USER MANUAL GCS1934M IOGEAR

IOGEAR's GCS1932M/1934M 2/4-Port 4K DisplayPort KVMP Switch with Dual Video Out and RS-232 takes a giant leap forward in KVM switch functionality by combining KVM switch with a DisplayPort video interface, 2-Port USB 3.1 Gen1 hub and 2.1 channel audio for rich bass in surround sound. DisplayPort technology provides up to 4K DCI - 4096 x 2160 @60Hz resolution that displays the most vivid high definition images available while delivering premium sound for music, movies, and gaming.

GCS1932M/1934M allows users to access two or four DisplayPort computers from a single USB keyboard, USB mouse, HDMI and/or DisplayPort monitor(s). In addition to the front panel pushbuttons, hotkeys, and RS-232 commands, IOGEAR's GCS1932M/1934M offers the latest mouse port-switching functionality to change ports. Power ON detection feature also ensures that if one computer is powered OFF, the GCS1932M/1934M will automatically switch port to the next powered ON computer.

With built-in USB 3.1 Gen1 hub, each connected computer has SuperSpeed 5Gbps transfer rate to all connected peripherals. GCS1932M/1934M's independent (asynchronous) switching feature allows the KVM to focus on one computer while the USB peripheral focus on another. This eliminates the need to purchase separate USB hub or stand-alone peripheral sharing device – such as printer server, modem splitter, etc.

IOGEAR's GCS1932M/1934M's built-in MST hub receives DisplayPort 1.2 signals from the source device, independently splits and routes the video signals to multiple monitors.

Featuring a revolutionary combination of 4K resolutions, the next generation USB 3.0 Hub, and enhanced user-friendly operation, IOGEAR's GCS1932M/1934M provides the latest innovations in desktop KVM technology.

Troubleshooting

Operation problems occur due to variety of causes. The first step in solving them is to make sure that all cables are securely attached and plugged in completely in their sockets.

In addition, updating the GCS1932M/1934M's firmware may solve problems that have been discovered and resolved since the prior version was released. If your product is not running the latest firmware version, we strongly recommend that you upgrade. See The Firmware Upgrade Utility for upgrade details.
