Plugable DisplayLink 4K and Macbook Pro continuously disconnects

I’m running macOS Sonoma 14.5 on a MacBook M2 Pro and I keep running into what seems to be random occurrences of the docking station disconnecting and reconnecting from the laptop for months. Initially I thought the issue was with using the DisplayLink software to enable dual monitors, so I removed the software and carried on with only a single monitor through HDMI on port #1 (ALT MODE). When the issue persisted with single monitor, I thought maybe the HDMI cable I was using could be the issue, so I switched to a DP 1.4 cable, and now that’s what I’m using as I’m connected to a Samsung G7 28’ (using a thunderbolt 4 cable - not the original cable, but the issues were the same with the original cables in my troubleshooting).

The docking station is connected to a power supply, and I read on a different thread that connecting it directly to the wall might solve the issue, but the issue still persists while plugged to the wall directly.

The occurrences seem to be fewer while on DP, but they still happen.

This does not happen with my Windows laptop (ThinkPad P1).

Is there anything else I can do to provide more information to this case? It’s frustrating to experience this considering the docking station is such a powerful tool.


Hi Caio,
