usb c to 4k hdmi adapter

USB‑C to HDMI adapters work with many USB‑C laptops, tablets and smartphones and with Windows, macOS, ChromeOS, Linux and Android. Compatibility depends on the host supporting video output over USB‑C, so confirm your device supports video over its USB‑C port before buying.

Many multiport USB‑C HDMI adapters include a USB‑C Power Delivery (PD) passthrough port and list support up to 100W. Actual supported wattage varies by model, so check the product listing to confirm the adapter’s PD wattage and whether it supports charging while in use.

Typical setup is plug‑and‑play: 1) Connect the adapter to your device’s USB‑C port, 2) plug an HDMI cable from the adapter to your display, 3) power the display and select the HDMI input. No drivers or external power are usually required, but the host must support video output over USB‑C.

Commonly a single connected display can reach 4K@60Hz, while using two displays from a dual‑HDMI adapter often limits each display to 4K@30Hz. Host hardware, DisplayPort mode and adapter design can further affect available refresh rates—check product specs.

Many adapters support 4K output up to 4K@60Hz for a single display. Splitter or dual‑output adapters commonly support 4K@30Hz per display, and some single‑port adapters may be limited to 4K@30Hz—always check the product specifications for exact support.

Many hubs include USB‑A and USB‑C data ports supporting up to 5 Gbps; some include a USB 2.0 port at up to 480 Mbps. Several adapters add SD and microSD slots that support UHS‑I speeds (up to 104 MB/s) and list card capacities up to 2 TB—check each product’s specs for exact speeds and supported capacities.

Listings show short cable lengths such as 0.2 ft and 0.6 ft, and some specify a 200 mm cable. One hub lists dimensions of 1.0 in (H) x 4.3 in (W) x 9.1 in (D). Sizing information is limited and varies by product, so check each product page for precise cable length and dimensions.
