Thank you, Cheyenne.
I have read the posts and made some homework.
I cannot find more threads related to DisplayLink, though Boris recomends to search using this word as a tag, so I will try to research more about DisplayLink.

It seems that this function is enabled in recent updates, but there are many different adapters (USB-VGA video cards), some claim they run with Windows, Mac and Linux (Android?)
and the one recommended here is quite expensive, as it adds 80 bucks to the cost of an EE.

I will go on with the research and tell more later.
Thanks for finding the threads. I didn't think of searching "projector"...
