It also has an on-screen display that lets you keep track of what computer you're currently accessing.
If that's still not enough, you can use more than one of these switches together to control up to 512 computers all with a single keyboard, mouse, and monitor. This is an eight-port switch you can use to connect eight different systems to a single mouse, keyboard, and monitor. While a lot of KVM switches are designed to connect just a few systems, this is a great option if you're looking for something much more extensive.
These picks also don't require additional software for their installation. All of these are great options for the latest computers and displays, thanks to either DVI or VGA and USB support although they're not all ideal if say you need an old PS/2 connection for the mouse and keyboard.
We've chosen the following best KVM switches in 2021 because they all provide the best functionality due to support for at least four different computers, though switches with even more ports are available. While this certainly isn't necessary in every computer setup, a KVM switch makes multitasking easier between multiple workstations and using one setup for more than one system. With the press of a button on the switch (or hotkey if you prefer) you can then use one keyboard, mouse, and video display, easily swapping between the computers you have connected. This then connects to the keyboard/mouse ports and video output on multiple computers. The basic design of this type of switch has input for a keyboard and mouse as well as a connection to a single video display. A KVM switch (or keyboard/video/mouse) is a device that lets you easily swap input devices between two or more computer systems.
