I use a Dell all in one as a second screen for my laptop. Now, the All in one has got a regular second screen. This is connected to the all in one via Displayport.

Is it now possible to use the second screen of the all in one as the third, when the all in one with HDMI is connected to the laptop?

No, this is not possible.

I'm not 100% sure, but 99% think NO.
