High pitched noise on PVM 20m4e

[Bancho]

Hi guys

I recently picked up a 20m4e monitor. The picture is great and i've sorted the geometry.

My issue is the it emits a high pitched noise. Now i know its a trait of crts but it seems to be higher and more noticeable on this screen compared to my jvc and 14m2e to the point i find it uncomfortable.

what causes this noise in the first place and is it something i can look to remedy?


Thanks

If it's audible it's probably a lower frequency noise than usual, unless two components are whining and causing beat interference.

Anyhow, I'd look into coil whine. I also understand that capacitors can also generate some noise.

Same on my 20M2E...
