With the DIGITUS 4-Port KVM Switch for dual displays, you can operate four 4k-compatible PCs using a single USB keyboard and mouse combination. By pressing a button or hot key, you can switch comfortably between all four PCs and are spared the trouble of replugging all cables. Output on up to two monitors is provided via two HDMI® outputs on the rear side. You can also switch between the audio signals for the microphone and speaker. In addition, a USB port is included on the front side for use with other peripheral devices like USB sticks or external hard drives on both PCs. The connected peripheral devices are each assigned to the active PC. Status LEDs on the front side of the switch show you the current configuration at all times. The slim switch features the added benefits of sturdy metal housing.
