Windows 10: How to force miracast to always start on extended mode?

This is extremely frustrating. Using wireless display from a laptop , one often closes the lid. Doing so, "when" the wireless monitor disconnects at that time, the next time one connects, they are forced to "Second Screen Only". It should never change a setting that was never used on the machine, or even by the user on an other machine. I'm sick of nearly every time I connect to the TV, I loose my monitor. I mean ****?Is there a registry key or anything that can permanently disable "Second Screen Only"?

Hi there Alainpraet!

Step 1: If your TV comes with built-in Miracast support, then turn it On. ...

Step 2: Now on your Windows PC, navigate to Start -> Settings -> Devices -> Connected Devices.

Step 3: Click on 'Add a Device' and wait for the adapter to appear in the list.

Now try to connect.
