So this is a weird one. My primary display is my laptop with the gtx1060. I have a SideTrak as a second wired display, which is a touch screen. Then when I use my smartphone as a third display, everything works well on the phone(including the touch), and visually everything is well. But when I try to use the touch screen on the SideTrak It thinks I'm touching the primary display on the laptop itself, and not the SideTrak. If I disconnect the Spacedesk device, it goes right back to normal.
