A KVM switch (Keyboard-Video-Mouse) is a major boon to anyone who has to work with more than one computer. You can change computers without having to give up the keyboard and monitor you're already using, sometimes via the keyboard itself. Imagine the space and money you'll save, only having to buy one monitor, keyboard, and mouse. After saying that, KVM switches stop being exciting pretty quickly, so let's look at things to shop for. Will it switch your speakers, too? How about your microphone? Is it USB only, or can it handle older connections? Hardware button, keyboard command control, or both? Does it draw its power from the computer, or does it need a power adapter? How many computers do you need to switch? (Most KVM switches will handle two computers; some can handle more.) The LINKSKEY LDV-DM712AUSK KVM switch is specifically designed for sharing two monitors (one DVI and one VGA) and features USB support that lets you control two computers with only one keyboard and mouse and dual monitors. 7.1 Type: D-Sub, DVI, USB Computer Connections: 2 Ports Monitor Connections: 2 Ports Video Resolution: Digital Display Resolution: Up to 1920 x 1200 Analog Display Resolution: Up to 2048 x 1536 PC Selection: Push Buttons/Hot Keys PC Connectors: 2 x USB Type B 2 x DVI-I Single Link (Digital Only) 2 x HDB15 (Analog Only) 12 x 3.5mm Audio Jack (For 7.1 Surround Sound) Console Connectors: 2 x USB Type A (For Keyboard / Mouse) 2 x USB 2.0 Type A Hub Ports 1 x USB 2.0 Type A Device Port 1 x DVI-I Single Link (Digital Only) 1 x HDB15 (Analog Only) 6 x 3.5mm Audio Jack (For 7.1 Surround Sound) Temperature: 0ºC to 40ºC(32ºF to 104ºF)
