Four-computer triple-monitor KVM

This KVM switch lets four computers share three high-resolution monitors and four USB 3.0 peripherals such as keyboards, mice, printers or game controllers. Each connected PC must provide one HDMI 2.1 and two DisplayPort 1.4 outputs for full operation. The unit includes push-button selection, LED indicators and a wired remote for convenient switching.

Passive cooling with external 12 V supply

The device draws power from an included DC 12 V adapter and has no internal fans, so it operates silently in normal use. USB 3.0 ports deliver up to 5 Gbps data transfer, well above the 480 Mbps limit of USB 2.0, without adding audible noise or noticeable heat.

Stable video under continuous multi-session load

Extended and Mirror modes are maintained across all three displays during long work or gaming sessions without signal drop or resolution scaling. Backward compatibility with 4K@60 Hz, 1080P and 720P ensures consistent output when source devices negotiate lower refresh rates.

Questions about this item

How do I connect my four computers so each one drives all three monitors through the DP 1.4 and HDMI 2.1 ports?

Each computer needs one HDMI and two DisplayPort outputs. Connect the three video cables from each PC to the corresponding KVM ports, plug the three monitors into the switch outputs, attach the four USB cables between the PCs and the KVM, then power the unit with the included 12 V adapter.

Which components will need replacement first if I run three 4K@144 Hz displays continuously?

The 12 V power adapter and the four USB 3.0 cables are the only field-replaceable parts; the switch itself has no user-serviceable fans or batteries, so plan to swap the adapter or cables if they show wear.

What thermal or bandwidth limit appears first when all four computers push 8K@60 Hz through the switch for hours?

The DP 1.4 and HDMI 2.1 interfaces cap video at 8K@60 Hz and 4K@144 Hz, while USB 3.0 peripherals are limited to 5 Gbps; sustained loads stay within those fixed bandwidth ceilings.
