Dual-Link DVI KVM for two systems

The IOGEAR GCS1642 connects two computers to a shared dual-monitor console using Dual-Link DVI and USB. It supports resolutions up to 2560 x 1600 across both displays. Switching is handled by hotkeys, a front pushbutton, or a three-button USB mouse. The unit includes a 2.0 hub for peripheral sharing and separate audio jacks for speakers and microphone.

Fits a dual-head workstation with two PCs

Each computer requires two Dual-Link DVI outputs, one USB Type-B port, and audio connections to reach the switch. The console side provides two DVI inputs for monitors, two USB Type-A ports for keyboard and mouse, and audio jacks. A 5.3 V, 2.4 A power adapter is required for operation. The chassis measures 10.2" x 2.9" x 1.7" for desk or rack placement.

Cables and Quad-View expansion included

The package supplies two Dual-Link DVI-D KVM cables and two additional Dual-Link DVI-D cables so both video channels are ready immediately. Linking a second GCS1642 enables Quad View (DCC Mode) across four monitors. An installation guide and warranty card complete the bundle.

Questions about this item

Does the 2560 x 1600 resolution hold steady during long sessions?

The switch is rated for 2560 x 1600 and draws 5.3 V at 2.4 A from the included adapter, so the signal stays stable as long as the power supply is connected.

How much heat or fan noise appears after hours of use?

The unit has no fan and relies on passive cooling; the metal chassis runs warm but stays within normal operating temperature during continuous use.

Which cables and power supply must I already have on my desk?

You need two Dual-Link DVI cables for the monitors, two USB Type-B cables for the computers, and the supplied 5.3 V 2.4 A power adapter.
