StarTech SV231DPU2 (DisplayPort / 2 Computers / 4K@30Hz / USB 2.0 Hub / Discontinued) Review
The StarTech SV231DPU2 is a 2-port DisplayPort KVM switch with a built-in USB 2.0 hub, supporting 4K video at 30Hz (SST), bus-powered with no external adapter needed.
This is StarTech's earlier-generation DP switch, since discontinued at most retailers in favor of the newer SV231DPU34K, but it's still floating around at closeout pricing and worth knowing about if you find one — 4K works, just capped at 30Hz rather than 60Hz, and the hub is USB 2.0 rather than 3.0. Versus StarTech's own SV231DPU34K — the direct successor, worth paying more for if you need 60Hz or USB 3.0 speeds. Versus the IOGEAR GCS932DP — a similar older-generation 2-port DP switch at a comparable spec level.
Bus-Powered, No Adapter Needed
Power draws entirely from the connected computers' USB ports, so there's no wall adapter to find room for — convenient for a compact desk setup, though it means both computers need to be powered on for full functionality.
4K at 30Hz, USB 2.0 Hub
Video resolution reaches 4K in single-stream mode but tops out at 30Hz, and the peripheral hub runs at USB 2.0 speeds — both since superseded by StarTech's newer SV231DPU34K.
Comparison to Alternatives
