EKL-81UA KVM switch has 8 inputs and offers 4 major inputs: monitor, mouse, keyboard, sound. The best you can get with other more expensive brands is 4 inches with a big 4. The main disadvantage is that this switch cannot give the user control in two cases: 1. BIOS boot menu 2. Grub interface (November- Fix) 2020 : It works with grub interface for ubuntu not my centos). These are major disadvantages for anyone who needs to switch to BIOS mode or has multiple operating systems with a grub interface. At the time of this writing, the keyboard does not work if the USB flash drive is in the computer while the computer is booting up.
