Dual Monitor KVM Switch

One of the more unusual computer peripherals is the KVM switch, which stands for keyboard, video, and mouse switch. Few computer users would have ever used a KVM switch or even seen one for that matter. The dual monitor KVM switch is even more uncommon but that may be about to change. Dual monitor setups are becoming increasingly popular, especially among professionals who work with lots of data. The smallest KVM switches can handle only two computers but the largest ones can handle more than four.

The KVM switch allows one set of computer peripherals to control multiple computers but only one at a time. Switching between the computers is done by either pressing a button on the front panel or by pressing a hotkey on the keyboard. A typical KVM switch is a rectangular metal box, with a button for each computer and a display showing the number of the selected computer. A dual monitor KVM switch is slightly larger than a regular model because it has an extra row of video ports on the back panel.

Most computer users do all their work on just one computer, but there are some professionals who need to use multiple computers every day. System administrators often manage banks of computers, known as server farms. These are used to render 3D animations, simulate computer models, and process large amounts of data. Computer technicians also use multiple computers to run tests on several components at the same time. To avoid installing a set of peripherals for each computer, these professionals use KVM switches to save both money and desk space.

The dual monitor KVM switch is designed especially for computers with two monitors. It only takes a few applications to fill the screen space of the largest monitors. When many applications need to be open at the same time, a lot of time gets wasted cycling through them looking for a particular one. In those situations, it’s much better to have them spaced out across two monitors or even more if need be. Stockbrokers frequently use six or more monitors to watch hundreds of stocks at the same time.

The manufacturers recognize that a lot of older computers and peripherals are still in use today, so you will often find two types of dual monitor KVM switch in the stores. The first type is designed for the latest computers, and features two DVI ports for LCD monitors along with USB ports for a keyboard and mouse. The other type is designed to support a mix of new and old equipment, and has a VGA port for an older monitor along with PS2 ports for an older keyboard and mouse. Of course, you can still use old equipment with the first type by simply placing a port adapter on the end of their cables.

Before choosing a dual monitor KVM switch, check that its maximum resolution is suitable. Some models may not be able to handle the highest resolutions used today. On the front panel, the buttons should be large and clearly labeled, and the status display should be easy to read. The ports on the back panel should be organized into groups and have good separation. The case should have rubber feet and be rugged enough to support books and other objects on top of it. Some models even have audio ports which can be used with surround sound speakers.

Installing a dual monitor KVM switch can take a while due to the large number of plugs that need to be connected, but once they are in there is rarely any need to remove them. The peripheral cables are connected to the console sockets, and the computer cables are connected to the other sockets. Each computer needs to be configured in the video options to use dual monitors, and software may need to be installed on each one to enable hotkeys and other features. A wall socket also needs to be found for the AC adapter used by the KVM switch. Once that is all done, the computers can be switched with just the press of a button.
