This should be fixed in M64. When the system is unable to detect which display to associate the touch device with, it will default to the internal display. It will have to be reassociated manually to the correct display. You will have to enable enable-touch-calibration-setting in chrome://flags

What version are you using? The setting will allow you to connect all touch devices only in version M64 and above.
