SmartAVI SM-MST-2D Review

SmartAVI SM-MST-2D discontinued 2-port dual-head multi-stream KVM switch clearance budget

The smallest and least expensive of SmartAVI's discontinued MST switches, offering dual-head switching for two computers at a clearance price with no ongoing support.

Entry-Level Legacy MST Switch

The SM-MST-2D was SmartAVI's budget dual-head MST option for two computers; it has been discontinued alongside the rest of the MST family in favor of the DPN line's native architecture.

Comparison to Alternatives

SmartAVI's SM-DPN-2D-S covers the identical two-port dual-head niche with active manufacturer support at a comparable discounted price, making it the clearly better choice for anything beyond a clearance-priced spare.
