Hi all

Check for any sources of magnetic fields near your monitor such as speakers , phones etc. Also keep wireless devices such as cordless phones , mobiles away from the monitor. High power adaptors of components such as speakers should also be kept away from the monitor. Check for all these and get back to us. Do you have any other devices near the system which you think can cause interference ? Also check for loose cables and proper power supply. If you are using a ups then try removing the monitor from the ups and connecting it directly to the power source. Do all these and post your reply.

I think it is power problem and the sound is coming from EHT. If your monitor is still under warrenty, immediatly service it to avoid further damage. BTW, never try to open the monitor by yourself. Get it serviced by expert only. Also check the power suppy of your home(Earthing ,voltage,fluctuations etc). Keep speakers and UPS away from the monitor, specially the UPS.

well i cant be sure abt the sound as it has nothin to do with OS or something. it must be a hardware problem.

for flickering i guess u can check for fixing the problem by increasing the refresh rate. u do dat by right click on desktop > display prop > advanced> monitor and select refresh rate to be 85 Hz.... hope it does the job

If all this has not helped you, then its sure that your monitor has a problem; you also told that you have just bought it, so go for a replacement and not for a repair. The Samsung guys will take care of it !!!

I had same problem with my LG monitor. I have noticed that whistling sound only comes when my screen resolution is 800*600. When I change it to 1024*768, sound suddenly stops. So you can check that.
