I have a late 2013 rMBP and I have a question. I currently have it hooked up to an external monitor via thunderbolt to VGA. I also have an Xbox One attached to the monitor via HDMI. When I switch inputs from VGA to HDMI on my monitor, my mac does not recognize this and continues to act as if the external monitor is active. The only way around this that I have found is to unplug the thunderbolt connection into my laptop, which will force the mac into single display mode. Is there a way to achieve this without unplugging it each time?
