DisplayLinkUserAgent
DisplayLinkUserAgent is a system utility that powers DisplayLink Manager, Elgato's display adapter and multi-screen extension software. It handles the low-level communication between DisplayLink-based external displays, Elgato Prompters, and other compatible USB video adapters with the Mac operating system. The utility runs continuously in the background to manage video output, scaling, and refresh-rate negotiation for external displays connected via DisplayLink technology. It is typically not launched directly by users but runs automatically as part of the DisplayLink Manager ecosystem.
AI Recommendation
1 suggestionDisplayLinkUserAgent is shipping as a Universal Binary that includes native ARM64 code for Apple Silicon, so your system already has native support built in. However, the full DisplayLink Manager application and its installer may still be packaging or defaulting to the Intel build in some configurations. If you are still running an older version of DisplayLink Manager, update it to the latest release from the vendor's website or the Mac App Store — this will ensure all components, including DisplayLinkUserAgent, are on the current native build. The fact that users are explicitly invoking the native ARM64 path (as documented in the community) suggests the native code exists but may not be the default launch path in all versions. Check for updates within DisplayLink Manager itself, or download the current installer directly from the vendor to ensure you are on the latest build with full native support.
