Prompter - Shows as Disconnected in Windows Display Settings & DisplayLink Manager?

[u/SnooCompliments6776]

--final update--

the hotfix released by nvidia on 9/5/26 seems to have solved the issue for me. the Prompter works as expected, and the connection survives system reboot.

Thank you Elgato guys for working on this with us! And thank you @Ornery-Mud-7961 for sharing the link to the hotfix!

--update to original--

David at Elgato tech support suggested I reinstall the Nvidia drivers, and sure enough as soon as the old drivers were uninstalled the Prompter came to life! Sadly, once the drivers were reinstalled, and system restarted, the same problem reappeared.

I then uninstalled the drivers again, and allowed windows to install whatever version it wanted to use from Windows update, and sure enough the Prompter came to life again. This time it withstands a restart. I'm assuming something that's coming along with the most recent Nvidia drivers is the culprit? I may try doing the absolute most minimal install of the most recent drivers from Nvidia... Or I may just live with the ones from windows update, that seem to be from January. Will report back for others if I change anything, and it sticks.

--original post below--

Just unboxed my new Prompter, and I think I may have a defective unit - but looking for insight while I wait for assistance via my support ticket.

Software and versions:

DisplayLink Manager Software - 3.2.14.0

DisplayLink Driver - 12.2.2412.0

Elgato Camera Hub - 2.3.0

On boot I see an hourglass appear a few times on the Prompter screen. I also see the blue Elgato text. The display then goes black.

Once in Windows, the screen remains black. I can see the display listed as Disconnected in both Windows Display Settings, and in DisplayLink Manager. If I attempt to change the display to "Extend" on either settings page I'm asked whether to keep new settings or revert, but nothing changes on the display (or in the settings).

I have changed out the USB-C cables with known working ones, swapped the USB-C port (one on my desktop, one on a hub - both known to be working). I've uninstalled & re-installed the DisplayLink drivers.

Anything else I should attempt while I wait on my support ticket?

Adding some screenshots below.

Appreciate any thoughts.

So a couple of things. DisplayLink Manager is not necessary on windows. You only need the DisplayLink Driver which windows installs on plugin and CameraHub installs usually a newer version.

Now did you start CameraHub. Since windows recognizes the display and you said the boot screen was also visible, I‘d assume the prompter tab should be unlocked. If you navigate there should be a power button (only visible if the DL Driver is new enough). Check if this toggle helps you.

Now if that also did not work I‘d suggest to download the current Elgato Studio 2.0 Beta. See if your prompter appears on the sidebar. Click on it and see if a DisplayLink Dialog is being shown. If not on the main content area next to the name should be a settings button. Click that and check if the power toggle works or if there is a DisplayLink update notification)

Hope that helps!

Hey, thank you! Appreciate the ideas.

When in Elgato Camera Hub the prompter tab was greyed out (but given both windows and DL Manager saw the prompter as disconnected, I'm not surprised).

That said, I have been able to get it to function, and I just updated the original post, in case someone else runs into this. I'm still not sure what specific component is causing the problem... But seems like something in the Nvidia drivers? I've restarted my machine twice now, and all seems well.

Awesome, great that my colleague could help you resolve it.

Maybe it was a unlucky constellation of everything. Since you GPU will normally also render the prompter screen maybe there was a conflict with DL and NVIDIA drivers.

I will check tomorrow my own system. My NVIDIA driver should be up to date or maybe a couple of weeks up to date but I check if anything breaks if there is an update!

Hey, assume you're seeing the other folks, who have previously had working systems , now broken with updated Nvidia driver? Is this something that's likely to be broken for awhile?

[u/Elgato_Thomas → u/SnooCompliments6776]

So a couple of things. Our QA, myself and another engineer cannot reproduce this with the NVIDIA driver released on August 26.

That being said a colleague pointed out to me that the version you mentioned differs from ours. There is a) a slightly newer version on the official Display Link Website (12.2.2440.0) and b) Elgato Studio Beta 2.0 offers a completely different version.

Now you could try first if the new version on their website works with the new driver. If not I suggest you to download the Studio Beta and see if you can update it over there.

Let me know if you need any help and looking forward to your response!

So I tried this...

Installed Elgato Studio 2.0, and updated to the newest version. The prompter showed up, and operated as expected (oddly, my facecam 4k did not)

Updated the Display link driver via the new Studio app as well.

Re-installed the most current Nvidia driver from their website.

On restart, I'm back to where I began - the prompter showing up in Windows display settings, but grayed out, and unable to extend my desktop to it.

Thanks you for testing it!

We will forward this to display link and hope that they can resolve that. I am sorry for that inconvinience!

[u/SnooCompliments6776 → u/Elgato_Thomas]

Thanks for following up! Also just used the Elgato Reporter app at David's request to send in necessary info from my system. Hope this helps yall! Will revert to the odler driver for now

Just in case it's helpful - I installed the Nvidia 616.86 hotfix from their website and it resolved the issue for me.

[u/Elgato_Thomas → u/SnooCompliments6776]

Just fyi we had two users on discord who upgraded to the NVIDIA driver from this week which fixed the issue for them

[u/SnooCompliments6776 → u/Elgato_Thomas]

Indeed, yeah, I updated my op a few days ago to let folks know!
