    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

Explain how the monitor buttons work


Monitor Icon Description of icon function moncont.gif Power - Turns the monitor on or off.
Brightness - Using this button or wheel the user can increase and decrease the brightness on the screen.
Contrast - Using this button or wheel can increase and decrease the amount of contrast on the screen.
Horizontal Size - Allows for the picture on the screen to be stretched to the horizontal edge of the monitor.
Vertical Size - Allows the picture on the screen to be stretched to the vertical edges of the monitor.
Horizontal Position - Allows the picture to move moved horizontally, once in the center the user can then use the Horizontal size to stretch it to have an equal amount of black border on each side.
Vertical Position - Like the Horizontal Position, using this button or wheel the user can move the picture up or down to center the picture more appropriately.

Moire - Removes or reduces the Moire effect, if any.
OSD Controls - If the monitor contains OSD controls, allows for the OSD menus to be adjusted.
Power Management - Allows the user to define the power management settings through the monitor itself and not the software.
Monitor Status - Displays the current monitor settings such as refresh rate and other settings.
Language - Sets the language on the monitor.

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,

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!!

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

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
