LCD Monitors- Should They Be Turned Off When Not in Use?

LCD monitors have better lifespans than the big CRT monitors, so I'd say you don't have to worry about it (even though I turn mine off whenever I'm not using it). Also, if no other problems arise, & the backlight needs to be replaced, it can be done no problem, while to replace a CRT monitor you need to buy the whole thing. LCD monitor backlights generally have a lifespan of about 60,000 to 80,000 hours--about 20~25 years of daily 8-hour use. Don't sweat it.

Even with the CRTs the problems was never really one of "burning out" but "burning in". The original reason for turning them off was that if you left them running the image on the screen didn't change and it would burn into the screen and be there forever as a shadow.

I lave my LCD panel at work running all the time. It's been on since I got it back in August. *shrugs*

Thanks, guys. I am going to relay the message to my husband!

"Burning out" was a bit of a problem with CRTs, but mainly for people who'd buy them 2nd hand then use them for a few more years. 4~5 years of continual use will take a BIG chunk out of a CRT's brightness.

It does how ever use a lot of power.

Yep - I understood that to be the case - so I always turn my screen off when I will be away for some time.

So tell me - if I use my computer 4-5 times a day should I leave it on or turn it off in between - and why?

Computer, or monitor?

monitors yes, computers no

Computer
Yes what - no what?

The computer itself uses very little power when left on, so you don't have to turn it off. The monitor uses a ton of power, so if you rarely use the computer, turn the monitor off.
From an environmental point of view.

Thank you

LCD Monitors
Yes, but don't things like fans wear out in the CPU? So wouldn't turning it off save wear and tear?

OK, so I compromised. I set the computer to turn off the monitor after I have been away for 10 minutes. Now everybody's happy over here!
