Guest guest Posted November 30, 2008 Report Share Posted November 30, 2008 Can anyone give me some advice on a model of an LCD monitor that does not humm when you reduce the brightness of the screen? Or does anyone have advise on a shield that would reduce the brightness? I did not have problems with an older Dell monitor or an old Fujitsu. My new dell monitor is very bright as most other new LCDs are. The brightness causes sunburn and burns that will not go away. Turning the brightness down, the monitor buzzes. That has led to bad tinnitus. From my research it appears that most LCD screens buzz when you turn the brightness down, unless the design is such that the backlight inverter is shielded. Apparently it is in some models, I don't know which ones. From what I have learned, the frequency modulation that the backlight inverter uses to dimm the brightness is in the hearing range and in this lies the the origin of the buzzing sound and apparently affects my ears. Any comments are welcome. Quote Link to comment Share on other sites More sharing options...
