SmartAVI SM-DPN-4S-S (4-Port Single-Head DisplayPort KVM Switch / $427.79, was $549.00) Review

SmartAVI SM-DPN-4S-S 4-port single-head DisplayPort KVM switch discount

The single-monitor member of SmartAVI's 4-port DPN family, discounted about 22% from $549, for desks that need four DisplayPort sources but only one screen.

Four Systems, One Monitor, No Extras

The SM-DPN-4S-S strips SmartAVI's 4-port DPN switch down to single-head operation, saving over $270 versus the dual-head SM-DPN-4D-S for desks that don't need a second monitor.

Comparison to Alternatives

Against ATEN's CS1924A and CS1944DP, the SM-DPN-4S-S competes directly in the single-head 4-port DisplayPort niche at a similar discounted price point; the deciding factor is usually current promotions and USB hub port count. Against its own SM-DPN-4D-S sibling, the 4S-S is the right pick whenever dual-head isn't needed.
