I have this same issue.

MacBook Pro M1pro + D6000 connected 3 monitors - all 3 monitors is working (two displayport and one HDMI in displayport alt mode / passthru.
MacBook Air M4 + D6000 connected 3 monitors = only displayport monitors working

The displayport passthru itself does not use displaylink technology that I know of.
I think the key difference here is the M4 uses displayport 1.4 while the M1 uses displayport 1.2
I dont know what version is used by the D6000 but I suspect it has to do with the M4 handling two displayport streams whereas the M1 only has one.

Hi ericslaw,

Please make sure to update macOS to 15.7.x or newer.

PS. D6000 DisplayPort ports are driven by DisplayLink. The only Alt-Mode port is HDMI.

Regards,
Szymon
