IOGEAR’s GCS1932/1934 2/4-Port DisplayPort KVMP with USB 3.1 Gen1 Hub and Audio
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 - 4096 x 2160 @60Hz
resolution that displays the most vivid high denition images available while delivering
premium sound for music, movies, and gaming.
GCS1932/1934 allows users to access two or four DisplayPort computers from a single
USB keyboard, USB mouse, and DisplayPort monitor console. In addition to the front panel
pushbuttons and hotkeys, IOGEAR’s GCS1932/1934 o󰀨ers the latest mouse port-switching
functionality to change ports. Power ON detection feature also ensures that if one computer
is powered OFF, the GCS1932/1934 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. GCS1932/1934’s independent (asynchronous)
switching feature allows it to focus on one computer with the USB peripheral focus on
another computer. This eliminates the need to purchase separate USB hub or stand-alone
peripheral sharing device – such as printer server, modem splitter, etc.
Featuring a revolutionary combination of 4K resolutions, the next generation USB 3.0
Hub, and enhanced user-friendly operation, IOGEAR’s GCS1932/1934 provides the latest
innovations in desktop KVM technology.
