The Gefen ex"TEND"it EXT-DVIKVM-241DL is a 2x1 DVI KVM DL Switcher which allows you to easily switch between two cross-platform dual link DVI computers using just one dual link DVI display and USB 2.0 keyboard and mouse. Dual link DVI describes the use of all 24 pins of the DVI connector to achieve mega high video resolutions up to 3840x2400. USB 2.0 is the next generation of USB capable of sending data significantly quicker than before. Stereo audio is routed through along with the video to the display. Audio, video and control signals are "switched" for each computer upon selection, providing you with an easy and effective method of accessing two computers from one workstation without the hassle of networking.

How this DVI KVM switch works:

Connect your dual link DVI display and USB 2.0 keyboard/mouse to the Switcher's outputs. Then you connect both computers' dual link DVI, USB and audio ports to the Switcher's inputs using the supplied cables. From there, you select the computer you want using the IR remote that comes with the unit or with any contact closure remote control. You can choose between a Macintosh or PC keyboard/video/mouse combination.

Question: does this DVI KVM support wireless device standards (i.e., mouse/keyboard)? I'd like to plug in my mouse receiver and keyboard receiver to the KVM outputs
Answer: Thank you for your inquiry. Unfortunately, due to the very different way in which wireless keyboards and mice communicate, support is pretty hit or miss for any particular environment. The best chance for success is a high quality device (like this one), that has transparent USB pass-through, without any kind of keyboard emulation.

From reading the support material, it does not appear there will be any emulation issues with this device. Further, the manufacturer, while not explicitly stating support for wireless devices, let us know they are not seeing any issues with wireless keyboards and mice. From the available information, it looks like this switch will have an excellent chance of working with your wireless devices.

However, please note, we could not guarantee it would work in any particular environment.
