    Connecting via legacy USB-A hosts provides video and data but no Power Delivery — a separate power splitter (K38310) is required for laptop charging in that scenario. DisplayLink lets MacBooks with M1/M2/M3 chips drive two external monitors, but requires installing and running Synaptics DockWorks.
