Triple-Monitor KVM for Four Computers
This KVM switch lets four desktops or laptops share one keyboard, one mouse and three monitors using two HDMI and one DisplayPort output. It targets multi-system workstations, streaming rigs or lab benches where operators need instant access to several machines from a single console.
Passive Power and Rear-Facing Ports
The unit draws power from the connected computers so no external supply is required for basic operation, though a power adapter is included for demanding USB loads. All video, USB and audio sockets face the rear, keeping cables tidy and the desktop clear. Front-panel push buttons and a wired remote provide two hardware switching methods with LED status indication.
Verify Graphics Outputs and Cable Standards
Each source computer must provide two HDMI and one DisplayPort video output to fill the three monitor inputs. To reach 8K at 60 Hz or 4K at 144 Hz the graphics card, monitor and cable must all support HDMI 2.1 or DisplayPort 1.4 respectively. Systems with fewer video outputs or older cable standards will be limited to lower resolutions.
