Intel Wireless Display , abbreviated to WiDi , was a technology from Intel that made it possible to stream the screen content of a desktop computer (with a WiDi-capable mainboard) or notebook to a compatible device (television, video projector, HDMI adapter, etc.). WiDi can thus be seen as Intel's competitor to Apple 's AirPlay technology . In 2016, Intel announced that it would no longer support this technology in favor of the Miracast standard .

Both the duplication of the existing screen content and the extension of the screen by another device are supported. In addition, specially adapted applications enable selected content to be displayed on a second screen.

history

Intel Wireless Display was first presented in version 1.0 at CES 2010, but could only reproduce 720p and stereo sound .

At the CES 2011 version 2.0 of the technology was presented, which could already play back video clips in Full HD ; Another innovation was the transfer of HDCP -protected Blu-ray Discs .

Version 3.0 was released in April 2012, which was already able to play video clips in Full HD at 60 FPS , followed by version 3.5, which was released in September 2012. With this version it was possible to access connected USB HID .

Version 4.0 was introduced in 2013, followed by version 4.1 and 4.2 in 2014.

Version 5.1 was presented in 2015, which was the first to be able to transmit a video resolution of 4K .

Version 6.0 was released in August 2015, and in October 2016 Intel announced that it would discontinue the technology.

requirements

In order to be able to use the technology, the notebook or tablet that is to be used as the source must meet two hardware requirements:

On the one hand, at least a 2nd generation Intel Core processor ( Sandy Bridge ) is required and, on the other hand, a WLAN module from Intel that supports the WLAN transmission standard 802.11n (status: 2017). At least Windows 7 is required as the operating system . Intel Wireless Display supports video resolutions up to 1920 × 1080 pixels , the 1080p standard of the television standard High Definition Television .

The transmission of copyrighted content is now supported by using HDCP 2.1 . Although the WLAN module is used for transmission on the notebook side, surfing the Internet at the same time is possible.

Miracast

Intel gave up its proprietary WiDi standard in favor of the open Miracast standard and uses Miracast to transmit the data necessary for streaming. Version 3.5 of the Intel WiDi driver, available since October 2012, already supports sending to Miracast receivers. Intel itself sees wireless display as an implementation of the Miracast standard for end customers.
