I am visiting my parents. I notice their screen makes a buzzing sound when a window is open. the tone changes when the window is reduced. The tone stops when i close the window. I am guessing, this is indicative of a failing monitor. Is there any thing else it could be? A improperly configured audio driver? This is a windows7 computer. I doubt my parents can hear the buzzing.
Adjusting the volume has no effect. The video quality is fine.
