Hi, constant high pitched whine from most monitors have something to do with the horizontal frequency which is partly affected by the screen resolution as set in your computer display properties. Try lowering down your resolution or go into safe mode. if the whine disappears, it may be that the monitor is not fully capable of displaying too high a resolution. If the whine continues even at safe mode or lower screen res, then you would need to consult a qualified technician to check for defective components in the horizontal circuitry of your monitor. I wouldn't recommend that you take look due to the presence of extremely high voltage in that area. Hope this be of some help. pls post again how things turn up. kind regards.
