SmartAVI SM-EDPN-4D-S Review

SmartAVI SM-EDPN-4D-S is a 4-port dual-head DisplayPort KVM switch with 4K at 60 Hz per head, 3 USB 2.0 hub ports, audio, hotkey and pushbutton switching, and EDID emulation.

The SM-EDPN-4D-S lets one keyboard, mouse and two DisplayPort monitors control four computers. Each head supports up to 3840x2160 at 60 Hz, and switching works from the front-panel pushbutton or by hotkey. It has 3 USB 2.0 hub ports and audio support, and EDID emulation with a fixed EDID helps computers keep their display layout when you switch away. It is aimed at desks with two DisplayPort monitors. The limits are USB 2.0 speed on the hub, no USB-C Power Delivery and only two displays per computer.

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 costs less for desks that only need two monitors.
