I'm using LG Studiowork700E. While processing data from my PC the display of my monitor is fluctuating (it's not exactly flicker but some shadows coming in my monitor). This happens both in WindowsXP and Linux. Any kind of suggestion is appreciated. Thanks

Re: fluctuating display when processing data in my PC
Does it mean that text, or any data found in your monitor has a shadow? There is nothing wrong which kind of system your using (xp, linux) it is on the monitor. It is on the mixing of color, the repair man/technician knows how to adjust those things.

There is a problem with the capacitors in your monitor. This is a normal problem these days with flat screen monitors, I am trying to find out why it is always like tha. This will normally be caused by improper shut down or power fluctuations in your monitor. Capacitrs in your monitor are responsible for holding down the power from the supply, fr the proper display on your monitor. If a capacitor is damaged, or buldged, it no longer holds power long enough for your display, and that is why your screen goes black after a few seconds. This can be solved by opening up your monitor, using a sharp and flat object, opening it starting from the bottom working your way up until the cover is completely out. You will notice finger-like clips that are holding the two covers together. Once you are done, check on the circut board where you connect the power cable.... that is where you are going to find the damaged capacitor(s). You can identify them by noting their bulged head or if there is any liquid coming out of it. Before you replace the, take note of the polarity (+) and (-) so that whenever you replace with the new one it is in the same direction. This will fix up your problem. Note: make sure you let a Computer Technician to do this for you, unless you can do it yourself without damaging the monitor. Thank you
First thing to do is determine whether the problem is the monitor or the PC.
Do you have another PC you could try the monitor on, or perhaps a friend will lend you a monitor for an hour or two?
Obviously if the display is ok on another monitor, then the problem is your monitor, however if the display is still "too big" then the problem is the PC.
By the way, when you say the display is "too large" what EXACTLY do you mean?
Magnet does not affect the LCD panel like the CRT monitor because LCD dose not use electron beams for display function. Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
It means your PC video output resolution is too high for the LG monitor to display (your old monitor (CRT) can handle higher resolution than this LG LCD monitor), you need to set the PC video resolution to native resolutionof this monitor which is 1280 x 1024 @60Hz. You may have to use the old monitor (CRT) to set the resolution to 1280 x 1024@60Hz, then hook up the LCD monitor.
check the data cables.also check if there are power fluctuations. if you do have power fluctuations, try buying a power stabilizer or no-break. if you're under warranty coverage, ask for a replacement (this is the most simple way), if not do what i told you before. the data cables may be malfunctioning. also check your video board. try to plug your monitor into another computer. if the problem persists with a different machine, then the cause is definitively in the monitor.
make sure the lcd monitor is connected to a voltage regulator because if your electricity is fluctuating then that might be a cause of the flickering of the monitor. make sure also that the video card of your operating system is configured properly and the drivers are working fine.
A monitor display showing "No Data" indicates that either the PC is not sending any usable video signal or the monitor is not capable of displaying the incoming video signal. To determine which is at fault, you would need either a known good second monitor or a known good second PC.
Additionally, it is also possible that neither is at fault and that you simply need to lower down the Screen Resolution and/or the Screen Refresh Rate of the computer's display properties to match the limitation/capability of the monitor. A method of verifying if this is the case is to start the PC in "Safe Mode" by pressing F8 after POST before Windows boot.
Alternately, there are some instances that it is the video cable that is the issue. To verify, you can try wiggling the cable to the connector end that goes to the PC's Video output.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop.
If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
