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 denition 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.
