Dual-monitor 4-PC KVM
This HDMI KVM switch lets four computers share one keyboard, one mouse and two monitors. It supports extended or mirrored desktop layouts at up to 3840 x 2160 resolution at 30 Hz. Windows, Mac, Chrome OS and Linux systems are all compatible. The unit includes an integrated USB 3.0 hub for sharing peripherals such as printers or scanners.
Sustained switching behaviour
Seamless switching changes the active computer without a blank screen or noticeable delay. EDID emulators on every input keep display settings stable during continuous hot-plug events. The USB 3.0 hub maintains 5 Gbps throughput during long file transfers across all four ports. RS-232 and remote-control commands execute reliably during extended unattended sessions.
Thermals, noise and power
The switch draws power from the included adapter and requires no separate supply. Passive cooling keeps the metal enclosure warm but silent during normal operation. No fans or moving parts generate audible noise. Power consumption stays low while driving dual 4K outputs and the USB 3.0 hub simultaneously.

Questions about this item
Does the WRIARICH KVM switch generate noticeable heat or fan noise when left running all day with four computers?
The unit requires no additional power supply and has no fan, so it runs silently and produces minimal heat during continuous operation.
What cables and peripherals must I already own to connect four computers and two monitors to this switch?
You need two HDMI monitors, one keyboard, one mouse, and the switch includes 1.8 m HDMI and KVM cables for each of the four computers.
Will my older 1080p monitors work correctly with the 4K@30 Hz HDMI 1.4 outputs on this KVM?
Yes, the video resolution is downward compatible, and built-in EDID emulators on each input keep older 1080p displays recognised when switching between computers.
