ESTONE SW240-HD 4K KVM Switch

The ESTONE SW240-HD is a 4-port HDMI KVM switch that lets four computers or laptops share one monitor and four USB 3.0 peripherals. It supports video resolutions up to 4K at 60Hz and 2K at 120Hz for mirrored display output. The unit works with Windows 11, 10, 8, 7, Vista, XP, 2000, Linux, UNIX, Ubuntu and Fedora without requiring driver installation. It is designed for users who need to control multiple systems from a single keyboard, mouse and display setup.

Installation and common issues

The switch is plug-and-play with no software drivers needed for any supported operating system. All HDMI and USB ports are located on the rear panel to keep cables tidy and reduce desktop clutter. Switching between computers is done via the front push buttons or the included IR remote control. The package supplies four USB 3.0 A-to-A cables and a 12V 1A external power adapter. Buyers who need to connect more than four computers or who require dual-monitor output will need a different solution.

Sustained-load behaviour

The HDMI 2.0 interface maintains stable 4K 60Hz video during extended sessions without signal degradation. USB 3.0 ports deliver up to 5Gbps bandwidth for attached peripherals such as printers, scanners and input devices. Auto-scan mode cycles through connected computers at a fixed 3-second interval for unattended monitoring. LED indicators show the active port continuously so status is clear during long-running operations. The external power supply ensures consistent performance when all four USB ports are in use simultaneously.
