SmartAVI SM-EDPN-4S-S Review

SmartAVI SM-EDPN-4S-S 4-port single-head DisplayPort KVM switch

The entry point to SmartAVI's EDPN 4-port line, offering single-monitor DisplayPort switching across four computers.

Single-Monitor Simplicity, Four Systems

For desks that don't need dual or quad monitors, the SM-EDPN-4S-S delivers straightforward single-head DisplayPort switching across four systems at the lowest price point in the EDPN 4-port family.

Comparison to Alternatives

Against ATEN's CS1924A/CS1944DP, the SM-EDPN-4S-S competes directly in the single-head 4-port DisplayPort niche at a comparable discounted price. Against its own SM-EDPN-4D-S sibling, the 4S-S costs less when a second monitor isn't required.
