mac pc setup using two external monitors I have MacBook Pro late 2013 and PC with Windows 10. Also, I have two Dell U2414H monitors.

My setup looks like this:


MacBook Pro is connected via DisplayPort with both monitors.
PC is connected via HDMI with just one monitor.


Problem is with mac when I want to run OS X and Windows simultaneously. When I switch input source on one monitor to HDMI (for Windows), macbook still "thinks" it's connected to both monitors and renders screen on both and it put some pressure on GPU… I guess it's because monitor is enabled and signal is going through DP cable to mac.

Is there anything I can do? Because right now I have to manualy disable cable every time and it's annoying as I need to do this few times a day.
So it turns out that the only solution is to use mirroring display. The signal is still sent but GPU is not overworking. MacBook doesn't heat up as with regular using two displays.
