Vszerda 642DH-MST KVM Switch

The Vszerda 642DH-MST is a DisplayPort 1.4 MST KVM switch that lets one user control four computers across two monitors. It suits professionals and power users who need to manage multiple workstations from a single keyboard, mouse and dual-display setup without unplugging cables.

Dual 4K 60Hz DisplayPort MST limits

Multi-stream transport splits a single DP 1.4 input into two video streams, giving dual extended or mirrored displays at up to 4K resolution and 60 Hz per screen. A single monitor can reach 4K at 144 Hz, but only if the graphics card, monitor and cable all support that bandwidth.

Compatibility checks before ordering

Verify each computer provides a DisplayPort 1.4 output or a USB-C port with DisplayPort Alt Mode and an appropriate adapter. Confirm both monitors accept DisplayPort or HDMI input at the desired resolution and refresh rate. Ensure a 5 V power source is available for the switch.

Questions about this item

Which version of this KVM switch should I choose for dual 4K 60Hz monitors?

The 642DH-MST model provides one DisplayPort 1.4 input and dual DisplayPort plus HDMI outputs per computer, supporting two monitors at 4K 60Hz simultaneously from four connected PCs.

What does the 4K 144Hz single-monitor rating mean for my setup?

When only one monitor is active, the switch can pass a 4K 144Hz signal, provided your graphics card, monitor and cable all support that refresh rate.

How does the DisplayPort 1.4 MST interface limit what I can connect?

Multi-Stream Transport splits the single DP 1.4 stream into two independent displays, capping total bandwidth at the DP 1.4 maximum so dual 4K 60Hz works but higher dual-monitor refresh rates would exceed the link.
