Device to split DVS signal

[Galvan77]

Hi I'm looking for a method or device that splits incoming DVI signal (one to passthrough and go directly to the new Microsoft Perceptive pixel and one to split off to a recording device). Ideally this device literally just passes through the signals, doesn't need to do any conversions. Any ideas if such a thing is available?

Note: Typo in the title; should say DVI
