DisplayLink only detects 2 out of 3 monitors while macOS still sees all displays

I’m using DisplayLink and I’m running into an issue with my monitors.

I have three external displays. Until recently, everything was working correctly. Now DisplayLink only detects two screens out of the three. Nothing in my setup has changed.

What’s confusing is that all three monitors are still detected in macOS Display settings, but DisplayLink only activates two of them, so the third one no longer works.

I’ve already checked cables and connections. From the macOS side, the displays are visible, but DisplayLink seems to ignore one screen.

This setup was working before, and the problem appeared without any clear change.
