How to Wirelessly Mirror a Windows Laptop to an HDTV
In all Windows 10 and Windows 8.1 computers, including laptops, there’s a built-in capability for mirroring your screen on a television called Miracast or Wi-Fi Direct. There are a few things to keep in mind, though:
Both the television and the laptop need to be connected to the same network.Your laptop and TV both should be current and completely updated with any operating system patches or security updates.It is possible that a laptop that was upgraded from an older version of the operating system may not support Miracast (because of outdated hardware).While most HDTVs will support Miracast, there are some that do not, and you will not be able to mirror your laptop to those TVs using Miracast unless you buy a separate Miracast dongle.
As long as your computer and your TV support Miracast, mirroring your TV should be a simple process.

On Windows, you can then use the keyboard combination Windows Key + P to open display settings and choose how you want to display/mirror your laptop screen.
