Four-PC Triple-Monitor KVM

This KVM switch connects four computers to three monitors using two HDMI and one DisplayPort output per system. It suits professionals who run multi-display workstations and need to share a single keyboard, mouse and USB peripherals across several hosts. The unit includes a wired remote for convenient switching without reaching the main box.

Resolution And Refresh Limits

Video bandwidth supports up to 8K at 60 Hz or 4K at 144 Hz when every link in the chain — cables, monitors and graphics outputs — meets the same specification. HDMI and DisplayPort inputs on each computer port accept both standards, but the highest modes require certified 8K cables. Audio and microphone signals follow the active video channel.

Build And Daily Use

A 12 V DC power adapter is supplied for stable operation across all four USB 3.0 peripheral ports. Front-panel push buttons and the wired remote both change the active computer, while LED indicators show the current selection. Copy and extend display modes let the primary screen mirror or span to the second output, useful for presentations or expanded workflows.

Questions about this item

Should I pick the 2 HDMI + DisplayPort version or a different port mix for my three monitors?

This model provides exactly two HDMI and one DisplayPort output for each of the three monitors, matching a setup with two HDMI screens and one DisplayPort screen.

What does the 8K@60Hz rating mean when I connect my PC and monitors?

It means the switch can pass an 8K signal at 60 Hz provided your computer, monitors and cables all support 8K@60Hz; otherwise it will fall back to the highest common mode such as 4K@144Hz.

How does the USB 3.0 hub limit the speed of my keyboard, mouse and other peripherals?

The four USB 3.0 ports share a single 5 Gbps upstream link, so combined peripheral traffic cannot exceed USB 3.0 bandwidth.
