SmartAVI SM-DVN-4D-S Review

SmartAVI SM-DVN-4D-S 4-port dual monitor DVI-D KVM switch with USB, two displays per computer, multi-monitor workstation switch, digital video KVM

For anyone who's standardized on a two-monitor desk, this switches both displays together across four computers with one button, so switching machines never leaves one monitor stuck on the wrong source.

Synchronized Dual-Monitor Switching

Both DVI-D outputs switch as a matched pair, avoiding the common annoyance of single-display KVMs where a second monitor has to be switched separately or left connected directly to one machine.

Digital-Only Trade-off

DVI-D drops analog VGA compatibility that DVI-I switches like the SM-DVN-4S retain, fine for all-digital modern hardware, a dealbreaker for legacy VGA equipment.

Comparison to Alternatives

For single-monitor setups at the same 4-port count with audio support, the SM-DVN-4S is cheaper. SmartAVI's SM-DVN-4Q-S goes further with quad dual-link DVI-D outputs for four-monitor desks. IOGEAR's GCS1924 offers dual-view DisplayPort switching at 4 ports for DisplayPort-based workstations.
