Introduction
Overview
The CS1922 / CS1924 2/4-Port USB 3.0 4K DisplayPort KVMP™ Switch
takes a giant leap forward in KVM switch functionality by combining a KVM
switch with a DisplayPort video interface, 2-port USB hub and 2.1 channel
audio support for rich bass in surround sound. DisplayPort technology provides
a 4K UHD @ 60 Hz and 4K DCI @ 60Hz resolution that displays the most
vivid high-definition images available while pumping out premium sound for
music, movies, and games.
As a KVM switch, the CS1922 / CS1924 allows users to access two or four
DisplayPort computers from a single USB keyboard, USB mouse and monitor
console. In addition to the front panel pushbuttons and hotkeys, the CS1922 /
CS1924 offers the latest mouse port-switching functionality which allows a
double-click of the mouse’s scroll-wheel to change ports. A Power On
Detection feature also ensures that if one computer is powered off, the CS1922
/ CS1924’s will automatically switch ports to the next powered-on computer.
With a built-in USB 3.1 Gen 1 hub, the CS1922 / CS1924 SuperSpeed 5 Gbps
transfer rates to all connected peripherals. The unit’s independent
(asynchronous) switching feature, allows the KVM focus to be on one
computer while the USB peripheral focus is on another computer. This
eliminates the need to purchase a separate USB hub or stand-alone peripheral
sharer – such as a print server, modem splitter, etc.
Featuring an unbeatable combination of ultra high 4K resolutions, a next
generation USB 3.1 Gen 1 hub and enhanced, user-friendly operations, the
CS1922 / CS1924 provides the latest innovations in desktop KVM switching
technology.

3. MST requires two monitors capable of DisplayPort 1.2 daisychaining, or use of a powered DisplayPort MST Hub. The PC
source must be DisplayPort 1.2 compliant. A DisplayPort v1.1a
display can be the last display in a DisplayPort v1.2 chain.
4. Dual-Mode DisplayPort technology (DP++) does not require an
active adapter for most single display setups. Active DisplayPort
adapters are recommended if you are unsure of the video source's
DP++ compatibility.
5. PC keyboard combinations emulate Mac keyboards. Mac
keyboards only work with their own operating system.
