Shared 4K Monitor for Four PCs

The Vszerda KVM switch lets four computers share one HDMI monitor and three USB 2.0 peripherals. A single 3840x2160 display at 30 Hz is driven through the switch, while keyboard, mouse and printer stay connected to the unit. No driver installation is required on Windows, Mac OS, Linux, UNIX or DOS systems.

Two Switching Methods Free Desk Space

Front-panel buttons and the included wired remote let you change the active computer without reaching behind the desk. Four 2-in-1 KVM cables combine HDMI and USB connections, reducing cable count between the switch and each host. The compact unit sits on the desktop and draws power from the attached computers.

Steady 30 Hz Output Under Continuous Use

The HDMI output maintains 3840x2160 resolution at 30 Hz during extended sessions, avoiding the frame drops that can appear in short-burst tests. USB 2.0 peripherals keep consistent connectivity while switching between all four ports. Passive operation means no fan noise or thermal throttling over long work periods.

Does the switch generate noticeable heat or fan noise during continuous daily operation?

The unit has no fan and draws minimal power through the USB 2.0 links, so it runs silently with negligible heat.
