Selection limits

Match the exact connector standards, host features, supported OS/driver requirements and power-supply version. Manufacturer maximum throughput, resolution/refresh and Power Delivery ratings are conditional limits, not a universal result. USB-C connector shape alone does not guarantee DisplayPort Alt Mode, USB4/Thunderbolt bandwidth or USB Power Delivery. DisplayLink models may need drivers; macOS MST behaviour can differ. Check the exact product notes and display configuration.
