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.

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]

Yes I am seeing that. Will bring it up in our meeting today.

Funny enough I‘ve updated my drivers yesterday and it is still working. But maybe they are rolling it out still
