The Advantages Of Using A DVI KVM Switches

A hardware component that is used to control two or three computers at the same time by using a sole keyboard, monitor and mouse, is known as a kvm switch. KVM means keyboard, video monitor and mouse. The more modern devices lets users use one set of speakers to be connected to many computers making use of USB devices that are shared between the computers.

As seen on many movies, the kvm also allows for one computer to be connected to many monitors. This is commonly used in public places such as shopping malls, but it can be used in homes where two television sets are used to view the same video streaming from one computer. Datacenters also use these where servers are connected to other computers and it allows for the personnel of the datacenter to log into any of the servers.

A button on the kvm is used to switch control from the one computer to any other computer. The signals will pass from the computer and the keyboard, monitor and mouse will then swap the control to one of the other computers. One can even make the switch by making use of keystrokes using the keyboard.

Multimedia keyboards have issues regarding compatibility. Users complain that kvm signals do not always team up with the keyboard and it means the multimedia keys do not have an effect on the computers that are controlled by the switch. At times monitors are not detected as the correct models or they are not detected at all.

Remote switches allow a person to control a computer that is up to three hundred meters away from where the person in control is standing. The USB powered switches enables one to control computer equipment up to five meters in distance.

To control numerous computers over a local area network, one can make use of kvm over IP switches. This can also be used over telephone lines and it uses IP protocols. The person will use a web browser to do the necessary functions. Data encryption is applied in the case of kvm over IP devices being used on local area networks.

Making use of kvm switches saves time, money, office space, power and expensive equipment. They save a lot of sweat in datacenters as personnel are able to control several servers all at once. Controlling all the computers and servers at once either locally or remotely is now also a possibility.

What are DVI KVM Switches?

DVI stands for Digital Video Interface. It is a video interface standard that allows you stream uncompressed video to monitors or projectors (usually LCD or Plasma). There are two types of DVI; DVI-I and DVI-D. DVI-I stands for DVI-Integrated. That means that it can be used in both digital and analog devices. In DVI-D setups, the "D" stands for Digital. This means that it can only transmit or receive a digital signal.

DVI KVM Switches, or KVMs, allow you to switch through and control multiple computers using one keyboard, monitor, and mouse. You can also use a KVM to control one computer through multiple monitors, mice, and keyboards.

So a DVI KVM is a device that allows the control of multiple devices through 1 keyboard, monitor, and mouse (or vice versa), that's video is streamed using DVI standards and ports. Because of this you can still use you KVM to switch seamlessly between devices, but not have to sacrifice resolution and image quality. Make sure you check out our wide array of DVI KVMs, and feel free to continue browsing the FAQs if you still have unanswered questions.
