SmartAVI SM-MST-2Q (2-Port Quad-Head Multi-Stream KVM Switch, Discontinued / $513.51) Review
SmartAVI SM-MST-2Q discontinued 2-port quad-head multi-stream KVM switch clearance
A discontinued two-computer, quad-monitor MST switch from SmartAVI's legacy lineup, priced for clearance but without manufacturer support going forward.
Two Systems, Four Monitors, Legacy Design
The SM-MST-2Q packed quad-head DisplayPort MST switching into a two-source unit, but like the rest of the MST line has been superseded and discontinued by SmartAVI.
Comparison to Alternatives
SmartAVI's EDPN and DPN lines don't currently offer an exact 2-port quad-head replacement in this catalog, making the SM-MST-2Q a niche clearance option for buyers who specifically need two-system quad-monitor switching and accept the lack of support.
