Rooted Devices
Rooted devices can use Miracast technology to mirror the screen. If you have a TV that supports a Miracast connection, you already have everything you need to mirror the screen from your Pixel to the TV. Every TV links up differently. Check the documentation on your particular TV to find out how to connect a device via Miracast.
If your TV does not support Miracast, you can use a set-top box that supports it. The most commonly used are the Roku and Amazon Fire TV. You could also use a Miracast Video Adapter.
Enable Miracast on your Pixel by editing the build.prop file using these steps.
1.Download and install BuildProp Editor.
2.Select Menu icon at the upper-right corner, then choose “Add” > “New“.
3.Set the property name to “persist.debug.wfd.enable“, then set the Value to “1“.
4.Restart your device.
You will have the ability to now cast your screen to a Miracast device. Enable the option under “Settings” > “Display” > “Cast” > “Menu” > “Enable wireless display“.
