    I've reed on link you directed and it seems to
    be not a specific solution of my problem, but mess of different E-mails related
    to some kind of monitors understandable for electronic specialist.

    But I'm standard PC user, so your answer is puzzle for me even I have
    engineering background.

    So, I'm not accepting this service (and matter of deal is not money amount, but
    your bad answer).

    Sorry, but I expect simple professional suggestion because according forum
    my monitor problem is common.

    Regards,

    Michael

When im on the computer the monitor shuts off a box appears saying power saving enabling monitor to shut down in a few seconds and then it restarts


Windows provides the following plans to help you manage your computer's power:

  • Balanced. Offers full performance when you need it and saves power during periods of inactivity. This is the best power plan for most people.

  • Power saver. Saves power by reducing system performance and screen brightness. This plan can help laptop users get the most from a single battery charge.

  • High performance. Maximizes screen brightness and might increase the computer's performance in some circumstances. This plan uses a lot more energy and will reduce the amount of time that a laptop battery lasts between charges.
    Note

    • High performance doesn't appear on the battery meter by default. To turn on High performance, open Power Options by clicking the Start button ?id=4f6cbd09-148c-4dd8-b1f2-48f232a2fd33, and then clicking Control Panel. In the search box, type power options, and then click Power Options. Under Select a power plan, click Show additional plans, and then click High performance.

If these plans don't suit your needs, you can create your own power plan, using one of these plans as a starting point.

We have just bought an LG 23 inch monitor. Everything okay on it except for the proper resolution. The monitor no. is W2343T. I have put the resolution of 1920 x 1080 and frequency of 60 hertz on it as...


I think the problem is going to be in the Windows software, and not the settings on the monitor. Not sure which type of computer or which Windows you're running, but get into control panel, monitor settings and see what you can do. Windows help and support might be able to assist you.
Here's an excerpt from ncix.com:
Cons Clumsy front panel controls
Vertically, picture is no larger than my old 17"
May require video card upgrade for higher resolutions
Front panel illuminated power button is distracting
Summary Overall, I really like this monitor. But don't expect a size increase vertically over a 17" display. I actually lost half an inch. I prefer a 16:10 aspect ratio so I'm not actually using the full wide available. If you're like me you can save some change and go for the 2243.

Automatic shut off?


Usually you set this by going into the power saving settings in the screen saver settings.

You can set the monitor to shut down pretty much when you want it to from this settings screen.

Good Luck,

Full screen probs with netflix


This has nothing to do with Netflix, you would get the same result with any DVD regardless of its origin. Chances are that is the laptop trying to revert to a screen saver or power save mode during the movie.

Check your laptop's power and screen saver settings. If you are experiencing the problem every 3 minutes or so, your screen saver is most likely scheduled to go on after 3 minutes of inactivity. The same goes for your monitor-- it may try to dim or turn off after a certain amount of time.

To change these settings to a longer delay, go to your desktop and right click. Select "Properties". Choose the "screen saver" tab, and change the "wait:" field to a higher number. Or, just turn the screen saver off by selecting "(none)" under the screen saver dropbox. You may also click "Power" and change the time for "turn off monitor" to "never", or a longer amount of time.

How to turn off the cleaning page feature in Xerox Phaser 8500


Actually what is happening is your machine is going into the power save mode and staying there for a long time.
What happens then is you get a full warmup. When the machine warms up, it will turn on the compressor and drain the resivour because Xerox wants a "fresh": supply of ink in the print head.
Its excruciatingly expensive and wasteful.
Here is something that can help. I am not sure you can completely disable the energy save mode. Thanks Al Gore...
NOTE: To save energy, the printer enters a power saver, low-energy consumption mode after a predefined period of time since its last activity. In this mode, most printer electrical systems are shut down. When a print job is sent to the printer, the printer enters the Warm-up Mode. You can also warm up the printer by pressing the [OK] button on the Control Panel.
If the printer is going into Power Saver mode too often and you do not want to wait while the printer warms up, increase the length of time before the printer goes into the Power Saver mode.
Modify the timeout value:
  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Printer Setup] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Printer Controls], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Power Saver Timeout], and then press the [OK] button.
  4. Press the [Up] or [Down] arrow button to select the required timeout value (30 - 240 minutes), and then press the [OK] button.

    NOTE: Select a larger timeout value to extend the length of time before the printer goes into the Power Saver mode.

  5. Press the [Up] or [Down] arrow button to select [Exit], and then press the [OK] button to return to the Main screen

E-yama 17" flat screen monitor


It sounds like the internal bulb in your monitor is going out. Some LCD monitors go through a slight warm-up period but it should not be 5-10 minutes. You may want to change your Power Saving settings to prevent from going into standby. Here's how:

Right-click in an open space on your desktop
Choose Properties
Click the Screen Saver tab
Down at the bottom look for the Power settings
Change the Monitor Standby to NEVER
Click OK

Good luck!!

Monitor displays vertically


If you mean that your screen display became narrower, then there are usually buttons on the screen to fix this, among other adjustments of the screen. the setting you're looking for has a two way arrow going horizontally through the middle of an icon representing the screen. In case i'm misunderstanding your problem, or this does not help, you can also try to let the screen rest for a while(at least 30 minutes), and turn it back on, to allow it to degauss. Good luck
