What display options do I have with Tap?

What is the screen resolution?
Tap’s touch controller has a 1280 x 800 resolution.

Can I use Tap as my main screen, or do I need a separate monitor?
Tap is intended only for use as the touch controller, so a separate screen is required for the full video collaboration experience. 

Can Logitech Room Solutions connect to dual monitors?
Yes. The bundled PC will support dual display.
