Display are slow
 

Hi, I just purchased a UG69PD2-Pro dock to drive 2 Eizo 4K monitors via display port off my Macbook Pro M1 (with usb-c Cable).

I use it almost exclusively for photo editing (Lightroom and Photoshop) but the monitors seem so slow and are seriously dragging behind when I do edits.

I have the new Sonoma 14.1.1 software and the latest DisplayLink drivers off the website.
Any thoughts how to improve this?

Many thanks
Peter
