ESTONE SW244-1DP1HD 4K 60Hz 2K 120Hz 4-Port Dual Monitor KVM Switch

Four-computer dual-monitor KVM

The ESTONE SW244-1DP1HD lets a single keyboard, mouse and two displays control four computers. It accepts HDMI and DisplayPort inputs from each system and provides two monitor outputs that can mirror or extend the desktop. Four USB 3.0 ports share peripherals such as printers or external drives across all connected machines.

Upgrade from single-monitor or two-port switches

Replaces setups that require manual cable swapping or a basic two-port KVM. The four-port design is worth it when you regularly work across a desktop, laptop, workstation and test machine and need simultaneous dual-screen visibility. If you only ever use one computer or a single monitor, the extra ports and video outputs add complexity without benefit.

4K 60 Hz and 2K 120 Hz headroom

Handles two 4K displays at 60 Hz or two 2K panels at 120 Hz, with automatic resolution detection when switching sources. USB 3.0 ports deliver up to 5 Gbps for fast storage or peripherals, and the included 12 V power adapter keeps high-draw devices stable. Bandwidth limits appear when driving dual 4K above 60 Hz or when total USB traffic exceeds the shared 5 Gbps upstream link.
