how to find the specs of a monitor

[Kamaraju S Kusumanchi <kamaraju@bluebottle.com>]

I am trying to setup a dual screen from a laptop with another LCD monitor.
However, this new monitor came without any manuals, documentation etc., I
know that it is working but I just dont know the specs. How can I find out
what its Horizontal frequency and vertical refresh rates etc. are, so that
I input them into the monitor section of xorg.conf file?

If it matters, the laptop as such runs Etch (stable).

Any ideas?

thanks
