Gefen’s 2x1 DVI-DL Switcher ($700) provides a useful method for working on two computers using the same display, keyboard and mouse. Gefen's DVI-2000 HD ($1,400) is a high definition display extension solution that sustains visual clarity at long distances through the use of fiber optics cables. It features a small sender unit connected to the source computer transmits dual link DVI video to a remote receiver unit connected to the display via a multimode fiber optic cable (up to 330ft). It utilizes a power supply that can be connected at either end.


Gefen's Combo Extension Cable provides a simple solution for home offices,
small businesses and personal users who want to centralize their
computers in another room, a closet or across the room. It is equipped with three connectors on each end: DVI for video displays supporting resolutions up to 1920x1200, USB and FireWire. The cable boasts a plug and play installation, requiring the three interfaces at one end to be connected to the computer and to the extended peripherals at the other end. No additional power supply is
needed. The single bundled cable comes in two convenient lengths: 10ft ($100) and 15ft ($130).

Gefen has its upgraded its KVM (keyboard, video, mouse) extender to accommodate
Apple's 20- and 23-inch Cinema Displays as well as Apple's new G5 computers. The CAT5-5000 HD ($1,300) supports the extension of two displays using DVI (digital visual interface) plus a keyboard and mouse using USB using cost-effective, industry standard CAT-5 cables. A small sender unit at the computer is connected to the remote receiver unit at the workstation with four CAT-5 cables, effectively spanning up to 150 feet in distance while sustaining multiple resolutions up to 1920x1200. Both units are rackmountable; the CAT5-5000 HD is fully HDCP (high bandwidth digital content protection) compatible and will support protected digital content at its highest resolutions at extended distances.

The FireWire Repeater 800 comes is offered in a compact, shielded plastic case that connects upstream and downstream FireWire cables; it replicates the data it receives from the source cable and sends it along the second cable to the extended device. The Firewire Repeater 800 is capable of transmitting Firewire IEEE 1394b up to 33 feet and it supports data transfers up to 800Mbps. The USB 2.0 Extender can data at a rate of 400 Mbps over CAT-5 cables, providing a nearly instant transmission at distances up to 150 feet from the computer.
