SmartAVI SM-EDPN-4D-S (4-Port Dual-Head DisplayPort KVM Switch / $856.36, was $1099.00) Review
SmartAVI SM-EDPN-4D-S 4-port dual-head DisplayPort KVM switch discount
The dual-head member of SmartAVI's EDPN 4-port family, discounted about 22% from $1099, sized between the SM-DPN-4D-S and the quad-head SM-EDPN-4Q-S.
Enhanced Dual-Head DisplayPort Switching
The SM-EDPN-4D-S covers dual-monitor DisplayPort switching across four systems with the EDPN line's extended feature set, at a meaningfully lower price than the quad-head SM-EDPN-4Q-S.
Comparison to Alternatives
Against the standard SM-DPN-4D-S already in this catalog, the EDPN model likely adds refinements reflected in the higher list price before discount; compare specs closely. Against the SM-EDPN-4Q-S, the 4D-S saves over $300 for desks that only need two monitors.
