Windows 10: Accidentally turned of display, black screen/no mouse

While using PowerPlanner7, I believe I may have accidentally turned off display or brightness to 0. I am unsure if I successfully made it back to the desktop after rebooting(my attempt to solve the problem). I have tried searching the Internet for shortcuts that re-enable screen or turn brightness up(my keyboard brightness buttons do not work since I am on Mac and the functions keys are all remapped- holding fn then function is same as just pressing function now too)

If you guys hide the proximity sensor, the display will go black... It has been provided to save power so that the screen doesn't stay turned on when talking over your phone keeping it close to your ears. So if you accidentally cover the proximity sensor,
your display is going to sleep...

 

Black screen: Windows 10

I had a similar problem after Windows updates. The reason seems to be the display driver for NVIDIA GeForce GTX 770. My screen turned black after restart, but I had the mouse cursor.

I noticed that I could move the mouse out to the left. When I moved the mouse out of screen in other directions it came back instantly, but in left direction the mouse seemed to continue and I had to move it back the same distance.

It turned out to be a HDMI cable connected to my receiver and from there to my TV. I switched on the TV and found the login screen there. My PC monitor was moved to display 2 and TV was now display 1. I unplugged the HDMI cable so the PC monitor is the only
screen.

 

Bump

I could really use some help. I have work to do on my laptop and rebooring does not help.

 

Is this an unsolvable problem? I seriously could use some help quickly. I do have very important files I need to save, so i am not reinstalling the windows partition.

 

Hi ... Sorry but I'm not sure what you're asking . Are you saying you have no screen on your monitor, If so ? do you have the obvious power to the monitor on ? Did you check your cable not being loose ? And also can you try different cable ?

 

the problem was my laptop screen was black,not sure where monitor came from. i mentioned I was on mac, so that shoulda explained well enough i was on laptop. Well, after opening it for the 'millionth time', it randomly solved itself. I do not understand windows anymore. Is there some fairy that sleeps inside when I am having this problem?(problem has been solved now yes, mysteriously)

 

I know Macs are laptops but when you said you accidentally turn off your screen , you throw me off and I thought maybe your talking about a PC but no sweat . Glad you got it going again . Have a good day
