I have run into this in the past, those USB Video cards do not work correctly. Thus, it is a driver issue.

The only way to get Video out of a system that does not have an extra video out is going to be by using the Intel Wireless Display. Some computers have this built in, but some do not, so it really all depends on your system and if it can support that.

I am guessing this is an All In One computer? Most of these only have the single display, and there is not to much you can do about it.
