Given that this has just started recently and is getting worse, I'm inclined to suspect that the monitor's flyback transformer may be going bad. Doubly so if the other monitors are the same model and, with identical RH installs, they're not making the same noise. If you don't have one already, I'd suggest at least getting your hands on a spare monitor in case the noisy one fails. -- Linux will do for applications what the Internet did for networks. - IBM, "Peace, Love, and Linux" Geek Code 3.1: GCS d? s+: a- C++ UL++$ P++>+++ L+++>++++ E- W--(++) N+ o+ !K w---$ O M- V?
