One of my monitors is buzzing with varying degrees as I go from web page to web page. It's loud enough to be heard from another room and extremely annoying. Is this the beginning of the end for it? My other monitor just kept getting duller and duller. It has since leveled off but I can't get it any brighter either through the manual controls on the monitor or the display settings in the control panel. I think the problems are unrelated because the dim one started long before the noisy one. Both are CRT.
