SmartAVI SM-DVN-4Q-S (4-Port Quad Dual-Link DVI-D KVM with USB) Review

SmartAVI SM-DVN-4Q-S 4-port quad monitor dual-link DVI-D KVM switch with USB, four display workstation switch, 2560x1600 high resolution multi-monitor KVM

The heavyweight of SmartAVI's DVN line: four dual-link DVI-D outputs switching together across four computers, for trading floors and video-wall control rooms running four monitors per seat.

Built for Four-Monitor Workstations

Financial trading desks and surveillance/control-room seats increasingly run four monitors per operator; this switch is one of the few local KVMs that switches all four in perfect sync across multiple source PCs.

Dual-Link Resolution at Scale

Each of the four outputs supports dual-link DVI-D up to 2560x1600, so a high-resolution quad-monitor array doesn't get downgraded when this switch sits in the signal path.

Comparison to Alternatives

For dual-monitor rather than quad, the SM-DVN-4D-S covers the same 4 ports at roughly $350 less. For single-monitor use, the SM-DVN-4S is the budget option. Nothing else in this catalog matches quad-monitor synchronized switching — IOGEAR and ATEN's KVMs here top out at dual-view.
