I have two monitors connected to a Dell 5750 laptop through a Dell docking station. Recently one monitor died, and I replaced it with another that I had on hand, an Asus PA246Q. That monitor's HDMI port is connected to the dock's HDMI port.
The monitor works fine except that when the computer is in sleep mode, the monitor shifts erratically among four states:
I studied the monitor's manual, but I didn't see anything in the configuration menu that seemed relevant to this problem.
According to Google, the solution is to open the Control Panel's Power Options applet and set the "Turn off the display" and "Put the computer to sleep" options "to values that are appropriate for your usage." That advice seems meaningless, and when I looked at the settings, they seemed irrelevant. Even if this is sage advice that I'm just too dense to appreciate, it doesn't account for the fact that my old monitor behaved correctly and this one doesn't.
Why's it doing this, and how can I make it stop?

- Asleep (backlight off)
- Dark (backlight on, no image)
- A white box with the text "HDMI NO SIGNAL" in the center of a dark screen
- A white box with the text "HDMI NO SIGNAL" in the center of a blue screen
