With Windows 8.1, we are introducing wireless display developed on the Wi-Fi Alliance (WFA) Miracast wireless display specification, so you can now wirelessly project to a big screen without fussing with proprietary technologies, network access, and different display cables and adapters. Wireless display is available in new Windows 8.1 PCs – laptops, tablets, and all-in-ones -- allowing you to display your full Windows 8.1 experience (up to 1080p) to large wireless display-enabled screens at home and work.
