Is your LCD making a buzzing or high pitch noise?
This seems to be a real problem with some LCD Monitors, expecially the entry level 24″ TN panels like the popular Dell E248WFP (which I’m in front of right now).
In my case, the monitor was fine for the first two months. But then started making a buzzing noise… 1) when on, 2) worse when in power stand-by mode, and 3) even worse when turned off.
Thanks Dell!
It seems as if the cheap capacitors manufacturers’ use in these LCDs start to resonate at a high pitch frequency that is very annoying in a quiet room. I’ve read that some people have fixed this by opening up the monitor and putting epoxy around parts … something I was not ready to do.
Adjusting the brightness setting of the LCD managed to fix this problem. Since this changes the power the monitor takes, this also changes the frequency these cheap capacitors resonate at… Sometimes for the better. You’ll have to play around and see what works for you best.
Next time I’m going for a nice non-TN Samsung.
BTW, if any of you have this LCD the color settings are not good out-of-the-box.
Use this profile:
Red:89
Green:92
Blue:97
And my brightness went from 50 to 65.
To fix this, you can also adjust the refresh rate of your monitor, which helps by a lot. I recently fixed my school’s computers with this. It’s fun using your computer skills at school, I’d say.
To change these settings, follow this path:
Start -> Control Panel -> Display -> Settings -> Advanced -> Monitor
Below you will find an area labeled “Screen refresh rate”, or something to that extent.
Simply lower the Hertz at which the screen refreshes, and the problem should be fixed.
