StarTech SV431DPDDUA2 (DisplayPort / 4 Computers / Dual 4K@60Hz / USB Hub / ~$770) Review
The StarTech SV431DPDDUA2 is a 4-port dual-DisplayPort KVM switch that drives two 4K@60Hz monitors from any of 4 connected computers, with a USB hub and independent audio switching, for around $770.
This is a dual-monitor workstation switch, not a single-screen budget option — the price reflects driving two 4K displays simultaneously rather than one. If you only run a single monitor, this is overkill; StarTech's own single-display DP switches cost far less. Versus the ATEN CS1944 — a similar 4-port dual-4K DisplayPort KVM at a comparable price point, largely interchangeable on specs. Versus StarTech's own SV431DPUA2 — single-display only, worth it if you don't need the second monitor.
True Dual-4K Switching
Both DisplayPort outputs switch together across all 4 computers, so a dual-monitor desk setup stays intact no matter which machine is active — a real requirement for anyone running a two-screen workstation.
Independent Audio Per Computer
Each system gets its own 3.5mm speaker and microphone jacks on the input side, so audio switches cleanly along with video and USB rather than sharing a single analog path.
