Windows 10: How to connect my laptop's screen to my tablet?

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

 

W10 laptop won't connect to network, but Android tablet wilI

I run Windows 10 on an old Dell laptop. This afternoon, I suddenly lost my Internet connection. I keep getting a message asking for the "network security key," which is, apparently not the same as the password. However, my Android tablet (on which I'm typing this) is connected to the same network. I have a few interrelated questions:

1. Why would my connection suddenly drop out like this?
   
2. What is the "network security key?"
   
3. How do I fix this situation?
   

Please explain things step by step.

Thank you.

 

Transfer music from laptop to windows 10 tablet.

No, there's no pop up on the tablet or the laptop. I have tried using the three different USB ports and still nothing but I only have one lead to try. I clicked windows key and E and the tablet isn't listed under my PC, but it is listed in network as a phone,
don't know if that's relevant
