    Hello. I would like to connect my Macbook to external display and use it in mirrored mode. Is there an app to turn off the MacBook screen without closing the lid? I just want to see the external display.

    You could press the F1 key to turn down the display backlight brightness and even shut it off.

    Also know, that the display with the lowest resolution determines the maximum resolution used on both, thus one display will have a lower than native resolution, except when both displays have the same native resolution.
