After updating to macOS Sequoia 15.4.x on a MacBook Pro (Apple Silicon), the DisplayLink adapter used in the docking station starts normally and both monitors are detected, but after ~30–90 seconds of operation, the secondary monitor loses signal ("No Monitor Snow Rider") even though DisplayLink Manager is still running. Unplugging and replugging the cable sometimes restores the signal, but only for a short time. This behavior is repeatable on two different docking/adapter models. Are there any new SystemDisplay modules or macOS APIs that could be conflicting with DisplayLink Manager after the update?
