If you don’t want to use your old Android phone at home, then what should you do? Originally belonged to the same product of the Android camp. It is a pity that it is idle. It is worthless to sell it, and no one wants to send it. So why not use it for waste? Today Xiao Bian came to teach everyone the use of waste to see exactly how to make smart TV boxes from old mobile phones. Prepare items: An idle Android phone, the MHL extension cable is used as an example today. The box indicates that the maximum resolution that the phone can connect to the TV is 1080p. The clarity is good After connecting, the mobile phone becomes a game console, smart TV box, and no longer needs to watch movies on the small screen of the mobile phone. On the back of the box, note that "MHL must be powered by an external power supply (5V 1A), otherwise it cannot be output to HDMI.", so this line has a USB interface dedicated to the charger to supply power. Take a look at the wire work, first connect the micro-usb port of the phone, the main function of this connector is to receive the video signal from the phone. An ordinary USB port connected to the charger can be powered through this interface to allow the output quality to reach 1080p. ã€Instructions】 The HDMI interface of the MHL line is connected to the HDMI port of the TV. You don't need to install a driver to connect to the TV, nor do you want to restart the device as you said on the Internet. You can read it directly! No other messy steps are needed at all. You can also watch live TV directly, and the picture quality is very clear The screens of the mobile phone and the television are completely synchronized, with no lag or delay. Changing the station is very convenient, and it can be directly operated on the mobile phone. After the mobile phone becomes a TV box, you want to install what video broadcast software to install, you can directly install a sofa butler, sofa butler inside there are many live TV software, watching live broadcasts are very easy. Summary advantages: The transformation cost is relatively low, only 30 yuan, only about 1/10 of a TV box, but the function is no different from the TV box; plug and play, no need to drive, the operation method is simple. Disadvantages: When watching a video, the phone can't turn off the screen. If it's off, the TV will be black screen. The heat of the mobile phone screen is very obvious. My response is to put the phone on the air purifier screen towards the outlet. If it overheats, the phone will restart; The mobile phone realizes the live broadcast, so unlike the TV box, there is no remote control, and any operation is to be realized through the mobile phone screen. 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, TV boxes, smart TVs, smart TV software, etc. Answering questions.
