Touch screen when using Dell OptiPlex 7400 as external monitor

Hi everyone, I have a question about my AIO Dell 7400
Can I still use the touch screen on 7400 when it is using as external monitor? Can it happen? Thanks

Afraid to say that you can not use the touch screen when it is being external display mode.  The touch screen connector, the driver and the control app are resided in the AIO.  The external device does not "see" the touch function and could not communicate with it.
