Screens via docking station is detected, but doesn't display anything

Anonymous

I got my new work pc (HP ZBook Fury 16 G10 Mobile Workstation - with Windows 11) and docking station (HP USB-C G5) last friday.

I have two Dell Ultrawide 34" screens connected to the docking station via mini displayport to displayport.

First time I plugged it in, it worked perfectly. However, when I unplugged it and attended a meeting, the screens didn't display anything when I plugged it back in. When the lid is open, I can see that the screens are detected but not displaying anything.

Have been in touch with our own IT-department and we've updated every driver you could think of, both on the pc and docking station. Nothing has worked. It seems like the only way to make the screens display anything again is by restarting the pc, and while that is happening plugging the screens and docking station back in. Problem is the same things happen again when i unplug and plug it back in.

Several of my colleagues (who have Windows 10) have tried to plug it in, and none of them have had the same problem. So I can only assume that it's Windows 11 that's causing this.

Any solution as to what I can do to fix this?

Hello Andreas,

Good to see you in Microsoft Community.

Firstly, could you let me know the specific system version? You can check it by pressing the Win key + R key, and typing "winver", then press Enter, please take a screenshot/photo of it, and only send the relevant information without PII in the next reply.

Have you tried using Win + P to adjust the Extended Display Mode after you've connected two external monitors again?

To change what shows on your displays, press Windows logo key + P. Here's what you can choose.

If you want to	Choose
See things on one display only.	PC screen only
See the same thing on all your displays.	Duplicate
See your desktop across multiple screens. When you have displays extended, you can move items between the two screens.	Extend
See everything on the second display only.	Second screen only

If possible, please do the following tests to further confirm whether it's the problem of the system itself or the problem of the monitors.

Connect your monitors to your colleagues’ Windows 10 computer and see if it works fine.
Connect your colleagues’ monitors to your Windows 11 computer to see if it works.

Or you can follow the steps below to remove the configure information of the monitors after unplugging the monitors, then reboot to reconnect again.

Open the Registry Editor by pressing WIN + R and typing "regedit". Then navigate to
```
 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
```
and locate the following three folders: Configuration, Connectivity, and ScaleFactors. You can directly delete these three folders.
Afterward, reconnect your external display by unplugging and plugging it back in, and check the results. Disclaimer*: Generally, modifying registry subkeys or workgroups is intended for advanced users, administrators, and IT Professionals. It can help fix some problems,* however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows (microsoft.com) to view the article.

If anything is unclear, please do not hesitate to let me know.
