Miracast clearly supported but connection fails

[ChrisWNY]

Stumped on this one...

When attempting to connect to a wireless display (via Miracast) the connection fails without an error code. This happens when attempting to connect to a Roku 4 as well as the Anyview Cast on my brand new Sharp Aquos 4K HDTV. I have another Lenovo T430 running Windows 10 and it doesn't have any issues connecting to the Roku or the HDTV, so I know the problem isn't with the Roku or HDTV.

Within the activity center as well as the Settings area, the wireless display devices are recognized and found without problems. When I choose to connect, the TV and the Roku device recognize that the 17-ar050wm is attempting to connect to project its display, but after a few seconds it just disconnects with no error message. Nothing in the Windows event log of note, no errors generated. I'm running the latest AMD Radeon R5 drivers and Windows 10 is updated to the latest patches, all chipset drivers are also up-to-date (via HP Support Assistant). I've exhausted troubleshooting steps.

Any ideas as to why a brand new laptop wouldn't be able to connect to a brand new HDTV via Miracast (Wireless Display)? This seems to be a problem from 2013 and not 2018...

Thank you for posting on HP Forums, MKazi is at your service. 

I came across your post and would like to help. 

I understand that you're facing difficulty to get the wireless display work from your HP Pavilion - 17-ar050wm laptop. This happens when attempting to connect to a Roku 4 as well as the Anyview Cast on my brand new Sharp Aquos 4K HDTV. Fabulous analysis. Spectacular diagnosis of the issue before posting. Kudos to you for that. You've done a remarkable job performing the steps. 

During my research, I came across the following information and it should make the Miracast to work:

• Verify that your computer is connected to WiFi.

• Restart your computer. Then restart the wireless display and adapter. If using an adapter, remove the adapter from the TV or monitor, restart your device, reinsert the wireless display adapter in the TV or monitor, and attempt to display again.

• If you are using a wireless display adapter, set the video source to the correct HDMI port (the one that the wireless adapter is connected to). To do this, check the video source settings on your HDTV, monitor, or projects. For instructions, check the information that came with your device or go to the manufacturer's website.

• If the adapter didn’t connect, open the Action Center, click All Settings, click Devices, and then click Connected Devices. Click Add a device, and then select the wireless display or wireless display adapter.

I sincerely hope this fixes the issue. Let me know how it goes. 

All the best! 🙂

Thanks for the reply - I was finally able to get my 17-ar050wm to connect to a wireless display via my Roku. I had to do the following:

1. Download and install latest Intel ProSet wireless drivers for Windows 10 x64

2. After installing Intel ProSet drivers, I had to re-run the installer, select "modify", then allow it to install the extensions (which included the wireless display extension)

3. I then reset Windows firewall to default (this was odd because when I completely disabled the firewall I still was NOT able to connect to a wireless display...the problem may have been a combination of a firewall and a driver issue)

4. Open Windows firewall and check the public/private ALLOW rules for Wireless Display so it's enabled

Once I completed the above steps, wireless display started working. Just wanted to post this info to help others resolve their own Miracast issues. Miracast is flaky and it seems that HP doesn't push the latest drivers through HP Support Assistant.
