Hello,
I have Asus G750JM with Broadcom AC adapter. I installed Win 8.1 Pro, with drivers from Asus website. I tried to add as a wireless display a LG Smart TV and a Netgear PTV3000. Both appear when searching for wireless displays but fail to connect after about 20 seconds.
Both the LG TV and the PTV3000 work with an Intel WIDI laptop, and with Android devices with Miracast.
Windows has the latest updates from Windows update.
I am at a loss, i don't know what to try anymore.
Thx in advance

hmscott the intel widi tool says "WiDi is ready to use".
However not even with the beta Nvidia and Intel Graphics drivers, the problem is the same.
If anyone tries to install the beta drivers create a restore point before. I had a few blue screens after installing the Nvidia beta driver.

The blue screen appeared at shutdown with a message regarding "power state" after installing the nvidia beta driver. That was all i could read before the auto restart.
I followed a lot of FAQ's including the one you suggested.
I don't think the problem is with the TV or PTV3000 as both work with other Miracast and WiDi devices. In fact the G750 is the only device that doesn't work. Thy both have latest firmwares installed. I think the problem is a driver (wireless adapter or graphics card) or win 8.1 itself.
Both the TV and the device show Connecting to laptop, but after about 20 sec they say Connection Unsuccessful. This behavior happens with any combination of drivers. I've also tried to disable firewall, antivirus, without success.
Does anybody know what Broadcom AC WiFi card the G750JM has? I've been trying to find other drivers for this card without any success.
I was also wondering does Miracast work for others with 2014 G750's?

In Win 8.1 Intel's WiDi does not work anymore, because Miracast is built-in in Windows. Intel has disabled WIDI in win 8.1.
Requirements for Miracast in Win 8.1 are:
- wireless adapter with NDIS 6.3 driver (virtual WIFI and WIFI Direct needed). You can see that by running Get-NetAdapter | Select Name, NdisVersion in powershell. Broadcom AC is NDIS 6.40
- graphics adapter wth WDDM 1.3 driver (win 8.1 only driver). Both Nvidia and Intel have WDDM 1.3 drivers, but i think Nvidia doesn't have yet full suport for Miracast.
The "add a wireless display" options in the Project Charm should appear only when all the above conditions are met. On a older laptop with older NDIS version of the wifi card the option never shows up.
I think the only solution for now is to wait.
I am tempted to try to install win 7 on the system only to check if widi works 🙂
PS: The dongle you mention is for the TV, in case your TV does not know Miracast or WIDI. Mine knows both, and i tested it with both with other devices and works well. The other device i have Netgear PTV3000 i use on a TV which does not have WIDI or Miracast and again works well with other devices.
