What is a KVM Switch and Does it Work?
Contents
KVM stands for “keyboard, video, mouse” and a KVM switch is a device that allows you to control two or more computers with the use of just one mouse, keyboard, and monitor. These devices are commonly used in places where a person needs to be able to easily access large amounts of data that necessitate the use of two or more computers.
Also known as PC switches, server switches, and CPU switches, these units are small in size and can accommodate anywhere between two and eight different computers at the same time. If you want to use several computers simultaneously, a KVM switch is the answer.
What Are the Benefits of a KVM Switch?
Probably the most important benefit of purchasing a KVM switch is that you’ll be able to access two or more computers with the use of just one keyboard, monitor, and mouse. This will allow you to sit comfortably in one place so that you can focus on what you’re doing, and not on which computer accessory you should be using.
A KVM switch will also save you money as you will not have to purchase additional keyboards, monitors, and mouses. Fewer computer accessories equals less clutter, allowing you to keep your desk area clean and organized.
How to Set Up a KVM Switch
Setting up a KVM switch is easy. Usually, the most difficult aspect is simply ensuring you have all the proper gear. You’ll need two sets of cables for two computers, three for three and so on. You’ll want a good computer desk for all the components too.
Before you start, turn off both computers. Then hook up the all relevant devices to the corresponding input ports on the KVM switch. Monitors, keyboards, and mice are the most common devices used with KVM. But many other standard devices can also be connected, such as a drawing table or speakers.
Once all devices are connected, you can turn on both computers. Every connected computer should automatically identify the switch. Switch between each computer to ensure every device works properly. Many people label each computer port to limit confusion.
