Thank you for your post Alex,
I understand that you have questions in regards the Intel® Wireless Display.
Please note that this option comes available only if the OEM manufacturer enables the option and complies with all the hardware requirements from Intel®, the system needs to comply with a list of requirements that you can find under the following link:
If your system does not meet the requirements unfortunately the Intel® Wireless Display won’t work.
Also note that the wireless display feature needs to be enabled from factory for it to work also it needs to be advertized at the laptop by the OEM manufacturer, otherwise there is no way to activate or enable this option in your system.
I hope this helps
I'm with you Alex! My Toshiba Satellite 4200 is likewise supposed to support Widi and it did for a few months until I mistakenly upgraded to Win8.1 on some BAD advice from the OEM and OS providers. I have a NetGear Push2TV2000 that was working just fine until I recently updated to Win 8.1. This upgrade changes things so you can no longer use the Widi software AT ALL.
This update is supposed to provide an alternative through the Display settings. If you open your display controls and look to extend your display, you will see a link to "add a wireless display". Click that and your computer SHOULD detect and identify the Push2TV device, then it will provide an on-screen key to input that should complete the connection and start broadcasting the computer screen to the TV.
My computer even apparently completed the process successfully one time! I correctly input the code, but now and ever since, my computer no longer detects or recognizes the device! Hence I'm adding to this thread because I'm desperate for an answer and we share this similar pain point. Hopefully my advice above offers you another approach that might help.
As for my own frustration, there must be a way to get this working again, especially since it worked before, insofar as it's a knows issue, and because the upgrade specifically offers a solution to address it!
As victor said it, this option comes available only if the OEM manufacturer enables the option and complies with all the hardware requirements from Intel. It is important to mention that when changing the original operating system by a retail version, there may be special features that may not be available since the original operating system can be modified to work with your hardware.
I recommend you going to defaults in your system or contacting the manufacture for further assistance.
