Enabling Wireless Display (WiDi) on Windows 8 Consumer Preview

Chances are that if you have upgraded your Wireless Display (WiDi) capable laptop or tablet (with the specs mentioned here) from Windows 7 to Windows 8 Consumer Preview, then you probably stopped being able to enjoy WiDi.

The official support for WiDi on Windows 8 will come with the Intel WiDi software v3.5, and the Intel WiFi driver v15.5. These will follow Microsoft’s requirement that all pairing with external devices is done using their new WHQL certification process, from the Devices menu as seen below:



Until this happens, you could follow the steps below to make it work.This is not an officially supported procedure by Intel or Microsoft, and should only be considered for testing purposes until the official and correct method, drivers, software, and support becomes available.

1. Make sure that your WiDi 2.0 adapter has the latest firmware which presently is 3.1.29.0. If you need to update, do so from a working Windows 7 system. We tested this on the following adapters:

    • DLink DHD131

    • Netgear PTV2000

    • Belkin F7D4501



2. On Windows 8, download and install the Beta Intel HD 3000/2000 Graphics driver for Windows 8 v9.17.10.2729:

    • 32-bit version: here

    • 64-bit version: here



3. On Windows 8, download and install the Intel® PROSet Wirless WiFi Software & Drivers incl. Intel® My WiFi Technology v15.1.1:

    • 32-bit version: here

    • 64-bit version: here
      Important Note: When you install this package, make sure to select “Custom Install”, and choose to install “My WiFi Technology”)



4. On Windows 8, download and install the Intel® Wireless Display Software 3.0.13.0:

    • 32-bit and 64-bit versions here
      Important Note: Please use this specific version! Using the newest version of the Wireless Display Software (which presently is 3.1.29.0) does not work.



With these three components, WiDi on Windows 8 should become possible again with almost the same behavior known on Windows 7



Some few comments on our personal experience of using WiDi on Windows 8 on the Samsung Series 7 Slate so far:

    • Once WiDi is connected, the tablet resolution might go down to a level which prevents metro apps from launching. If this happens, just manually set it back to 1366 x 768

    • The “duplicate” display mode duplicates everything you see on your laptop or tablet to the external screen.

    • The audio always comes out from the external screen, whatever the app. And 5.1 audio works without any problems, and so does 1080p Full HD videos, and even Adobe Flash-based Youtube videos.

    • The “extended” mode behaves just like when using an HDMI cable on Windows 8. The metro interface remains on your laptop/tablet and desktop is extended on your screen.



We really have to stress again that the procedure above uses older or Beta versions of existing Intel drivers and software. So follow these instructions at your own risk! Again, the official support for WiDi on Win8 will come with WiDi v3.5, and WiFi v15.5, which will follow Microsoft’s requirements.
