Display doesn't wake up from sleep

So I have my computer (the one in my sig) set so the display (NOT the computer) goes to sleep after 20 minutes. Lately, when I go to wake it up, the display just refuses to come back on, despite my physically turning the display on and off, moving the mouse a lot, and disconnecting/reconnecting the DVI cable. I usually end up having to restart the computer using the power button. It's kinda been pissing me off, so if someone could help me out that'd be awesome.

  1. Try using Ctrl-Alt-Del (then just hit <Esc>; no need to lock the screen or log out).
  2. Just into control panel and set the video to never go off.
