Triple-Monitor KVM for Four Computers

The Vszerda DP403B-USB3.0-CZY lets four desktops or laptops share one keyboard, mouse and three DisplayPort monitors. It is built for users who need extended or mirrored layouts across three screens from any of the four connected systems. Each computer must provide three DisplayPort outputs and a USB link to match the switch’s input groups. Buyers whose machines have fewer than three video outputs or who want to share only one or two monitors cannot use this unit as intended.

8K@60Hz via DisplayPort 1.4

The switch passes DisplayPort 1.4 signals up to 8K resolution at 60 Hz, provided every source GPU and every display also support that mode. Lower resolutions and refresh rates are handled automatically. The spec is the single deciding factor: if your graphics cards or monitors top out at 4K, the 8K headroom goes unused, but the switch still works; if any link in the chain lacks DisplayPort 1.4 bandwidth, the 8K@60Hz target cannot be reached.

Manual Button or Wired Remote Switching

A front-panel button and an included wired remote give two ways to change the active computer. The 5 V power adapter must be connected for reliable operation. All cable ports face the rear, keeping the desk tidy, but installation requires matching each computer’s three DisplayPort cables and one USB cable to the correct numbered input group (IN1 through IN4). Cross-connecting any of those twelve video leads plus four USB leads breaks the switching logic, so careful labelling during first setup is essential.
