The SV431DVIDDU 4 Port Dual DVI USB KVM Switch with Audio allows four PCs, each with dual DVI outputs, to share two monitors, a microphone and set of speakers, a keyboard and mouse as well as two other USB peripherals.

An ideal solution for graphic and CAD/CAM designers, education and financial institutions, the Dual DVI KVM Switch allows you to instantly switch back and forth between PCs at the touch of a button while maintaining professional level video quality on both DVI monitors. An integrated USB hub allows USB 2.0 peripherals (external hard drives, web cams, etc.) to be shared - eliminating duplicate peripheral costs, and the hassle of connecting and disconnecting devices to multiple machines.

Please Note: While both DVI-I (analog mode) and DVI-D (digital only) are supported by the KVM, all source PCs should output the same signal type for proper switching. It is recommended wherever possible to use DVI-D cables across all PC to KVM and KVM to Console connections. Please contact technical support if you require assistance identifying your source.

Backed by a 2-year warranty and free lifetime technical support.

(4 stars) SOLUTION: If the monitors and USB become unbound!

The manual doesn't say so, but there is another key combination to know about. The manual details using the Q and W to bind/unbind the selected audio channel from the selected monitor+USB. However, what they don't tell you is that it's possible to also unbind the USB hub from the monitor channel. When that happens, your kybd and mouse won't move with the monitors, and you'll have to use the Fn in addition to the n command [n=1..4] to get them linked. Well, I found that the Z and X commands will bind and unbind the USB, respectively. This is likely true for all these types of products.
