I also have a T560i.  The monitor will beep for several reasons to indicate an
error condition.  When I first got the monitor, I adjusted all video modes to
provide a maximum image size.  Over time, or perhaps due to temperature,
things drifted a bit, and the monitor started beeping.  I found that if I
backed off the horizontal width just a touch, the monitor was happy.

Try decreasing all available parameters to see if you can make the beeping
disappear.  To see if this is the same error beep, increase the horizontal
size until the monitor beeps.  If the noise is different, say a high pitched
whine, it may indicate a problem in the power supply or one of the other
coils/transformers in the monitor.

Good luck,
