![]() You can share screen directly from an iPhone to an Apple TV using Airplay. Tap the icon, and then select the device where you want to view the screen. Once installed, the installed chromecast icon will appear in supported apps. ![]() Once the chromecast dongle is connected to the television, download Google Home Companion app to connect the device with your home wireless network. Ĭhromecast is the wireless technology developed by Google that can be used to watch content wirelessly from your iPhone with any LG Smart TV.Ĭhromecast allows you to send video, audio and pictures and information from thousands of supported apps such as Netflix, Hulu and many more.Other alternatives to mirror your screen: This however is not going to mirror your screen, it will only play and control the individual content from your LG TV. Some apps such as Youtube, Netflix and Hulu already have built-in functionalities to help you cast videos and content from your iPhone to any LG TV. With wireless display, you’re only granting them access to the display… not to your network.Show All + Close All - Share using Cable e.g HDMI Share using Wi-Fi Share using Bluetooth This means that you can allow a guest (corporate or home) to project in your conference or living room without you having to grant them network access (which could potentially give them access to other devices and content beyond what you might have intended). Miracast is different, in that it is peer-to-peer, going directly between Windows and the receiver, and not over the Wi-Fi infrastructure network. ![]() Some of the alternatives work well in home environments, but have difficulty in corporate and hotspot environments where the receiver has to authenticate onto the network using enterprise-grade security such as WPA2-Enterprise or hotspot style authentication using a captive portal. Not all alternatives support full HD (1080p) and instead top-out at lower resolutions below what your TV/projector may natively support. There are other wireless display (“screen casting”) alternatives, each having their own advantages and drawbacks when compared to Miracast. This is, of course, just a high-level explanation of the steps involved, with the Wi-Fi Alliance Miracast site having more details including the full specification. Anything your Windows PC has access to, you can wirelessly display on your big screen. Once capabilities are agreed, Windows begins projecting its display and audio onto the remote device by encoding the local display and sound, and sending to the receiver, where the receiver decodes and displays. Once communication is established (2.4GHz by default or 5GHz if pre-connected to 5GHz AP), the source and receiver negotiate capabilities – e.g., the resolution and refresh rate (e.g., 30Hz), content protection scheme, audio channels, etc. Security is negotiated using Wi-Fi Protected Setup (WPS), with communication secured using WPA2-AES directly between the Windows device and Miracast receiver. It begins with the discovery of available Miracast receivers, and then proceeds to establishing a point-to-point connection between the source and receiver over Wi-Fi Direct. For those interested in the nitty gritty of how wireless display works, here’s a quick rundown.
