It displays (With a suitable popup for about a second) everything thrown at it via the analog 'VGA' output of my video card.

So yeah, I'd say based on that demonstration that it'd be kinda hard to break an LCD monitor by giving it 'bad' signals... (Although I've never broken a CRT feeding it bad signals either. The best I ever got was having it refuse to display a picture). Mind you we have spent an awful long time trying to solve a problem that probably exists in 10 places around the world (i.e.g can't beg/borror/steal a VGA monitor to bootstrap the card if you want some strange fixed-freq support). [Not that I'm saying don't support it if it's easy enough, but it does seem like an awful lot of time spent discussing & arguing about it].
