Extron USBC-HDM/6 (part number 26-717-06) — a 6 ft (1.8 m) USB-C male to HDMI male adapter cable that puts a DisplayPort Alt Mode laptop onto an HDMI display at 4K/60.

Modern laptops present USB-C; most displays, switchers and recorders still present HDMI. This cable does the conversion inside the connector, so no dongle hangs off the source and nothing needs power. It carries 18 Gbps, which is what 4096x2160 at 60 Hz actually needs, and it passes EDID, HDCP and audio in both directions so the display negotiates properly rather than falling back to a safe mode. Six feet is the working length for a table or lectern to a nearby input plate.
