Screen mirroring on pc
You can try AllCast witch only require a working Wi-Fi connection.

It works pretty great for me (Xiaomi Redmi Note 4 Pro, Android 6.0) :


Download here
On your PC, in Chrome, install AllCast Receiver


Make sure both your phone and laptop are connected on the same wireless network and then :


Open Mirror Beta and select your computer


AllCast Receiver will show up on your computer mirroring your Android screen.
Hope this will work for what you need.
