Monitor slow to wake from sleep

One of my monitors is very slow to wake from sleep. Sometimes it takes 10 minutes for the display to realize that the computer has woken up and is sending a signal. I have a second monitor attached to the same graphics card, and it has no problems. So it seems like there must be a mistake in the monitor's signal sensor, like somehow it expects more of a signal than it is getting. But the image is fine after it wakes up, so nothing is actually wrong with the signal.

Can anyone give me a suggestion for how to adjust the monitor so that it is more sensitive to the signal in sleep mode? Thanks for your help.

No, it is still blank after cycling the main power. I also tried unplugging and replugging the DVI cable, but that did not help either.

If it's an older LCD with the CCFL backlighting, that is most likely failing. Happens am my workplace all the time. If you shine a flashlight on it, you may be able to see the image on it to try and confirm that the monitor's working, just not the backlight.

This is incorrect, there is nothing wrong with the backlight. I tried shining a flashlight on it, and the screen is 100% blank. When the image appears, the backlight comes on immediately. So the backlight is not any part of the problem.
