StarTech SV431DPU3A2 (DisplayPort / 4 Computers / 4K@30Hz / Rack-Mountable / ~$300) Review
The StarTech SV431DPU3A2 is a 4-port DisplayPort KVM switch with 4K@30Hz support, a built-in USB 3.0 hub, audio support, and a rack-mountable chassis for ~$300.
StarTech designed this switch with server-room deployment in mind, including rack-mount ears in the box rather than as a separate purchase, which matters for IT teams standardizing equipment across a rack. 4K resolution caps at 30Hz rather than 60Hz, a real tradeoff for video work but a non-issue for server console access, remote administration, and general desktop switching where motion smoothness isn't a priority. Versus the IOGEAR GCS1944 — that supports full 4K@60Hz and dual-view for a price premium, worth it for desktop multi-monitor work over server rack use. Versus the TESmart HKS801-E23 — that's HDMI-based with 8 ports, worth it for buyers needing more simultaneous machines.
