Fluttering LCD display

It is a defective display panel, not worth to fix.

The fluttering noise you are hearing is an improper gas air mixture. Make sure the vent termination is clear of any debris. You could have improper gas pressure due to a frozen regulator. If the issue does not clear, contact your gas company.

The actuator is causing the fluttering. When they are starting to go out, the locks will flutter. It seems to have more problems in the cold, because the lubrication in the actuator gets thick when it is cold.

The optimum resolution for this monitor is 1280x1,024 @60Hz.
The resolution setting is done at the PC not at the monitor.
After 5 years, more likely components failure will be the filter caps in the power supply section, that will be the first thing to look for inside. You can see failed SAMSUNG monitors here:

you need to have the power supply inspected. look for leaking or blown capacitors. replace them,. very comon problem

I took the advise of someone who wrote in and checked my refresh rate. I found it was at 60 and was advised to change it to 75. So far I haven't experienced any fluttering or wiggling so am hoping this will do the trick. I also checked all the plug in's that were connected to my power strip to make sure they were o.k. I still have one year left on my warranty so may have my monitor checked out just in case I've missed something. Thanks for your offer. I'll be sure to save your website for future questions.

the monitor gets the wrong signal from the computer (refresh rate too high or scan rate too high )
check the screen refresh rate from Display properties / Settings tab / Advanced button / Monitor settings
worse case: damaged hardware

I believe you may be referring to 'pinging', Try a tank of premium gas and see if it stops. Check your timing, and when was it last tuned? Let me know what u find. countrycurt0

Go into advanced settings from the settings tab of "display properties" and select the "monitor" tab, from there, try changing the refresh rate. Toggle "hide modes that this monitor cannot display" if you do not see any other settings in the drop down other than the one that is already selected.

Sounds like the video card, but could be the ccfl inverter starting to go bad or a ccfl lamp going bad.
