Windows 7 Forgets the 2nd screen?

Unfortunately I have the problem at the moment that my notebook forgets the second screen after each restart of the notebook. After every start I have to select the screen with Win + P. After that everything works without further problems but unfortunately it is very annoying. Do you have any suggestions on how to fix this attitude?

Have all the energy settings also changed, worked well but only for about 2 weeks. Now I have the same problem again.

Does that help?
