Video ports on TxC panels

[fsturlese]

Hello, the TxC panels brochure shows two video connectors on the back of the unit, one DVI and one VGA.
Do they output the video signal to an external monitor, or do they get an external video signal and show in the built-in display? In other words, are they inputs or outputs?
Thanks,
Federico.

The TxC is a PC touch screen. The ports are output ports like you find on a normal desktop PC.
