[Solved] Display "No Signal"Could not start Display server on vt 1

Hello,
sorry for my english
is my first post, I'm a newbie and have a direct question:
I have a new Nvidia card installed before an AMD card was installed.
When I start my PC and do not turn on my monitor before, if Linux is already started
then turn on my monitor gets from my Benq Zowie only a "No signal".
If I press ctrl+alt+f2 and enter my password and startx  my monitor turns on.

However, if I start my monitor before I start the pc, I can get into sddm without any problems.
