SmartAVI SM-DPN-4D-S (4-Port Dual-Head DisplayPort KVM Switch / $700.52) Review
SmartAVI SM-DPN-4D-S 4-port dual-head DisplayPort 4K60 KVM switch USB audio
The DisplayPort sibling to SmartAVI's SM-UHN-4D-S, giving dual-monitor DP workstations four-way switching at full 4K60 per head plus USB and audio in one pushbutton unit.
DisplayPort Dual-Head, No Compromises
For desks standardized on DisplayPort rather than HDMI, the SM-DPN-4D-S delivers the same dual-head 4K60 capability without needing an HDMI adapter, keeping DP's native multi-stream advantages intact.
Comparison to Alternatives
It's positioned directly below SmartAVI's already-cataloged SM-DPN-4Q-S (quad-head) for buyers who only need two monitors per system, and it competes with Adder's AV4PRO-DP on price while adding true dual-head output the AV4PRO-DP lacks.
