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. Video conversion is directional unless the exact manufacturer specification explicitly states otherwise. USB-C video adapters require the stated video-capable host mode; display and source capabilities must match.
