I just got a new LCD Panel (will write a User Review soon, don't worry

) that upgraded my CRT.
When I had my CRT my screensaver was set to "blank screen" after 5 minutes, and then after 20 or so minutes of inactivity I had the monitor power down.
Now with my LCD though, setting the screensaver to "blank screen" doesn't really do much in terms of backlight preservation since the backlight is still on with a screen of black pixels. So I changed my settings to simply have the panel power down after 5 minutes and give me a "really" black screen. This way the backlight doesn't get run unnecessarily if I leave my computer for a little bit.
My question is- is this setting ok to keep? My concern is that constant on-and-off cycles of the backlight are just as bad for it as leaving it run.
