detecting monitor's sync and refresh rate?

[Anton Shterenlikht]

I've a monitor (Mobi M15MPC) with no docs.
I've searched the net but cannot find any info on sync and refresh rate for it.
I've done Xorg -configure, but testing with X -config xorg.conf.new
shows screen shifted to the side and very nasty blinking, from which 
I deduced that perhaps I need to specify correct sync, refresh and mode.

Are there any commands to get sync and refresh from the monitor?

many thanks
anton
