DVI KVM Switch: One Set of Peripherals Controlling Multiple DVI Computers

A DVI KVM Switch is used to control multiple DVI based computers using a single set of peripheral devices. Available in both PS2 and USB versions, the models have 2, 4, 8 or 16 ports. Easy to install, the devices work on plug and play functionality. A user needs to connect the peripherals to the input port and the computers to the output ports. Once powered on, the device is ready to be used. It does not require any additional software or device drivers for operation. Offering multi platform support, these devices work with DOS, Win3.X, Win95/98/98SE/2000/ME, WinNT, Netware, UNIX, and Linux.


The DVI Switch is hot pluggable so a user can add or remove connected PCs for maintenance without powering down the switch or the computers. Control can be exercised using hot keys or front panel push buttons. More advanced versions also use the RS232 and Infra red remote control. LEDs on the front indicate the status of the connected devices. Equipped with an auto scan mode to monitor the PCs at intervals ranging between 1 to 99 seconds, these units have operating and storage temperatures ranging between 0 to 50 degrees Celsius and -20 to 60 degrees Celsius respectively. While the PS2 versions of the DVI KVM Switch device support Microsoft Intellimouse, Microsoft Intellimouse Explorer, Logitech Net Mouse, the USB models are compliant with USB 1.1 and some with USB 2.0 specifications.

The DDC2B compliance allows digital communication protocols between a computer display and a graphics adapter enabling the display to communicate its supported display modes to the adapter. Fully compliant with DVI specifications, this compact unit offers superior video quality at a resolution of 1600 x 1200 @ 60 Hz. This KVM Switch is certified by UL, CE and RoHS. Introduced to serve multiple purposes, it’s usage ranges from industrial applications to digital signage.

In environments where the computers are required to be placed in secure environments where there is minimum noise interference and security breach, such as in recording and film studios, information kiosks, hospitals and medical institutions, financial institutions and stock exchanges, the DVI KVM switch comes handy.

DVI KVM Switch - A Switching Device Which Enables Control of DVI Based Computer Systems

DVI KVM Switch is a piece of hardware which can be used to control multiple DVI based PCs or servers. Available in 2 and 4 port versions, this unit is perfect for applications that require analog and digital operation. Useful in server rooms, data or command centers, home office studios, medical centers and/or industrial environments where multiple PCs are used, these devices also save from additional investment on KVM equipment.

Equipped with the benefits and features of easy installation along with plug and play functionality, no software or device drivers are required for installation, they are hot pluggable and it gives user the freedom, so that he/she can add or remove devices without powering down the switch or the computer. These switches are available in different versions including PS2 or USB versions. The latter, known as a USB DVI KVM Switch allows the USB peripherals and PCs to be connected to the switch, while the former adapts to PS2 devices. Compliant with the USB 1.1 specifications, these devices support data transfer rates of 1.5/12 Mbps.

Switching between computers is easy and can be done by using the front panel push buttons or hot keys for both PS2 and USB variants. Another common feature to both the devices is the auto scan mode which allows monitoring of the computers at repeated intervals. This KVM Switch offers multi platform support and works with operating systems such as DOS, Win3.X, Win95/98/98SE/2000/ME, WinNT, Netware, Unix, Linux. Other beneficial features of this switcher includes supporting resolutions up to 1600 X 1200 @ 60Hz, and relay of signals at zero pixel loss. These devices also have a LED that indicates the status of connected PCs.

Also compatible with extenders, which would allow these switches to be placed in a secure location and the peripherals at a distance away from them. This enables a noiseless operation in harsh work environments and or provides extra security when needed. Digital inputs such as flat panel displays, data projectors, plasma displays, digital TVs and set-top boxes and analog video inputs like traditional monitors and TVs can be connected to the DVI KVM Switch. A compact sized desktop unit enclosed in a metal casing, it has female PC and console port connectors. Due to all above mentioned features, these devices enable the user to save time, space, money, power along with other valuable resources.

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.
