Four-Port Dual-Monitor KVM

The Vszerda DKM402C-USB3.0-NEW lets one keyboard, one mouse and two monitors control four computers. It accepts both DisplayPort and HDMI sources so each system can keep its native video connection. Three USB 3.0 ports share peripherals such as printers, scanners or storage drives across all connected PCs. A 3.5 mm audio output with a built-in DAC and a separate microphone jack complete the workstation consolidation.

Passive Cooling Silent Operation

The unit weighs .87 kilograms and relies on passive convection, so it adds no fan noise to a quiet studio or office. Power draw is limited to the USB 3.0 bus and the external adapter, keeping heat output negligible during extended switching sessions. No active thermal management is required and the metal enclosure dissipates warmth without audible buzz. The switch therefore suits environments where acoustic distractions must stay at zero.

Wired Remote And Multi-OS Support

A desktop wired remote controller provides instant port selection without reaching for the front-panel push buttons. The package includes all necessary DisplayPort and HDMI cables plus USB 3.0 upstream cables for each computer, so the switch works immediately after plug-in. Compatibility spans Windows, Mac, Linux and Unix with no driver installation, and the USB 3.0 hub remains backward compatible with 2.0 and 1.1 devices.

Questions about this item

How do I connect four computers to the two DisplayPort and HDMI monitors without losing 4K 60Hz?

Connect each computer's video outputs to the switch inputs using certified DP or HDMI cables, then link the two monitor outputs; the front push button or wired remote selects the active PC.

Which parts wear out first and need replacement?

The mechanical push button and the 3.5 mm audio jacks see the most physical cycles; cables and USB ports may also degrade with frequent insertion.

What limits sustained 4K 60Hz operation?

Bandwidth is capped at the 5 Gbps USB 3.0 rate and the HDCP 1.4 / HDR 2.2 link; if any cable or GPU cannot maintain the full 3840×2160 60 Hz signal the switch drops to a lower mode.
