The Gefen EXT-DVI-841DL is a 8x1 DVI SL/DL Switcher which routes one of eight single link or dual link DVI sources to one single link or dual link display.

The rackmountable Gefen 8x1 single link/dual link DVI Switcher offers an economical solution by eliminating the need to purchase many displays for each computer in a studio or lab environment. A plug-and-play solution, the 8x1 DVI-SL/DL Switcher shares one display with up to eight computers. The source computer is selected using the included IR remote control or through RS-232 control.

The DVI monitor is connected to the switcher's output. Up to eight DVI-SL/DL sources connect to the switcher's DVI inputs using the included DVI cables. The included 5V DC power supply is plugged into a power outlet and connected to the switcher. The currently selected DVI source appears on the shared monitor. Sources are selected/switched using the included IR remote control, the RS-232 control, or the input selector push button on the front panel.

Question: Does this work well with OS X?
