Display not wake up a often

I have a very strange problem with a ZBook G1 17 and NVIDIA Quadro K610M in windows 7, 8 or 10.
I use SendMessage(mi.hwndMonitor, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)2); to turn off the display.
But often not works fine.
It power off monitor, but when I press a key, the monitor power on but the screen remain black
Then I have to suspend in ram the nb with power off button configured and power on to have monitor wake up.
This happens especially when:


- Wake up before 90 seconds work fine.
- Wake up after 90 seconds black screen. (but 1% success also)
- Wake up after long tme but first at OS boot again black screen.

I tried, But without success:
- PauseResumeThreadList(2)
- {win}{ctrl}{shift}b
- Full Uninstall driver and reinstall last and old from HP and Nvidia
- Replace Ram
- Modify Windows power option

- Update and Modify Bios option
- ...

everything works 100% perfectly, the only stain is black monitor when use SC_MONITORPOWER.
I tryed also Nvidia support here.
Could you suggest me some way to solve this problem?
