Thanks, that's good news. I'm actually having trouble finding a way to enable duplicate displays - I get the following options when I open up my control panel and navigate to my display settings:
-Extend these displays
-Show desktop only on 1
-Show desktop only on 2
No desktop duplication available
Please help me, Hobbes! Cheers.
You shouldn't have graphical slowdowns but turning off the monitor makes no difference. Other than unplugging, the gpu still sees a monitor and outputs to it.
