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. Match host/console video ports, host count, monitor count and EDID/USB requirements. A KVM extender is not automatically a standalone multi-computer KVM switch. Secure models require exact security/certification documents; no new certification is asserted here.
