A technology explainer outlines how USB-C to HDMI adapters work, noting that video output depends on a USB-C port supporting DisplayPort Alternate Mode or Thunderbolt, a fully-featured cable capable of carrying video signals, and an adapter with a chip to convert the signal into HDMI. It notes that DisplayPort 1.4 supports up to 8K at 60Hz while DisplayPort 1.2 tops out at 4K at 60Hz, and that basic charging cables cannot transmit video at all.

DVI-D and DVI-I cables can connect to HDMI ports using a passive adapter because both standards share the same digital video protocol, requiring no conversion chip or external power. DVI-A, an analog variant, is incompatible without active conversion, but it was rarely used. HDMI and DisplayPort remain the preferred modern standards, with HDMI 2.2 supporting resolutions up to 16K and DisplayPort 2.1b enabling daisy-chained multi-monitor setups.

Monitors with built-in USB hubs use two types of ports: an upstream port that links the monitor to a computer, and downstream ports where peripherals like keyboards or drives connect. If a monitor's video signal runs over HDMI or DisplayPort, those cables don't carry USB data, so a separate USB upstream cable is required for the hub's downstream ports to function. USB-C can eliminate that extra cable when the monitor and cable support DisplayPort Alt Mode and USB Power Delivery.

USB-C video capability depends on DisplayPort Alternate Mode, a feature that lets a single cable carry both data and display signals, but it requires the device, cable, and monitor to all support it. Older USB 3.1/3.2 devices may or may not include this support depending on the manufacturer, while USB4 and all Thunderbolt 3-5 connections guarantee it.
