I just replaced my wife's NEC 19" CRT with an ACER 22" LCD. When I set the power management ot turn off monitor after 2 hours, it turns off...however, when we move the mouse the monitopr only partially reawakens. We get a distorted versiion of the XP desktop with no task bar or desktop icons. The only way to resolve this is to reboot the PC.

I don't have this problem with other PCs in the house nor did we have this problem with the CRT.

Any ideas how to correct this?

Hi Clyde and welcome to the forum. I never turn off my monitor. When I shut down the computer, it goes into a sort of hibernation and when I restart the computer the monitor comes back up. I don't understand the reasoning behind putting just the monitor in hibernation as usually, if you put the computer in Hibernation, the monitor will follow. My guess it is because of putting just the monitor in hibernation and not the computer, it could be causing a problem on restart of the monitor. When you reboot, the computer then all of the drivers and such come up and all is fine. coastie65

Yup.... I never turn OFF my monitor , most of monitors come with signal detection....It'll turn itself off "Pc OFF"....and on when it detects an input "Pc on"

I 'd put all the Pc setiings baxk to default ,

Hi T4Me, I, by no means, am an expert on the subject but I've heard, from those 'energy efficiency experts' (?), that one of the appliances that uses the most electricity in the household is the ..... Monitor. They say to turn it off every chance you get to save on hydro....but who knows? I wonder if that survey was based on those humongous CRT monitors, whereas possibly the newer LCD's don't use as much.

To each his own.

Hey Yep, It was probably based on the CRT's. I don't think LCD's use that much anyway. You turn off the computer and when no signal is detected the monitor goes int hibernation until the the computer is restarted and it gets a signal. These nuts and their conservation methods, are using more energy through their methods in a lot of cases. Being on a small fixed income, I'm all about conservation, as it cuts down on my utility bills. coastie65

Hi Yepy. Yes , the CRTs take about triple (if not more) energy consumption than Lcds "only use small Dc"

I was in the version of trying to give you help with your problem , then Its up to you to leave it on/ off to save energy.

Hi ClydeScott and welcome to the PCWorld Communities. :D




Please provide the system specifications of your computer. The most important piece of information we need is the total amount of memory you have installed in this computer.

Hey Tech, Yep wasn't the one with the problem, Clyde was. He just chimed in with that bit of info. coastie

Thanks for all your comments, but I resolved the isse this afternoon. It seems that somehow both the VGA and Digital video cables were connected to the monitor. When I disconnected one of them and reset the power settings to turn the monitor off after a long period of non-use (which DOES prevent premature pixel burnout & provides some power savings) the monitor returns to normal state as expected.

THIS ISSUE IS RESOLVED!

[Tech4me]

Clyde. glad it works out for you...sometime Its just a simple thing We might over look.

Good job.

[coastie65]

Hey Clyde glad you found it. You didn't say you had both cables hooked up. Thanks for sharing the solution. As for premature Pixel burn out, on an LCD, I don't think it is an issue, or at least I haven't heard of it as yet. coastie

[Tech4me]

Coastie. I think the "burn-in" only happens to Plasma panels not Lcds.

[coastie65]

That's the only thing I've heard of it having to and now not so much with them.

Clyde,



Go into your Display Settings dialog box and make sure you're doing two things first.



Right click desktop, select Properties, and click the Settings tab.



Click the "Advanced" button.



What does it say under the monitor tab? Does it accurately state that you're running the Acer 22" monitor or does it say something about "Generic Plug and Play" or "non plug and play" or such? If it does, you need to download the "drivers" from Acer's support site unless the monitor included a disc. (Actually calling it "drivers" is a real stretch since the file is usually just a text file list of settings and info on compatible modes and settings for your Acer monitor.)



I'd like to tell you how/where to download the appropriate file for your monitor (hopefully it came with a disc), but alas I cannot. Acer's support site/page links are broken or ridiculous in search results. Another example of lame Acer support. Gawd.... I wish they'd get their act together with support! Acer's main support site is:

http://www.acersupport.com/

Good luck.



If you can get your Windows to show the correct monitor and if the monitor is running at its native mode settings (the setup sheet in the box with the LCD had this information), it should work.



Back in your display settings dialog box, go over to the Screen Saver tab and check that its set to none. A lot of times, fancy screen savers conflict with other things; if your plan is to sleep the monitor, don't use them. (E.g. While Picasa was in Beta, the Google screensaver would sometimes lock up my PC. A later patch fixed it. Even early Vista Bubble screen saver was known to lock up some PCs.)

Then check under the energy star button - Power Management - and check that its set to Turn Monitor OFF after X minutes (I'd suggest 15), and make sure the system is not set to go to standby or hibernate at a time equal to or less than the monitor and HD off settings. (If you're in the habit of shutting down overnight or while you're away for long time periods, set it to never go to standby or hibernate.) Go to Hibernate tab and turn it off.



We have 5 LCD touch screen NECs P.O.S. systems at work, they ALL show burn in. So, yes, LCDs can have burn in, at least at some level.
