Four-port VGA KVM with USB 2.0

The YINGHUA switch lets one keyboard, mouse and monitor control four computers or laptops. It draws power from the attached USB cables so no external adapter is required. A single push-button toggles the active system instantly. The box includes four 1.5 m VGA-USB cables for immediate setup.

1920 x 1440 video headroom

Maximum supported resolution is 1920 x 1440, which covers legacy business displays and older LCD panels. USB 2.0 peripheral ports accept printers, scanners, flash drives or cameras alongside the keyboard and mouse. Higher-resolution monitors or USB 3.0 devices will not operate at their native speed or clarity.

Passive cooling and silent operation

The ABS plastic enclosure has no fan and dissipates heat passively during normal use. Power consumption is limited to the USB bus supply from the connected computers. Operation is completely silent, making the unit suitable for quiet offices, classrooms or home workspaces.

Questions about this item

Will the 1.5 m VGA cables reach my older tower if it sits on the floor?

Each of the four included cables is 1.5 m long, so a floor-standing tower up to about 1.5 m from the switch can be connected without extensions.

How do I confirm the switch is passing 1920 x 1440 to my monitor?

Set the attached computers to 1920 x 1440; if the monitor displays that resolution without flicker, the KVM is passing the signal correctly.

Does the box include a separate power adapter or must I buy one?

No external power adapter is included or required; the unit draws power from the connected computers via the USB cables.
