How to extinguish both monitors at the same time?

Two monitors connected to the graphics card: one via HDMI, the other via DisplayPort.
When Windows turns off the monitors after a time specified in the power profile of the first monitor just goes out, and the second writes on the screen that there is no signal.
How to make both monitors shut down?

DELL monitors, graphics card MSI GTX660

I guess you need to take the same monitors (not just one manufacturer, for example Dell, but quite the same). In fact, both monitor when you programmatically disable (i.e., removal of a signal) do not remove the food and go into hibernation, and the difference in how this process looks, is due only to program stuffing their controllers. If it is the same, there's no reason to neodnorodnosti.
However, if they have their own configurable OSD menu, then the difference may be caused by a difference in these settings.
Would you mind telling me why you need such a strict simultaneous extinction? In my opinion, there's no practical sense. Tried to dream up on this subject, but to no avail.

is the taming of my OCD -- it's impractical? - Dangelo.Web commented on April 19th 20 at 12:28
The monitors are exactly the same. Proschelkal menu, are configured identically. Will try to do a reset on both.
Need because though the matrix shows a black picture, but still shines at night ) - amira_Wiza commented on April 19th 20 at 12:31
@amira_Wiza, Yes, the matrix is showing black picture, transparent (albeit poorly). But first, she needs to Shine equally on both monitors (again, I see no reason for a difference), and second, the backlight of the screen when hibernation should be turned off no more than a minute. So the minute you can wait. - Myah.Auer60 commented on April 19th 20 at 12:34
@Myah.Auer60can. And you can not wait. The 21st century well - amira_Wiza commented on April 19th 20 at 12:37
In any case, thanks for the comments - amira_Wiza commented on April 19th 20 at 12:40

If the monitors are the same, try to swap the connection type, what happens?
Perhaps the scaler reacts differently to different signal sources
Try changing the HDMI cable, perhaps it does not pass through the switch-off signal
OK, thanks, I'll try. The problem is really the monitor that hdmi is enabled. And the cable since some - amira_Wiza commented on April 19th 20 at 12:30
