With a ServSwitch™ DVI CATx KVM Dual Extender for PS/2®, you can send your keyboard, mouse, and DVI-D video signals up to 400 feet (121.9 m) over CAT5, CAT5e, or CAT6 cable.
It works with a PS/2 keyboard and mouse, and is built for today's computers with dual video heads. Connect up to two DVI-D monitors directly to the computer on the transmitting end of the link and two DVI-D monitors at the receiving KVM console.
Imagine what you can do with more monitors connected to your computer. Put a different application on each monitor to eliminate tedious switching between applications. Or if you have an application that uses lots of small windows, expand it across both monitors to provide more work space.
