StarTech SV431DPUA2 (DisplayPort / 4 Computers / 4K@60Hz / USB 2.0 Hub / ~$462) Review
The StarTech SV431DPUA2 is a 4-port DisplayPort 1.2 KVM switch with single-display 4K@60Hz video, a USB 2.0 hub, and audio switching, priced around $462.
This sits between the budget 2-port DP switches and the pricier dual-monitor SV431DPDDUA2 — 4 computers, one 4K60 display, USB 2.0 rather than 3.0 for the hub. If your peripherals need faster transfer speeds, that's the tradeoff to weigh against StarTech's USB 3.0 4-port models. Versus the ATEN CS1944Dm — a similar 4-port DP 4K60 switch, comparably priced with similar switching options. Versus StarTech's own SV231DPU34K — half the ports but adds USB 3.0 and HDCP 2.2 for less money if 2 computers is enough.
Single-Display 4K60 Across 4 Machines
One DisplayPort output drives a single 4K@60Hz monitor while switching cleanly between 4 connected computers via front-panel buttons or hotkeys, with auto-scan cycling built in.
USB 2.0 Hub, Not 3.0
The integrated hub runs at USB 2.0 speeds rather than 3.0, which matters if you're routing high-speed external storage through the switch rather than just keyboard, mouse, and low-bandwidth peripherals.
