We often use mobile phones in the office, and then we have to lower our heads to operate, not only the cervical spine can not stand it for a long time, but also be mistaken by others for playing with mobile phones.
If the mobile phone is projected to the computer, then this problem can be solved, and it can also improve work efficiency.
I've seen a lot of people use scrcpy, an open source software, but this software is more complicated to use and not very friendly to computer beginners. So I will share with you two software developed based on scrcpy, which are also free, and you only need a data cable, you can cast your phone to the computer. Before I recommend it, I want to emphasize two more points, both of which are free to use and are only available for Android phones.
*Link: Recommendation Index: Five Stars This software is simply impeccable, not only the picture is clear, the control is smooth, but also the functions are also very rich, you can adjust the screen size, screen casting, screen recording, file transfer, etc. What's more, it can also call the computer keyboard, and the chat tool on the mobile phone can also be entered with the keyboard, without having to click on the mobile phone.
The connection steps are as follows:1. Connect the computer with an Android data cable.

3. Reconnect, open the ANLINK software, and click Refresh to connect. 
Then enable the Windows input method, you can use the keyboard to type.
This software is the same as the one above is the software developed by scrcpy,The same connection method,But there is one more step,To switch only the power supply to the transfer file can be recognized,After identification, you can cast the screen。
But this software has more ways to play than the first software, such as switching screen projection devices, or copying multiple phone screens at the same time, and the interface is relatively simple.
There is no official ** address for this software, if you need to pay attention to me and send it to you.
Note: If the above two software are used at the same time, there will be conflicts, and abnormalities may occur.
