Four-Port DVI KVM Switch
The ATEN CS1784A lets one keyboard, mouse and monitor control four computers through dual-link DVI connections. It is built for administrators, developers or multi-system workstations that need reliable switching without software overhead. A built-in two-port USB 2.0 hub handles shared peripherals such as drives or printers. Independent asynchronous switching keeps keyboard, video, mouse and audio paths separate when required.
Dual-Link Resolution Limits
Dual-link DVI supports 2560x1600 at 60 Hz while single-link DVI tops out at 1920x1200 at 60 Hz. The unit operates from 0 to 50 °C with humidity up to 80 % non-condensing. Cables included are DVI-D to DVI-D with USB, so analog VGA sources cannot be connected without an active adapter. Audio switching covers 2.1 channel output for basic multimedia monitoring.
Upgrade From Two-Port Or Analog KVMs
Moving from a two-port switch adds two extra computer paths without extra desk hardware. Replacing an analog VGA KVM gains digital clarity at 2560x1600 and removes signal degradation on long cables. The jump is worth it when four digital sources must share one high-resolution display and USB peripherals. Buyers who need DisplayPort, HDMI or more than four ports will need a different platform.

Questions about this item
How many computers can I connect to this KVM switch?
The CS1784A supports up to four computer connections, letting you control all four from a single keyboard, monitor and mouse.
What resolution will I actually get on a dual-link DVI monitor?
Dual-link DVI delivers 2560x1600 at 60 Hz, while single-link DVI is limited to 1920x1200 at 60 Hz.
Does the built-in USB 2.0 hub share bandwidth with the KVM switching?
The two-port USB 2.0 hub operates independently, so peripheral switching is asynchronous and does not interrupt the KVM session.
