Usb c to displayport stopped working

[Mmicko8]

A couple weeks ago my laptop (envy 13-ah0100nd) was still able to project an image to my monitor using an usb c to displayport dongle, but now it suddenly stopped working. I've bought another adapter thinking my previous one broke but it didn't fix anything. When i plug in the dongle i get the error message: 'display connection might be limited'. The only notable change was that i updated windows and the BIOS. Would installing the previous versions fix it?

edit: I've also tried updating the display drivers for windows 1803.

Hi! @Mmicko8, Welcome to HP forums.

I understand the USB-C to display port has stopped functioning on your PC.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Have you tried checking with different USB devices?

Please try the steps recommended below.

Update the device driver through Windows Update by doing the following:

Click Start
Select Settings
Click Updates & Security
Click Windows Update 
In the Windows Update settings window, click Check for Updates, and install all updates listed.

 
1. Open Device Manager.
2. Expand category “Universal Serial Bus controllers”.
3. Double-click the “USB Root Hub” device, and click the Power Management tab. (if there’s more than one USB Root Hub device, repeat these steps for each one.)
4. Turn off the Allow the computer to turn off this device to save power option, and click  OK button.

Disconnect all USB devices connected to the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
In Windows, search for and open Device Manager.
The Device Manager window opens.
Double-click Universal Serial Bus Controllers to expand the list.
Right-click the first USB Root Hub in the list, then select Uninstall.
Click OK to confirm.
Continue uninstalling all USB Root Hubs listed.
Close Device Manager and restart the computer.
If the USB device that is having problems came with software and it was not previously installed, install the software now, following the manufacturer instructions.
Reconnect the USB device that was having problems and test it to see if it works.

 
Open Device Manager (Right Click on Windows Logo and Click Device Manager).
Now find and expand Universal Serial Bus controllers. Now right click on USB drivers and click Uninstall. Do for all USB drivers one by one.
Now Restart your PC. The USB drivers are automatically re-install and solve the corrupted USB devices.
Right-click on the battery icon and click Power Options.
Click Change plan settings.
Now click Change advanced power settings.
Find and expand USB settings.
Expand USB selective suspend settings and Disable both On battery and Plugged in settings.

Try updating the BIOS and chipset drivers on your PC and check if it helps.
