I have a late 2008 macbook pro with a mini displayport to dvi adapter.

When I plug the adapter in to an external monitor or TV the laptop screen and the monitor sync for a second (both screens turn light blue before the the desktop shows up - the usual process) and then un-syncs again, over and over.

almost like this

I have tried an external monitor and a LCD TV, and used a dvi-dvi cable and a dvi-hdmi from the mini displayport-dvi adapter, same result.
In the past I have connected my mbp to several tvs, monitors and all worked fine

has anyone had any problems with this, or can they offer advice?
