If you have an Android phone like the Meizu Pro 7 Plus, you can easily use Miracast to wirelessly share your screen with a larger display such as the Miracast-supported Samsung MU6300 4K UHD TV.
First, make sure to connect both the Meizu Pro 7 Plus and the Samsung MU6300 4K UHD TV to the same Wi-Fi network.
To enable Miracast from the phone, go to Settings -> More -> Wireless display, and select the Samsung TV when it appears as 'Samsung 6 Series (43)'. Make sure to switch on the Wireless display button in order to automatically locate the TV.
Select the Samsung TV and you will immediately see the phone's screen on the Samsung MU6300 4K UHD TV once successfully connected with the Meizu Pro 7 Plus.
Despite the occasional lag and pixelation especially when watching action movies or playing games, the Miracast technology works fine to enable you to remotely screen mirror your Meizu Pro 7 Plus with the Samsung MU6300 4K UHD TV easily.
