A:Answer Hi WB, Unfortunately, the X80J doesn't have screen mirroring. However, the X80J has a built-in Chromecast. Chromecast lets you cast your favorite videos, games, and apps from your mobile device in full quality to your Chromecast built-in TV. Just one tap of the Cast button on your Android or iOS screen is all you need to supersize the things you love. Cast your content, then continue browsing on your phone or tablet.
For more details about the Chromecast Built-In, please check the link below:

Also, this TV supports Apple AirPlay and Apple Homekit. Use Apple AirPlay to mirror the display or stream content from your Apple devices to your Android TV.
