What is the difference between a passive and active adapter?

A passive adapter relies on the computer or graphics card to convert the video signal, while an active adapter has built-in electronics to convert the signal from one video connection to another.

Passive adapters can work well when the computer or graphics card supports the required signal conversion. Active adapters provide broader compatibility and are often recommended when connecting different video standards, such as DisplayPort to HDMI.

If you are looking for an active adapter, you can view available options from VisionTek Active Adapters.

Important

• Passive adapters rely on the source device to convert the video signal.
• Active adapters convert the video signal within the adapter.
• Active adapters generally provide better compatibility with a wider range of devices.
• Video adapters are directional. A DisplayPort to HDMI adapter may not work when connected in the opposite direction.
• If you are unsure which adapter you need, check the video outputs on your computer or graphics card and the inputs on your monitor.
