Three-monitor KVM for dual-computer setups

The ESTONE SW231-3HD lets two desktops or laptops share three HDMI displays and a single keyboard-and-mouse pair. It presents each system with three video outputs and four USB 3.0 ports, so both machines can drive extended or mirrored desktops without extra peripherals. The unit is new and includes all required cables, a wired remote, and a 12 V power adapter. It suits workstations that need simultaneous multi-monitor access to separate hosts.

Cable routing and port layout

Every HDMI and USB link plugs into the rear of the switch, keeping the desktop free of cable clutter. The front panel carries only the push-button selector and status LEDs, while the wired remote duplicates the switching function for convenient placement. Four downstream USB 3.0 ports accept keyboards, mice, printers, scanners, or other 5 Gbps devices and remain backward compatible with USB 2.0 and 1.1 gear. No internal hubs or additional adapters are required for basic operation.

Sustained 8K60 and 4K120 throughput

Video bandwidth is specified at 8K 60 Hz and 4K 120 Hz over HDMI 2.1 with HDCP 2.3 compliance, so extended sessions at maximum resolution do not drop frames or degrade signal quality. USB 3.0 links maintain 5 Gbps throughput during continuous data transfers, avoiding the 480 Mbps bottleneck of older standards. The metal enclosure and external power supply provide stable operation under full three-monitor, four-peripheral load without thermal throttling or port resets.
