Issue with HP Probook 450 G5 connecting via USB-C docking station to external monitors

HP Recommended
HP ProbooK 450 G5 & 1MK33ET
Microsoft Windows 10 (64-bit)



I have bought the following configuration:


- HP ProBook 450 G5 i5-8250U 15.6FHD 8GB 1DDR4 256GB SSD 

- HP USB-C universal dock (1MK33ET)

- 2 external monitors HP E243  elite display (1FH47AA)


( the 2 external monitors are connected with DisplayPort connectors/cables)


Sometimes up to 10 times a day artifacts appear (vertical stripes) on both external monitors (never on the laptop itself).

Unplugging an plugging the power of the docking fixes the issue.

When conncecting one monitor it seems to work without this problem.

However, as you can understand, this is anoying.


The laptop have been deployed a few weeks ago with all latest drivers and BIOS updates.

I was looking for a firmware update for the docking, but could not find one on the HP site.

Could anyone give me some tips or suggestions on how to solve this issue?


Thx in advance!
