are currently two HDMI interfaces on most of them, one is 1.4 and the other is 2.0. With this interface, you can play online games on the TV. Compared with 2.0, the frame rate is higher. When playing games, Yong 2.0 is the best, so if you like to play games online, you must check if your computer interface is 2.0.
The USB interface is also very common now. Through this interface, we can connect to devices such as cameras and gamepads. If the phone is out of power and the other sockets in the house are full again, you can also use this to connect with the phone to temporarily charge the phone. Friends who like to watch movies at home can buy a TV with a USB3.0 connector, because its transmission speed is ten times that of 2.0, so that you can enjoy ultra-high-definition at home and a very smooth experience. It's most suitable for people who don't want to go out but want to feel like being in the theater.
There is also an audio output jack that is most commonly used. If you want to connect the TV to the speaker for power amplifier, you need to use this jack. If you don't have this jack, it doesn't matter, we can also use a coaxial cable to output. Now there are some smart TVs that have a memory card slot. Through this card slot, we can insert an SD card. Having this card slot actually saves us a lot of things, so we want to watch ourselves on the TV. When using the camera album, just pull out the SD card from the camera and plug it into the TV. You don’t need to transfer it to the USB flash drive.
Nowadays, many electronic products are already intelligent. I can't imagine that the TV a dozen years ago was still a small screen and a huge machine behind it. Now it has become thinner and thinner and its screens are getting bigger and bigger. Some screens are no longer conventional, and people are looking for more and more functions.
