With the DIGITUS 4-Port KVM Switch for single displays, you can control four 4K-capable PCs using a single USB keyboard and mouse combination. You can easily switch between the four PCs at the push of a button or via a hotkey, eliminating the need to unplug and replug all cables. The output to a monitor is done through the HDMI port on the back. Audio signals from the microphone and speakers are also switched. Additionally, there is a USB port on the front that can be used for other peripherals, such as USB flash drives or external hard drives, on both PCs. The connected peripheral devices are assigned to the active PC. Status LEDs on the front of the switch indicate the current configuration at all times. The switch is completed with a robust metal housing.
