ESTONE SW242-2HD KVM Switch 4-in 2-out 4K@60Hz 2K@120Hz

Four-computer dual-monitor KVM

This ESTONE SW242-2HD switch lets four computers share two HDMI displays and a single keyboard-and-mouse set. Each computer must provide two HDMI outputs to feed both monitors. USB 3.0 ports allow shared access to up to four peripherals such as printers or storage devices. The unit ships with cables, a 12 V power adapter, an IR cable, a remote control and a user manual.

Sustained switching behaviour

Push-button or remote selection toggles between the four connected PCs without interrupting the video signal on either monitor. An auto-scan mode cycles inputs every 3 seconds for unattended monitoring. LED indicators show the active computer at a glance. The switch maintains 4K 60 Hz or 2K 120 Hz output continuously during extended sessions.

Build and connectivity implications

The compact enclosure measures 5.43 by 5.35 by 1.46 inches and weighs 9.52 ounces, fitting easily on a crowded desk. Four USB 3.0 type-A ports face the front for quick peripheral swaps. HDMI 2.0b cables are required for full 4K 60 Hz performance. The external power adapter ensures stable operation when all four computers and multiple USB devices are connected.
