Black screen bad for displays?

    I sold my Powermac and have purchased an Mac Mini, but in the meanwhile I have been on an old pc I had laying around. I realized this week that the ubuntu machine's screen saver was set to 'black screen,' and the power management panel was set to set the displays to sleep after six hours! This has been going for the past few weeks as I waited for a new machine, and now that the mac mini comes tomorrow, I am worried I have caused undue stress on my two dell monitors.

    Is this something in my head, or is the prolonged display of pure black a problem for LCD monitors?

    If the screen is on for six hours, on a black screen, the backlight is running for the six hours, consuming power and (to a lesser degree) wearing out. Otherwise, no, it doesn't do anything to the LCD panel itself.
