Laptop Display to Two Additional Monitors

[skarlorn]

Is this possible? I've sent connection from a laptop to two external monitors using the HDMI and VGA ports, but I've never been able to isolate the display to the external monitors.

Is there a way to finagle it so that the laptop's own display is the tertiary screen, or disable it altogether while the monitors are plugged in?

Currently on Windows 8.1 somehow.

Also interested if possible for Mac.
