Default Video lagging when using PR09 with two QHD monitors

I have a Fujitsu PR09 port replicator. I have it connected through a USB-C cable to my laptop. It is connected to the power supply port on the PR09 so it provides power to my laptop. I have two QHD monitors connected using a DisplayPort cables.

The problem is that the video lags behind. A few hundred ms it appears. When typing this is not a big issue, but when dragging Windows, watching videos, etc. it is.

PCI Express Link State Power Management is switched off.

Sometimes the problem dissappears after disconnecting the USB-C cable and connecting it again. Only for the problem to appear again after a few minutes.

If Fujitsu is unable to assist you with their product, then you can report the issue directly to DisplayLink via the process described here --> https://support.displaylink.com/know...to-displaylink
