StarTech SV431DD2DU3A (DVI / 4 Computers / Dual Monitor / USB 3.0 Hub / ~$311) Review
The StarTech SV431DD2DU3A is a 4-port dual-monitor DVI KVM switch with a built-in USB 3.0 hub and separate stereo audio/mic switching, priced around $311.
This one's for buyers still running DVI displays and want dual-monitor switching without moving to DisplayPort or HDMI hardware — a shrinking but real segment, especially in older office and lab equipment refreshes. Auto-scan and buzzer confirmation round out the control options. Versus the ATEN CS1642 — a similar 4-port dual-DVI KVM at a comparable price, close on features. Versus StarTech's own SV431DHD4KU — moves to HDMI with 4K support if your hardware has since been upgraded.
Dual-Monitor DVI in a Shrinking Category
Two single-link DVI-D outputs switch together across 4 computers, a fit for offices and labs still standardized on DVI displays rather than newer digital standards.
USB 3.0 Hub and Separate Audio
A 2-port USB 3.0 hub handles peripheral sharing at full speed, and stereo audio plus microphone route independently per computer rather than sharing one analog pair.
Comparison to Alternatives
