Here’s what happens: when I connect two monitors—one via USB-C and one via HDMI—they both display the exact same image, and macOS only detects one external display. However, if I connect them individually, everything works fine.
I've also tested this both with and without the DisplayLink software installed, and the behavior is exactly the same.
My question is:
Is this expected behavior? Is it not possible to use USB-C and HDMI outputs simultaneously for extended displays on the UD22 when using a MacBook, and should I be using DisplayPort instead?
Thanks in advance for your help!

I had the same problem, understood the dock used an incompatible bus, and solved it by buying a Pulgable USBC-6950M (Plugable USB C to HDMI Adapter, Dual Monitor 4K 60Hz for Apple Mac M1/M2/M3, DisplayLink Multiple Displays for Thunderbolt MacBook or iMac) from Amazon.
My displays work fine now, but the DisplayLink software is still really buggy and gives unexpected behaviour. Downgrading drivers has helped.
