My 144Hz monitor is emitting sounds? - Page 2

On my monitor this coil is not cemented (a generic glue to hold thins in place) to the PCB but I personally do not have this issue... However... several post do mention this and the solution is to glue is down using a glue gun or some such adhesive...

Note that in most of the PCB I have worked on, 99.9% of large coils in power circuits are cemented to the PCB, so why should this be any different...


To find the exact device that's causing the sound (if not the coil), open the monitor and using a piece of plastic, touch it against each of the components in turn (around where the sound is coming form) until the pitch changes... then use the glue gun to alter the resonance i.e.glue it to the PCB...

Thanks Mike.
Seen as the screen is under warranty and Amazon have offered a fast track RMA, I will have a new screen to play with tomorrow. I will test the new screen and post back the results.
Don't have any solutions for GPU "enclosed" coils that whine do you?

You can change the whine (resonance) at which anything oscillates by changing it mass (add a bit of weight to it)... In reality this just changes the resonant frequency to something else hopefully not in the range you use it... wink.gif

By the way, you don't want to go too far... blocking air flow could damage something...

More often than not, the whine is most audible in certain games or resolutions... change drivers, setting or the like sometimes helps...

No noises on my 144hz.

On the newer TBoard (timing board between the DIV board and the actual LCD), I've noticed the two coils are now covered with an epoxied... either noise or stability... take your pick wink.gif
