I have my Energy Saver->Battery->'Turn display off after:" set to 2 minutes. This setting is exactly how I want power settings to behave when I'm using the computer on my lap. However, when I hook up to Apple TV for a presentation it still shuts off after 2 minutes which disconnects apple TV and disrupts the presentation.
Is there a way to have a different Energy Saver setting when using Apple TV (or other external monitor)? I frequently switch between using Apple TV and not to the point that changing Energy Saver every time is a burden.
