SmartAVI SM-DVN-4S Review

SmartAVI SM-DVN-4S 4-port DVI-I dual link KVM switch with audio and USB, single monitor desktop KVM, 2560x1600 resolution, office workstation switch

A straightforward desktop KVM for someone running four computers off one monitor, keyboard, mouse and speaker set, dual-link DVI pushes resolution up to 2560x1600, well past what a basic single-link switch can drive.

Dual-Link DVI Matters at High Resolution

Single-link DVI switches cap out around 1920x1200; the dual-link support here lets a single 2560x1600 monitor run at native resolution across all four connected machines.

Everyday Multi-PC Desktop Use

Developers, editors, and IT staff running a Windows box, a Linux box, and test machines side by side benefit from one-button switching without unplugging cables.

Comparison to Alternatives

For dual-monitor output instead of single, SmartAVI's SM-DVN-4D-S covers the same 4 ports. For 8 ports at a similar single-link feature set, the SM-DVN-8S scales up. IOGEAR's GCS1924 is a DisplayPort-based 4-port alternative with dual-view support if the workstation uses DisplayPort rather than DVI.
