What is a KVM Switch?
Welcome back, tech enthusiasts. Today we’re hitting switches. Not lowrider hydraulics, but KVM switches for controlling multiple computers from a single keyboard, monitor and mouse setup. Yes, a KVM switch is short for keyboard, video, and mouse switch, with video referring to your monitor. A KVM switch is a nifty bit of kit that revolutionizes how you control multiple computers.
If this sounds like an appealing tool for your multi-computer environment, read on to discover all you need to know about KVM switches, including what they’re used for, how they work, and whether you actually need one. Once we’ve covered KVM switch basics, we’ll share three of the best KVM switches with you, and even touch upon KVM monitors.
KVM (keyboard, video, mouse) switches
First, let’s answer the burning question: what is a KVM switch? As we mentioned above, a KVM switch is a device that allows you to control two or more PCs without needing the kerfuffle of corresponding keyboards, monitors and mice for each computer. By tapping a hotkey on the keyboard, a button on the KVM switch, or an on-screen-display (OSD) program, the user can quickly switch between different computers or servers, and continue using the same keyboard, monitor and mouse setup with no added hassle.
What is a KVM switch used for?
Increased efficiency, improved management as well as cost and space saving are a few of the benefits that a KVM switch delivers. Most KVM switches feature between 2 and 64 ports, allowing desktop users and server rooms to select a switch that meets their requirements. The ability to effortlessly switch between multiple PCs is useful in many fields. Common applications of KVM switches include the diverse fields of: IT professionals, system admin, video editing, control centers, and financial trading desks.
How does a KVM switch work?
While there are remote and IP-based KVM switches, in the good old fashioned local application of a KVM switch, PCs are connected to the KVM switch via USB cable. Keyboard and mouse inputs are similarly connected via USB, while monitor output is connected via HDMI, DisplayPort, VGA, or similar. When the user selects an input PC, the KVM switch routes the signals from the connected keyboard, monitor, and mouse to the chosen PC.
A KVM switch works by using signal emulation technology. This means that the KVM switch sends and receives the correct signals (from the selected PC) and the single keyboard, monitor and mouse, without impact on CPU operations during switching. KVM switches also offer stable video resolution, support multiple PC platforms and OS, and interface with all keyboard, monitor and mice models.
Do I need a KVM switch?
If you’re regularly using two or more desktop PCs simultaneously, then a KVM switch is really a no-brainer. Bypass the confusion and stress of running multiple keyboards, monitors and mice, and opt for KVM. While KVM switches may not be on every home office worker’s Christmas Wishlist, if you’re controlling multiple systems as developer, system administrator, or other IT professional, then a KVM switch is a must.
A KVM switch streamlines your workflow and reduces desk clutter, especially in professions that require multiple monitors, such as finance, video editing and design. For gamers and techies, who may run multiple PCs or consoles, a KVM switch means simple switching and improved space efficiency. Right, now that we’ve got that out of the way, let’s figure out the best KVM switch for you.
