A KVM (Keyboard Video Mouse) switch is a must-have device for anyone juggling multiple computers and looking to reduce desktop clutter. By allowing you to control two, four or even eight computers from a single keyboard, mouse and monitor, a KVM switch maximizes efficiency and eliminates the need for duplicate peripherals.
But with so many KVM switch options on the market, how do you determine which model best fits your needs and budget? This definitive guide breaks down the six best KVM switches available today based on performance, features and value. We‘ll compare and contrast the pros and cons of each pick so you can find your ideal match.
How Do KVM Switches Work?
Before diving into the top KVM switch recommendations, let‘s quickly review how these clever devices function.
A KVM switch allows you to connect multiple computers to shared input and output devices. This means several PCs can utilize one keyboard, mouse and monitor.
The switch itself enables you to toggle which computer‘s video feed gets displayed on the monitor. It also channels the keyboard and mouse input to control the active machine.
This allows seamless switching between multiple connected PCs without having to swap cables around. It‘s an efficient and clutter-free way to operate multiple computers from a single workstation.
Most KVM switches handle two to four PCs, but specialty models can accommodate up to 64 machines!
Key Benefits of Using a KVM Switch
Saves Money – Reduces costs by eliminating duplicate peripherals for each computer
Saves Time – Swift switching between PCs improves workflow speed
Saves Desk Space – Consolidates equipment into a compact hardware configuration
Enables Collaboration – Allows coworkers to share access to a PC from one keyboard and screen
Allows Remote Access – Manage networked machines from a central console
Increases Security – Isolates secure networks and controls access between machines

KVM Switch Buying Considerations
Keep the following key criteria in mind when selecting your KVM switch:
Number of Computers
Consider current needs and likely future growth. For home use, a 2 or 4 port KVM is generally sufficient. But power users can utilize switches supporting 8, 16 or even 64 devices.
Video Resolution
Lower-end KVM switches max out at 1920×1080 (1080p) while higher-end models offer 3840×2160 (4K UHD) for the latest Multi-HD and UHD monitors. Bear in mind cables like HDMI 2.0 are required to handle huge resolutions exceeding 1080p.
Peripheral Compatibility
Look for appropriate peripheral ports (USB, Thunderbolt etc.) to match your computer hardware. Also confirm that your KVM supports necessary peripheral data rates, like USB 3.0 for high-speed external storage drives.
Display Support
For multi-screen setups, choose an extended desktop KVM switch specifically supporting dual or even quad monitor configurations.
Console Type
Desktop KVM switches allow operation next to the connected PCs using screen, keyboard and mouse. Rack mountable switches with separate console allow control from a switch hub installed remotely in a data center.
Security Features
For sensitive applications, secure government and military KVM switches prevent data flows between isolated networks via encryption, authentication and physical chassis protections.
By keeping these criteria in mind and matching technical capabilities to your needs, you‘re sure to locate just the right flavor of KVM switch.
