The wireless display industry is expected to grow from $1,2 billion in 2012 to $4.7 billion by 2025. This growth is driven by consumers looking for ways to enjoy entertainment on their TVs without connecting devices via cables. The number of households with multiple connected devices continues to increase, with over half of homes now containing three or more digital devices. As a result, companies have many opportunities to enter the market.

In addition to the growing demand for high-definition displays, manufacturers are developing innovative solutions to address consumer needs for convenience and ease of use.

Intel announced in May 2010 that it had begun work on a wireless display technology called “WiDi.” The technology lets users wirelessly stream media from their computers to TVs via adapters.

At the Consumer Electronics Show in January 2011, Intel demonstrated WiDi technologies running on a laptop and a desktop monitor. In February 2011, Intel announced that Microsoft Windows 7 would include native support for WiDi.

In April 2012, Intel announced that it had completed the development of WiDi 2.0, which offered better performance and compatibility with newer devices.

On June 14, 2013, Intel discontinued WiDi due to lack of interest among consumers and adopted the Miracast standard Windows 8.1, another wireless display standard developed by the Wi-Fi Alliance.

With Windows 10, the built-in wireless feature is called “Project,” which allows you to mirror the screen of your PC to a TV if it has Miracast support. Today we will review the WiDi history and versions in this article.

What is WiDi?

WiDi is a wireless display technology developed by Intel that allows users to stream content wirelessly from their computers to TVs and monitors. WiDi requires the computer’s CPU, GPU, OS, and wireless network to be working properly.

  • WiDi 6.0 -Release in 2015
  • By October 2015, Intel had stopped developing WiDi technology.

WiDi vs Miracast, Which One is Better?

WiDi is a wireless display technology developed by Intel, while Miracast is developed by Wi-Fi alliance.

WiDi and Miracasting are based on Wi-Fi Direct technology with the same usage, allowing users to stream content wirelessly from their computers to TVs and monitors; however, WiDi has better video quality and lower latency compared with Miracast.

Miracast has broader compatibility than WiDi, which works with laptops, smartphones, and tablets. WiDi requires specific hardware and software requirements about the CPU, GPU, and OS, making it less flexible; that’s why Intel discontinue the WiDi technology.
