Choosing the Right Adapter

Active vs Passive Adapters

Passive adapters simply rewire pin connections between compatible standards (e.g., DisplayPort to HDMI). Active adapters contain a conversion chip and are required when the source port does not natively output the target signal — for example, USB-C to VGA or USB-C to dual HDMI. Active adapters cost more but support broader compatibility.

USB-C vs Thunderbolt

USB-C adapters work with any USB-C port. Thunderbolt adapters require a Thunderbolt 3 or 4 port but deliver higher bandwidth — important for dual 4K displays, 10 Gigabit Ethernet, or PCIe storage. Check your laptop specs to know which port you have before buying.

Frequently Asked Questions

Will a USB-C to HDMI adapter support 4K?

Most StarTech USB-C to HDMI adapters support 4K at 30Hz or 60Hz depending on the model. Check the specific product specs for maximum resolution and refresh rate. Models with DisplayPort Alt Mode or Thunderbolt 3/4 support generally deliver 4K 60Hz.

Do StarTech network adapters work without drivers?

Many StarTech USB Ethernet adapters are natively supported by Windows 10/11, macOS, and Linux with no additional drivers. Check the product compatibility list for your operating system. PCIe network cards may require a driver download.
