Intel WiDi is a wireless display technology that lets you beam content from recent Intel-powered devices to a TV or monitor without an HDMI cable.
WiDi has been available for a few years, but with the launch of Intel’s 5th-gen Core and Intel Core M processors, the chip maker is unveiling WiDi v5.1 for Windows 7 and later.
The update brings support for security, privacy, and presenter controls for use in business environments as well as support for full-screen games using DirectX 9 and DirectX 11.
If you’re using a system with a 5th-gen Intel Core chip, you can also now use WiDi to send 4K Ultra HD content to an external display wirelessly, although you’ll need a driver update which is coming this month to support 4K content.
There’s also a WiDi remote application for Windows that lets you clone or extend your PC display.
Intel is also announcing one of the smallest, most affordable WiDi adapters to date. The ActionTech Mini2 is an HDMI stick that you can plug right into the HDMI port on your TV or monitor. It has a suggested retail price of $40, allowing you to turn pretty much any screen with an HDMI port into a wireless external display for your notebook or tablet.
At that price, the WiDi adapter is actually a little more expensive than a Chromecast or Amazon Fire TV Stick, but neither of those devices supports 4K (or are designed for use specifically with Intel and Windows products).
