DVI Mixer
by toby harris. “A controller with DJ style crossfader, ‘Fade to Black’ knob, and video format selector (see below).
A video processor with two DVI-I inputs and a single DVI-I output, capable of the video formats following. The output is locked to its own timebase, ensuring solid output regardless of inputs. The input’s EDID switches to the current video format so your laptop should automatically change to the current resolution.”
