Elitebook 830 G5 can't successfully make a Miracast connection

[nitto_hewpack]

Trying to connect to any of several Miracast receivers fails to successfully make a connection. The devices will display that a connection is being attempted then after some time they will show a message that they have failed.

Devices attempted to connect to: LG GRU510N Projector, Microsoft Wireless Display Adapter, and Microsoft Wireless Display Adapter 4k. The drivers for both Microsoft Adapters have been updated to the most recent driver. I have been able to connect and display using the two MS adapters using an LG V40 phone and a Lenovo Thinkpad that is not a company computer. So the adapters do seem to work generally.

The HP laptop is a work computer, most of the laptops we have are the same model.

Windows 10 Pro - Version 1903 - Build 18362.1256

I also tried with a coworker's laptop which has Windows version 20H2 - build 19042.1706 and it had the same results.

Checks and fixes attempted:

Used the HP Support assistant to update these drivers on the laptop during troubleshooting:

DisplayLink Graphic Driver - sp113541.exe
HP E24d G4 FHD Docking Monitor Firmware - sp112053.exe

Tried downgrading to a driver with a fix for this issue:

I also tried downgrading to this version of the Intel Video Driver that is mentioned as being a fix for this issue with these laptops:

Checking Wi-Fi Direct

As I believe it uses Wi-Fi Direct as well, I tried the W10 hotspot from the settings and while a network was visible my phone would fail to connect with an error message to check the password and try again. Tried with the laptop connected to different networks, changing the hotspot password, and tried changing the band from any available to 2.4. All the same result. This lead me to try checking the drivers below, which seems like the hotspot is probably unrelated.

'NETSH WLAN show drivers' states that wireless display is supported by both the graphics and Wi-Fi drivers:

If anyone can't point me in a direction to figure out why this isn't working, it would be appreciated.

Use DxDiag to generate a report and save it to the Notepad app.

Do a search for MiraCast in the DxDiag log saved in the Notebook app.

If the search does not find Miracast, that means you will need to purchase a wifi/bluetooth adapter to plug into a USB port on the notebook  that will work with MiraCast.

For your desired MiraCast connection to work, you will need to disable the notebook's default adapter and use the new one that you have purchased and installed. 

See the URL below to find out where to purchase USB adapters that will work for the MiraCast connection that you desire between laptops and displays that you have proven to be MiraCast connection capable .

Thank you, Erico. Learned something new.

I just checked the dxDiag info and found Miracast in several places:

Some more info, I have previously tried connecting the laptop to another smart TV without success.

I mentioned this problem to a coworker who said they used to be able to connect to a smart TV in one of the conference rooms but that "IT updated something on their computer" and now they could not. However, they were still able to connect to their smart TV at home.

The IT update was probably when they update our anti-malware (Cybereason) and antivirus (McAfee) over the summer. They also use SCCM, which has "broken" some things in the past. Generally, by blocking access to Microsoft's Windows update servers.

[erico]

That means it is MiraCast capable.

Well, since it is a work computer you may be out of luck, unless the IT Department is pushed into coming up with a fix. 

You can check to see if you can temporarily disable the AntiMalware to verify that it is the issue.

If the IT dept. has disabled Microsoft Updates, except for those they push to your notebook, there isn't much you can do about it. 

It is good that you mentioned that. I don't recall your mentioning your notebook was a work machine in a previous post.

You can try my suggestion of using a dongle to see if that works. They aren't terribly expensive, depending on your budget.

Thanks for the help Erico, I'll see what luck I have with IT.

If you’re having trouble connecting to your wireless display or wireless dock, try the following to fix things:

Make sure your Windows 10 device supports Miracast. Here's how to check on your PC: Select the Start button, type Connect, and then select Connect from the list of results. In the Connect app, the text will tell you if your Windows 10 device supports it. To check on your Windows 10 phone, on Start , swipe over to the All apps list, and look for Continuum . If Continuum appears in the All apps list, your Windows 10 phone supports Miracast.

Make sure Wi-Fi is turned on. To do this on your PC, select the Network ( or ) icon at the far right of the taskbar, and then check the Wi-Fi quick action. On your Windows 10 phone, swipe down from the top of your screen to open action center, and then check the Wi-Fi quick action.

Make sure the display supports Miracast and verify it's turned on. If your wireless display doesn't, you’ll need a Miracast adapter (sometimes called a dongle) that plugs into an HDMI port.

Make sure your device drivers are up to date and the latest firmware is installed for your wireless display, adapter, or dock. See the support info on the manufacturer's website for instructions, or search Microsoft Store for your manufacturer's app to help you.

Restart your PC or phone and the wireless display or dock.

Remove the wireless display or dock, and then reconnect it. To remove the device, open Settings , and then select Devices > Bluetooth & other devices . Select the wireless display, adapter, or dock, then select Remove device. After that, try reconnecting.

Greeting,

Rachel Gomez
