As for the first question: I expect most of the time, it is usually stated in the specs.
Never presume anything if it is really important to you ask (the supplier/manufacturer/both) or stay away.
As for the second question: Don't know I guess it would become a lot more complicated as their is no direct input for the screen and you would have to use a usb line or ethernet, software ect. I guess it would be possible with enough effort.
If all else fails: Read The Manual
