4-Port HDMI KVM for multi-PC control

The Teamyo KVM switch lets one keyboard, mouse and monitor command four computers through four HDMI and USB-B groups. It is built for users who need to move between separate desktops, workstations or consoles without duplicating peripherals. The device draws power from a single USB cable so no external adapter is required.

Passive cooling and USB-powered operation

With no fan or active cooling the unit runs silently on a desk or in a rack. Power comes from the included USB charging cable, keeping the total draw low enough for a standard USB 2.0 port. The compact enclosure stays cool during typical switching sessions and adds no audible noise to the workspace.

Bundled cables and remote simplify setup

Four USB-B male cables connect each host directly, while a wired desktop controller provides push-button switching away from the main box. A printed manual walks through the required HDMI-plus-USB-B pairing for every port. Note that HDMI cables are not included and must be sourced separately.

Questions about this item

How do I install the KVM switch and which step do people often miss?

Connect each computer with both an HDMI cable and a USB-B cable, then plug the keyboard and mouse into the dedicated USB 2.0 ports on the front. The step most often missed is forgetting the USB-B cable on one or more ports, which prevents switching for those computers.

What maintenance or replacement will this KVM switch need later?

No scheduled maintenance is required. If a USB 2.0 cable or the remote switching button fails, replace that cable or the remote unit. The switch itself has no user-serviceable parts or consumable components.

What limit appears first during sustained 4K 30Hz use?

The video output is capped at 3840x2160 at 30Hz, so that refresh rate is the hard ceiling for 4K content. USB peripherals are limited to USB 2.0 bandwidth, which can become the bottleneck for high-speed devices during long sessions.
