IOGEAR’s GCS1902/1904 2/4-Port DisplayPort KVMP with USB 3.0 Hub and Audio takes a
giant leap forward in KVM switch functionality by combining KVM switch with a DisplayPort
video interface, and 2-Port USB 3.0 hub. DisplayPort technology provides up to 4K UHD -
3840 x 2160 @30Hz resolution that displays the most vivid high denition images available
while delivering premium sound for music, movies, and gaming.
GCS1902/1904 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 GCS1902/1904 offers the latest mouse port-switching
functionality to change ports. Power ON detection feature also ensures that if one computer
is powered OFF, the GCS1902/1904 will automatically switch port to the next powered
ON computer.
With built-in USB 3.0 hub, each connected computer has SuperSpeed 5Gbps transfer
rate to all connected peripherals. GCS1902/1904’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 GCS1902/1904 provides the latest
innovations in desktop KVM technology.
