Does the Pearl Mini stream/record the pc's screen (screen capture)?

I need to know before buy one.

Pearl Mini is a standalone recording/streaming and live switching device. You can certainly capture the HDMI out of a computer connected to an input on Pearl Mini, however it is important to note that Pearl mini does not interface directly with software on a PC.

Is there somewhere to show how this is done??

Can you please be more specific as to your question:

capturing the output of a computer to Pearl Mini?
