Is it possible to have 2 extended monitors and get the third being a mirror of one of the two extended?
I'm pretty sure it's not possible through the interface but it may be possible through commands or configuration file.
If it's seems weird for you, here is my setup :
- 2 monitors, pretty classic working with dual monitor
- 1 big TV that I use as a projector to show things off to people (on meetings for example)
