Four-Port DisplayPort KVMP Switch
The IOGEAR GCS1904 lets operators control four DisplayPort computers from one keyboard, mouse and monitor. It supports video up to 3840 x 2160 at 30 Hz or 2560 x 1600 at 60 Hz. A built-in two-port USB 3.0 hub shares peripherals across all connected systems. The unit is TAA compliant for government procurement.
Replaces four separate console sets
This switch removes the need for four keyboards, four mice and four monitors on a desk. The upgrade is worth it when workspace is limited or when switching between secure and general-purpose machines must be instant. Audio switching handles front and rear 3.5 mm sources without extra cabling.
Install with included cables
The package supplies four DisplayPort cables, four USB 3.0 cables, four audio cables and a 5 V power adapter. Connect each computer to its labelled ports, attach the console, then select systems by pushbutton. Common issues include forgetting to plug the power adapter or leaving a USB 3.0 cable on a 2.0 port, which limits peripheral speed.
