SmartAVI SM-EDPN-4Q-S Review

SmartAVI SM-EDPN-4Q-S 4-port quad-head DisplayPort KVM switch

Brings full quad-monitor DisplayPort switching to a 4-system desk, sized between SmartAVI's already-cataloged SM-DPN-4Q-S and the larger 8-port SM-EDPN-8Q-S.

Quad-Monitor Switching for Four Systems

Financial and engineering desks running four monitors per workstation get full quad-head DisplayPort switching among four source computers here, at a meaningful discount from list price.

Comparison to Alternatives

Against SmartAVI's already-cataloged SM-DPN-4Q-S, the EDPN designation reflects an enhanced/extended feature set in the same 4-port quad-head niche; compare current specs and price closely between the two. Against the 8-port SM-EDPN-8Q-S in this batch, the 4Q costs less for desks that don't need eight sources.
