Hello,

We are currently using a large fleet of HP EliteBooks (primarily 845/855 G11 models) with HP USB-C G5 Docks. Since upgrading from the G9 to G11 generation, we have been experiencing a major issue with external monitor flickering.

 

Troubleshooting Steps Taken: 

- Replaced HDMI and DisplayPort cables
- Swapped the USB-C cable between the dock and laptop
- Tested with new monitore
- Exchanged for new docks
- Replaced motherboards and deployed brand-new notebooks

 

Despite these measures, the problem persists. The flickering causes screens to go black for a few seconds, occurring anywhere from every 2–3 minutes to just once a day

We would appreciate any insights or solutions to resolve this issue.

Hello.

 

Try updating the dock firmware to the latest version.

HP USB-C Dock G5 Software and Driver Downloads | HP® Support

 

The 1.0.23 version release last December contains several fixes, including this one:

Fixes an issue which causes HDMI monitors to blink unexpectedly

 

The updates are cumulative so the latest update contains all earlier fixes as well.

 

Check also the BIOS firmware package and graphics driver updates for your laptop as well, and all their release notes from your currently installed versions up to the latest version.
