Avocent SC740-001 4-port dual-monitor DVI USB KVM switch

Four-Port Dual-Monitor KVM Switch

The Avocent SC740-001 is a SwitchView KVM switch designed for operators who need to control four separate computers from a single dual-monitor console. It supports DVI-I Dual-Link video and USB peripheral sharing across all connected systems. This unit suits command centres, trading desks or test labs where simultaneous visibility of two displays per computer is required. It provides a consolidated control point without software dependencies.

External Power Supply and Silent Operation

The switch draws power from an external 100 V AC to 240 V AC adapter, removing the need for an internal fan and keeping the chassis completely silent during operation. Heat dissipation is handled passively through the metal enclosure, so the unit adds no audible noise to a quiet control room. Power consumption remains low because the device only routes video and USB signals without active processing. This design simplifies rack or desk placement where noise is a concern.

Metal Chassis with Dense Rear Connectivity

A compact metal enclosure measuring 2.50" x 10.40" x 7.30" houses ten DVI-I Dual-Link female ports and six USB Type B female ports, all oriented toward the rear for clean cable management. The weight of 4 lbs gives the unit a stable footprint that resists shifting when cables are inserted or removed. Front-panel push buttons provide tactile port selection without requiring software or hot-key sequences. The dense port layout demands careful cable routing but keeps all connections accessible from one side.
