Is my monitor die'in?

[silly_rabbit]

started sometime last week, my monitor have a high pitch tone
when there is no signle from the video card (like when booting
when the screen goes all black it'll do that, I think if I
unplug the video cable it'll do the same thing too)

do you think my monitor is dieing? If so, what could be the problem
could it be because the monitor refreshes at 75Hz, but I set up
my video card to do 85Hz?

uh YES.
look at your monitor booklet. It will tell you what are the maximum refresh rates at most popular resolutions.
Its HIGHLY ADVISED you do not exceed such specifications.

E.g. For my viewsonic 17" monitor its max scan frequency is 97Khz or 97000 Hz.
thus at 1600x1200 it can do approx 97000/1200 = 77Hz max refresh rate.
At lower resolutions it can obviously do higher refresh rates.

High pitched tones are usually a sign of monitors slowly dying too.

A high pitched noise can be serious (capacitor failing) or nothing (coil resonating), but it's always best to keep the horizontal scan rate as low as possible, to reduce stress on the flyback transformer, capacitors driven by it, and the horizontal output transistor. This rate is the refresh rate multiplied by the number of horizontal lines.
