Enabling Wireless Display (WiDi) on Windows 8 RTM

Hi everyone,

Windows 8 has just launched, so Intel just released the new WiDi software v3.5.40.0 to support Windows 8. Therefore, in order to enable WiDi officially on your Windows 8 device, follow the steps below:

1. Download the latest graphics driver for your Intel HD graphics from the following link. As of writing this message, the latest version is ( Choose x86 if you are running a 32-bit version of Windows 8, or x64 if you are running a 64-bit version of Windows 8: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily...

2. Download the latest Intel Wireless ProSet driver and software for Windows 8 from the following link. As of writing this message, the version is 15.5.6. Choose x86 if you are running a 32-bit version of Windows 8, or x64 if you are running a 64-bit version of Windows 8: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21999&lang=eng&wapkw=proset+15.5.6

3. Download the latest Intel WiDi Software v3.5.40.0 from the following link: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22016&ProdId=3227&lang=eng&OSVersion=Windows%208%2C%2064-bit*&DownloadType=Software%20Applications

4. After installing the WiDi software, run it and you should find your WiDi adapter. Connect to it, and it will show you a "Device Pairing" screen. Enter the 4-digit security code you see on your TV screen, and press continue.

5. The Windows "Add a device" screen will show up, asking you to "Choose a device or printer to add to this PC". Click on "IntelWiDiAdapter", and click Next.

6. A new Window will show asking you to "Enter the WPS PIN for your television". An 8-digit number may be already showing. Make sure the number is the same as the one you see on your television, and click Next.

7. The Intel WiDi software will take a bit of time the first time it connects to your WiDi adapter, and then will notify you that there is a firmware update. It will say that it wants to update your adapter to firmware v3.5.28.0. Click Update.

8. 7 files will be copied to your WiDi adapter, and your WiDi adapter will soon start updating itself and then restart.

9. After the adapter restarts after updating, and shows that it is ready to accept connections, connect to it again from the Intel WiDi software. The "Device Pairing" screen will show up again. Click continue.

10. The Windows "Add a device" screen will show up again, asking you to "Choose a device or printer to add to this PC". Click on the device that shows the name of your WiDi Adapter (if you haven’t changed this manually before, for NetGear WiDi adapters, this will probably be Living Room-PTV2000).

11. An 8-digit number will show on your television. Enter this number into the "Add a device" Window and click Next.

12. You will get connected to the WiDi adapter, and your computer's screen will be duplicated on the television, but the resolution might change and become lower. If this happens, right click on your desktop, and click on "screen resolution" and change your resolution to one that is appropriate for your television.

Attached in this blog is a video of me going through all these steps on my Ultrabook with an Intel Centrino Advanced-N 6235 card.

By the way, if you still have other computers running windows 7 and an older version of the WiDi software, you will still be able to connect it to the WiDi adapter and enjoy WiDi, even though the adapter was just upgraded to firmware v3.5.28.0

Hope to hear back from you guys about your experiences.

Enjoy WiDi on Windows 8! :)

ahahaha, i solved my "plattform not compatible issue" by enabling the laptop display. i only used my external 24" display until now. i guess the widi software then does not recognize the intel hd 4000 gfx because it is disabled.

I'm on a Lenovo V570 and also get the "platform is not compatible" error when trying to install All the other drivers appear to be up to date with the latest (graphics driver, Wireless ProSet 15.5.6, etc). I just can't get the WiDi software to install. Previous vercions have installed, but do not work. Versio installs, but when I run it, it immediately pops up an error, but not long enough for me to read and then it closes. Version installs, but shortly after running it, I get the error "Unable to start Intel My WiFi Technology.

Any help is appreciated!

FYI - I had tons of trouble, and simply uninstalling the pro-set and widi, and reinstalling the 15.3.50 drivers, then WiDi solved it. Currently looking at my PC screen on the TV :)

One thing, though: steps 5 through 12 never happened.. Never got prompted for adding a device, or had to enter any other string of numbers than the original 4 It asked me to update the firmware, but I told it no - I can do it later if necessary. I've read people having problems with the firmware update, and with all the trouble I've had, I'm not about to jump into more troubleshooting just for the sake of doing so.

Hi guys,

I think i know now the reason why some people get the "WiDiApp has stopped working" message. You are right, 15.5.6 might not work for every Intel wireless card that supports WiDi!

The right thing to do is to download the latest Intel Wireless proset driver and software for your card by going to the link below and selecting in step 1 "Wireless Networking", and in step 2, select either "Intel Centrino Wi-Fi Products" or "Intel WiMax Adapters" depending on your card type (most people will have a Centrino Product", and in step 3, choose your exact model.


The latest version that pops up when you follow this method is different for each Wireless adapter for some reason. For example, if you have the Intel Centrino Advanced-N 6230 card, then the latest correct version is v15.3.50, and if you have the Intel Centrino Advanced-N 6235 card, then the latest correct version is v15.5.6. If you try to install v15.5.6 on a system that uses an Advanced-N 6230 card, WiDi will not work correctly!

Sorry if I didn’t know or notice this before because I had my Samsung S7 tablet fitted with an Intel Centrino Advanced-N 6235 card just like the one in my ultrabook, so they both behaved identically. That’s why there were others that also had no problems with the Samsung S7.

I think even if v15.3.50 makes WiDi work with the 6230 card, it is still a workaround. That is why I believe they state in the release notes that 6230 is not supported under Windows 8. This is because this older version v15.3.50 of the proset driver/software doesn’t adhere to Windows 8's requirements pairing with external devices as described in the original post.

Can someone confirm?

Thank you again all for your patience, and for helping us debug these issues with graphics and Wi-Fi drivers.

I've been experiencing nothing but problems since upgrading to Windows 8.

I upgraded to windows 8 partly on the advice in this column.

Here is a post I;ve made over on the Intel forums detailing my experience thus far, can anyone suggest anything?

Anonymous - What is the method of getting it to work with the ProSet Drivers you listed?

Uninstall everything, and re-start the installation process in the same order using 15.3.50 instead of the 15.5.6?

For those with the Samsung 7, if you are getting the WiDiApp has stopped working - it appears to be related to the fact that the ProSet Drivers listed above (15.5.6) do not include a driver for the 6230 adapter and it fails with the inbox driver from Microsoft. I tried to use some of the other adapters listed in the .inf file from 15.5.6, but they appeared to work until I got the the point of connecting - then I would get the message that "This device is not compatible with WiDi on Windows 8". After some trial and error, I used the newly released ProSet drivers for Windows 8 (15.3.50) and was able to get them to work with the new Widi 3.5.40 software listed above.

15.3.50 - http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22005&lang=eng&OSVersion=Windows%208%2C%2064-bit*&DownloadType=%0A%09%09%09%09%09%09%09Software%20Applications%0A%09%09%09%09%09%09

Oddly enough in the release notes for 15.5.6, it states the 6230 is not supported under Windows 8. I'm scratching my head on this one, since Intel released a supported version on the same day in another package? Any thoughts on this rradi?

When I started to install windows 8 it said I would have to uninstall Intel wireless display that it wasn't compatible with windows 8. With your procedure do I uninstall WIDI, install Windows 8 and the install the WIDI drivers and software? Or do I install the Windows 8 WIDI drivers etc and then uninstall WIDI. Thanks for your help.

Thank you for your efforts and documentation! i confirm this exact process worked on my Samsung S7 tablet from //Build conference last year after changing the original Option card with a Intel Advanced-N 6235 card. Thanks!!

I also am getting the WiDiApp has stopped working" message and program failure after following your instructions to the letter. I am using a Samsung Slate 7 with windows 8 pro on it. Has this been successfully run on a Samsung slate series 7?

I take it back, it is not working. The Dell Release of the WiDi software is just a repacked older version which can be installed but it is not working.

I checked the logfile which is mentioned in the error message while installing the newest intel widi package (shortened):
