Four-Port VGA KVM Switch

The Explus-C KVM switch lets one VGA monitor and three USB 2.0 peripherals control up to four computers or laptops. It targets offices, studios, classrooms and home setups that need to share a keyboard, mouse, printer or scanner across multiple machines without unplugging cables.

Video limited to 1920 x 1440

The VGA interface caps output at 1920 by 1440, so modern high-refresh or 4K displays cannot run at native resolution. USB 2.0 bandwidth also restricts connected storage or high-polling-rate peripherals to legacy speeds, making the unit unsuitable for workflows that demand faster data throughput.

Plug-and-play with desktop controller

No drivers or external power supply are needed; the switch draws power from the attached computers. A wired desktop button and front-panel keys both change the active port, while LEDs show the current selection. The manual warns against illuminated mechanical keyboards because their extra power draw can overload the USB ports.

Questions about this item

Which version of this KVM switch should I choose for four computers?

The single model connects four computers to one monitor and three USB 2.0 peripherals, so no other capacity option exists.

What does the 1920 x 1440 resolution mean on my display?

It supports up to that pixel count on the shared VGA monitor, with DDC auto-identification for correct timing.

How does the USB 2.0 interface limit my connected devices?

The three shared ports run at USB 2.0 speeds, so high-power devices such as illuminated mechanical keyboards may overload the connection.
