Intel Wireless Display (Intel WiDi)

What is WiDi?

WiDi, the popular name for Intel Wireless Display, is a display connection technology that allows people to extend their laptop screen to their TV — no cable required.

Introduced in 2010, Intel WiDi now supports up to 1080p high-def resolution, 5.1 multi-channel audio and HDCP, which means you can now beam DVDs, Blu-ray Discs and movies over the air.

What can I do with WiDi?
WiDi works like an HDMI cable connected to your TV, allowing you to multi-task on the laptop screen while another application or media player runs on the TV screen, except you can keep your laptop on your lap — no cable. Imagine watching on TV the video you made of your kid’s birthday party while telling your friends on Facebook how glad you are that it’s over.
While some set-top boxes, game consoles and Blu-ray players offer internet services, they’re usually limited to a vendor-chosen subset of services enabled on the device. With WiDi, no such limitation exists. Tour Google Earth, explore massive photo mashups, play the latest pre-beta music service — if it’s on your computer, and you can beam it to your big screen (and big speakers if you have a receiver that takes HDMI).

WiDi on First Generation Intel Core Processors


How does WiDi work?
Processor graphics render a second virtual display, which is broadcast via WiFi through a feature in Intel Centrino wireless chipsets called My WiFi. On the TV side, a receiver converts the signal and passes it to the TV. The receiver is available as an add-on adapter and a growing number of multifunction TVs, Blu-ray players and set-top boxes are coming to market with WiDi receiver adapters built in.
The connection between the laptop and the adapter is managed by Intel WiDi software that runs on the laptop — the wireless driver, graphics driver and wireless display software are available for downloadfrom Intel. An additional app called Intel WiDi Widget simplifies the task of configuring the Windows settings to achieve the correct resolution and displays the active window on the TV with a single click.


Where can I find WiDi devices?
WiDi is available in more than 100 laptop designs in virtually every major market around the world. Belkin, Netgear, D-Link and other OEMs offer display adapters. In stores, look for the Intel WiDi logo.

How to tell if you already have a compatible PC?
Type WiDi in your Windows* search bar. If your PC has built in Intel® WiDi, you will see ‘’Intel® WiDi’’ application in your search results.

Already Have a Compatible PC But Need an Adapter?
If you have a compatible PC, you just need a digital adapter to complete your set-up. With a digital adapter you can stream media content wirelessly from your laptop to other devices including TVs and stereos. Digital adapters are also known as push to TV adapters, digital media hubs, digital media extenders, and digital media streamers.
