Three-Monitor KVM for Two Computers
This KVM switch lets two PCs or laptops share three displays and four USB 3.0 peripherals from one keyboard and mouse. It accepts two HDMI 2.1 inputs and one DisplayPort 1.4 input per system, then routes them to matching monitor outputs. The unit operates without an extra power supply, drawing what it needs from the connected hosts. A wired remote and front push buttons both change the active computer.
Bundled Cables and Remote Simplify Setup
The package includes two HDMI cables, three USB 3.0 cables, a 1.5-metre wired controller and a 12 V DC adapter alongside the manual. These items let you connect both computers and all three monitors immediately, while the remote keeps the switch itself out of sight on the desk. The adapter is optional — the switch will run from host power alone — but it is supplied for installations where USB bus power is limited.
Resolution Headroom and Switching Limits
HDMI outputs reach 8K at 60 Hz or 4K at 120 Hz, while the DisplayPort output reaches 8K at 30 Hz or 4K at 144 Hz, all with backward compatibility. Extended mode drives three independent desktops; duplicate mode mirrors the same image across every screen. The switch only supports two computers, so a third host cannot be added, and each video path is fixed one-to-one — input A always maps to output A.

Questions about this item
Will the DC12V power adapter need replacing after extended use?
The unit ships with a DC12V power adapter; it draws no power from the USB ports, so the adapter is the only part that may age and require replacement.
Which port caps the sustained 8K refresh rate first?
The DisplayPort 1.4 output is limited to 8K at 30 Hz, while both HDMI 2.1 outputs sustain 8K at 60 Hz, so the DisplayPort path hits its ceiling first.
Does the switch generate noticeable heat or fan noise during all‑day operation?
No fan is fitted and the specs list no active cooling; the device runs passively, so heat and noise stay minimal even with three monitors active continuously.
