Overview of Intel® WiDi Dual Screen Enabling
Intel® WiDi and Dual Screens: How They Work Together
Dual Screen applications provide a new user experience that takes advantage of two screens: your PC or tablet and your TV. A dual screen-aware app can provide a simple user interface for searching, curating, and configuring on the PC with a natural touch interface while displaying the media and related content on a TV screen with a quality sound system. This all happens using Intel® WiDi technology, an implementation of the Miracast industry standard, on both Windows* 8.1 (desktop and Modern UI apps) and Android* 4.2.2. Based on industry standards, the number of compatible devices is rapidly growing. More than 50 million PCs have shipped with Intel® WiDi software preinstalled.
One App, Two Screens
Intel® WiDi technology creates a wireless connection using existing Wi-Fi* in your Intel® architecture-based PC, tablet, or smartphone to a Miracast receiver; a TV, STB, OTT, or adapter. With Intel® WiDi running, there are no additional apps needed on the TV or receiver. One application on your PC controls both screens. The app can format the TV screen to smoothly display animated social network feeds, photo streams, and play videos — even multiple camera angles — all at the same time. Since the app is running on the PC, the full throttle capability of the CPU and GPU is available. The only requirement of the receiver is to receive and play the 1080p video sent by the PC. To create a Dual Screen app, the developer uses the same Windows desktop APIs for any second monitor (Intel WiDi, HDMI, VGA, etc.). For Windows* Modern UI or Android* there are simple APIs to expose a second surface for the application to render to.
