Keep four computers under direct control from one DisplayPort workstation without sacrificing image quality or peripheral access. The StarTech SV431DPUA2 is built for environments where precision matters, from medical imaging to technical operations that depend on crisp 4K output. With support for resolutions up to 4K at 60 Hz, it preserves detail on modern displays while maintaining a clean, centralized desk setup. This 4-port KVM switch also carries digital 7.1 HD audio and 3.5 mm analog audio, so operators can keep audio paths aligned with the active system. A built-in 2-port USB 2.0 hub extends shared access to essential peripherals, while front-panel push buttons and hotkey switching provide quick, repeatable control. Audible switch indication adds confirmation in busy workspaces. TAA compliance makes it a fit for procurement environments with sourcing requirements, and compatibility with PC and Mac systems broadens deployment options. For teams replacing multiple keyboards, mice, and monitors with a single control point, this model delivers the clarity and control expected in higher-value infrastructure purchases.
