I have a Dell xpPro laptop and was wondering which
is the best way of managing the LCD monitor life.
Is turning the monitor off in a short cycle, 5-10
minutes when not in use, shorten the backlight
lifetime compared to a longer setting, such as
45 minutes to an hour. My understanding is that
screensavers that protected CRTs from image
burn-in are not as effective on LCDs since the
technology of image creation is so different.
The periods of inactivity vary so I don't want to
make the period so short that it is frequently
restarting if cycling is shortening the life more
than just leaving it on, but don't want it on for
pointless hours when not in use. How does one
determine the best interval?
Thanks, westpase
 
Screensavers have moved to the entertainment side of the ledger, burn in
on even CRT monitors has not been an issue since they quit long
persistance phosphor screens. (about a decade now) As for the backlight,
you shouldn't get to concerned. It will last until it quits.

My PC is 3 years old and I see no change in the LCD quality. I'm not
sure I would spend a lot of time. I'd advise you to do what works.

I have a Dell Inspiron 6000, and the BIOS power management for the LCD
was set for 60% dim on battery and 100% on power. I changed to 100%
all the time. I do put it into sleep whenever I'm off for a while
though. It's a faster recovery than power off, and the drive does not
heat up as much. I guess I save the drive/battery/screen but I don't
do it for that reason.

LCD screens do not suffer burn in. Screen savers are provided these days
because they are cool (as my nephew would say). The backlight is a
different story, but it will almost certainly vastly outlast the monitor.
In fact restarting the backlight may well do more to limit its life than
just leaving it on.
