Rispondi a: Why is my display not fully waking from sleep?OK, so I have a very similar problem, in that my Macbook Pro won't wake up the external screen properly. I can see & move the mouse pointer, but only the internal screen will work. In addition, the external screen is my primary monitor, and if the Mac has locked the screen while I'm away, the login is invisible on the external monitor. So: I use an app called MacID to lock and unlock the computer using my iPhone, and it also allows me to unlock the MBP with a tap pattern on the touchpad. The second thing is that I've got the bottom right hand hot corner set to turn off the screen. So, after logging in, I move the mouse to the bottom right corner, which turns off both screens, then move it back to the centre of the screen, which causes BOTH screens to wake up correctly. I was looking for a proper fix when I found your post, so maybe this might help you work around the problem.
