I am in the process of "shaving the cord" and have installed a Microsoft Wireless Display Adapter on my TV for streaming content from my computers.
I have two computers.
One, a Dell Inspiron 7373 running Win 10, with a built-in Intel UHD Graphics 620 display adapter and an Intel Dual Band Wireless-AC 7265 network adapter.
One, a Dell XPS 8900 running Win 10, with a built-in Intel HD Graphics 530 display adapter, an NVIDIA GeForce GTX 745 display adapter, and Dell Wireless 1801 802.11bgn network adapter.
The Inspiron connects to the Microsoft Wireless Display Adapter effortlessly, with no video or audio issues.
Using the Intel HD Graphics 530 display adapter, the XPS can "see" the adapter, but when I click on it to connect to it, both the adapter and the TV look like they are trying to connect, but then suddenly disconnect. The 8900's desktop never appears on the TV. Using the NVIDIA GeForce GTX 745 display adapter, the XPS connects to the adapter just fine.
In Event Viewer, I am seeing the following critical errors after attempting to use the Intel HD Graphics 530 display adapter:
Critical 11/27/2018 12:14:14 PM Microsoft-Windows-DriverFrameworks-UserMode 10111 User-mode Driver problems.
The device MSDisplayAdapter_93 (location (unknown)) is offline due to a user-mode driver crash. Windows will attempt to restart the device 5 more times. Please contact the device manufacturer for more information about this problem.
Critical 11/27/2018 12:14:14 PM Microsoft-Windows-DriverFrameworks-UserMode 10110 User-mode Driver problems.
A problem has occurred with one or more user-mode drivers and the hosting process has been terminated. This may temporarily interrupt your ability to access the devices.
In Norton Security Online, I am seeing:
"Protecting your connection to a newly detected network on adapter \"Microsoft Wi-Fi Direct Virtual Adapter # 7
IP address has disappeared from adapter Microsoft Wi-Fi Direct Virtual Adapter # 7
Everywhere I've looked for answers they've been all about updating graphics and network adapter drivers. It's an Intel issue if the Intel components are supposed to support Miracast but somehow they don't.
And, if you want to get the latest HD530 driver, you can find it here:

Re-read my comment. If I can connect when using the NVIDIA graphics adapter, but not when using the Intel graphics adapter, the issue is not the wireless adapter.
So, you believe that the issue is with HD530 graphics, and not how Microsoft is interfacing with HD530 graphics, or the dell card, or the norton a/v?
Perhaps someone will be able to solve this mystery.
One question. In your dell 8900, do you have both the HD530 and the nvidia active at the same time? If so, remove the nvidia and try the HD530 by itself.
Again, re-read my comment. I indicated that I switched between adapters, i.e., disabled/disconnected one then the other. I also tried enabling/connecting both, but the combination seems to default to the Intel.
There could be an error in the dell bios, where the coexistence of both cards causes a problem.
It is a simple, easy test. Physically remove the nvidia card, and just use the Intel graphics, and do your wireless test.
Funny thing, for reasons as mysterious as the original issue, I was suddenly able to connect the XPS 8900 to the Microsoft Wireless Display Adapter. I have no idea who, what, when, where, why, or how. I can only presume that some driver update and/or some setting change enabled it.
