Note: A basic 2-port VGA model is available for 20 dollars, whereas a 4K 4-port unit with additional features is available for hundreds of dollars.


  • They are easy and straightforward to use.


  • There must be a physical connection between all the computers and the hardware KVM switch.
  • The cable length required for the entire connection set-up is increased, thereby increasing the budget.
  • KVM switches are a bit slow compared to standard conventional switches. It might take few seconds to switch between systems, which may be inconvenient.

Using Software KVM Switches

It is just a software solution to connect two or more computers with the primary computer’s input devices.

It is a software solution to connect two or more computers with the input devices of the primary computer. These KVM switches cannot directly help you connect two or more computers to a single monitor. However, they can be employed and the hardware KVMs to manage such connections in a compatible manner.

 Here are some examples of these software packages:

  • Synergy (It is available for a one-time purchase)
  • ShareMouse (It is available free for personal use)
  • Input Director (It is available free for personal use)
