By searching i found the following fix, see if it helps for you :

• First try by pressing Ctrl+Alt+Delete & see if it removes the black screen. If doesn't then start Windows 7 in safe mode by pressing F8 just before windows 7 boot screen comes.
  
• Now after starting windows, open up notepad and copy following lines in it and save it with "display.bat" name.
  
  

  displayswitch /extend
  displayswitch /internal

• And copy this file in windows startup folder, path is C:/ProgramData/Microsoft/Windows/Start Menu/Programs/Startup, C: refers to your windows drive in which you have installed Windows 7.
  
• Now problem should be fix. Good luck.

I had the same problem. Following solution worked for me:

1. Create a new notepad document
2. Type this text into it: taskkill /F /IM dwm.exe
3. Now save it as displayfix.bat
4. Copy this file to C:/ProgramData/Microsoft/Windows/Start Menu/Programs/Startup
5. Now Restart windows.
