Not such a simple case as need to switch in and out of DV InfoFrame and have the other HDMI setting inline like 8bit / 12bit and RGB / YUV
Plus would it work in all combos ok.
Not something I am looking to do, but if someone wants to have a go can start by reading up on the commands in the original thread for VS10, that semi worked in switching things on the fly.
Oh and it probably also depends on how the Display switches some maybe better/more tollerant than others.
