I stand corrected. It does use it, but apparently it doesn’t count against the display limit. I suppose because it is not physically connected? From what I have read, the GPU is used for compressing the image for transmitting.
I’ve looked up some displayport splitters, but they don’t seem to be bi-directional which I believe is required for touch data. Am I correct? Space desk will not work with my touch monitors since it requires an OS. Works fine with my Galaxy 10.1, but that’s too small for most of my pop-outs.
