System Setup:

MacBook Air (M1) running macOS 15.3
Two docking stations: One from HP and another from Accell/DisplayLink
Two HP E223 monitors
I’ve installed the latest DisplayLink app, and it recognizes the two monitors in the software. However, when I go to System Settings > Displays on my MacBook, it only shows the built-in display and one HP E223 monitor. Despite holding the Option key to force detection, the second monitor doesn't appear in the display settings.

Both monitors are physically connected to the docking station and are displaying mirrored content, but I want to set them up in extended mode, so they function as independent displays. No matter what combinations I try, I can’t seem to get them to work properly.

Any idea on what might be causing the issue, or steps I can take to get both monitors working as separate displays?
