Tripp Lite 4-Port KVM Switch by Tripp Lite

Connects 4 HDMI-Enabled Devices to a Single HDMI Monitor, Keyboard and Mouse
This KVM switch lets you access, control, boot and reboot four computers with HDMI ports and switch between them. In addition to desktop and notebook computers, the switch also connects up to four media centers, video game systems, Blu-ray and DVD players, cable and satellite boxes, DVRs and other HDMI-enabled devices. All computers share one HDMI monitor, USB keyboard and USB mouse, which saves space on your desk or workspace.

Switching Between Computers Is Fast and Easy
Use the front-panel push buttons, hotkey commands, mouse movement or the included IR remote control for quick and easy toggling between computers. You can also use the Auto Scan feature to scan all connected computers in five-second intervals automatically. LEDs indicate which computer is currently selected. Please note: Mouse Traversal is a permanent feature and cannot be disabled

USB Hub Lets You Share Peripherals Between Computers
Two USB 3.0 hub ports allow you to share USB peripherals, such as printers, hard drives, scanners, webcams and flash drives, between all connected computers. The hub is backward compatible with USB 1.1 devices.
